Nerve injury in revision total elbow arthroplasty: a systematic review and meta-analysis.

BACKGROUND: Revision total elbow arthroplasty (TEA) is technically demanding and carries a substantial risk of postoperative neurological complications because of scarring, altered anatomy, implant removal, and repeated humeral and ulnar exposure. The incidence, nerve distribution, and recovery profile of nerve injury after revision TEA remain incompletely defined. This study aimed to systematically review the literature to define the incidence, recovery profile, and risk factors for nerve injury after revision TEA. METHODS: A systematic review of the literature was performed in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidance. Thirteen retrospective case series were included, comprising 282 revision TEAs in 271 patients. Random-effects meta-analysis of proportions was undertaken where the data permitted. The primary outcome was postoperative nerve injury following revision TEA. Secondary outcomes included nerve type, recovery, secondary nerve-related procedures, infection, triceps insufficiency, metallosis, periprosthetic fracture, and re-revision. RESULTS: The pooled incidence of postoperative nerve injury was 22.3% (95% confidence interval [CI] 16.3 to 29.6; I2 = 34.6%). The crude incidence was 60 of 282 revisions (21.3%, 95% CI 16.6 to 26.5). The ulnar nerve was involved in 66.7% of all nerve injuries, the radial nerve in 31.7%, and the median nerve in 1.7%. No significant difference in pooled nerve-injury incidence was identified between studies published before 2010 and those published from 2010 onwards (22.9% vs. 21.4%, P = .837). Recovery reporting was heterogeneous; among injuries with numerically extractable outcomes, 85.4% improved partially or completely (95% CI 72.2 to 93.9). Secondary nerve-related procedures were reported in 7 studies. Pooled complication estimates were 10.2% for infection, 13.6% for triceps insufficiency, 25.5% for metallosis, 15.9% for periprosthetic fracture, and 14.0% for re-revision. CONCLUSIONS: Postoperative nerve injury is a common and clinically important complication of revision TEA, affecting approximately 1 in 5 cases. The ulnar nerve is most frequently involved, although radial nerve injury accounts for a substantial proportion of cases. Many neuropathies improve during follow-up, but persistent deficits and the need for secondary nerve-related procedures are not uncommon. Future studies should adopt standardized neurological definitions and reporting to improve comparability and guide preventive surgical strategies.

Postoperative Curvature Loss in Three-Level Anterior Cervical Discectomy and Fusion With Zero-Profile Device.

PURPOSE: Cervical curvature loss is a frequent complication following 3-level anterior cervical discectomy and fusion (ACDF) using a Zero-Profile device. Consequently, the capacity of this device to maintain cervical sagittal alignment in 3-level ACDF remains highly controversial. This study aimed to identify potential predictors for postoperative curvature loss (PCL) and evaluate its impact on clinical outcomes. METHODS: A total of 113 patients who underwent ACDF for 3-level cervical degenerative disc disease (CDDD) between January 2021 and December 2023 were retrospectively reviewed. Demographic data, radiological parameters, and clinical outcomes were analyzed. Radiographic measures included cervical curvature, T1 slope, C2-7 sagittal vertical axis, and titanium plate and endplate (TPE) distance. Clinical outcomes were assessed using the Visual Analog Scale (VAS), Neck Disability Index (NDI), and Japanese Orthopaedic Association (JOA) scores. Statistical analyses were performed using paired and independent t-tests, as well as Pearson correlation coefficients. RESULTS: The average curvature loss was 6.82° from 1 week postoperatively to the final follow-up (p < 0.001). However, the final curvature (11.65°) was maintained, representing a 4.33° improvement compared to preoperative values. Significant correlations were observed between PCL and preoperative curvature (r = -0.368, p = 0.013), preoperative T1 slope (r = -0.546, p < 0.001), ∆T1 slope (r = 0.443, p = 0.002), and ∆TPE distance (r = 0.417, p = 0.004). PCL did not correlate with Japanese Orthopaedic Association (JOA) scores or arm VAS scores at the final follow-up. Nevertheless, patients with a PCL ≥ 6° exhibited significantly higher neck VAS (p = 0.028) and NDI scores (p = 0.041). CONCLUSION: Although contiguous 3-level ACDF with a Zero-Profile device may result in PCL, it preserves an improved cervical lordosis compared to the preoperative baseline. Low preoperative curvature and a low preoperative T1 slope are potentially predictive factors for PCL. Postoperative changes in TPE distance and T1 slope are significantly associated with PCL, suggesting a potential biomechanical link that requires direct validation. Furthermore, PCL may lead to higher neck VAS and NDI scores. Consequently, the Zero-Profile device may require careful consideration in 3-level CDDD patients presenting with low preoperative curvature and a low T1 slope. Importantly, the 6° PCL threshold identified is preliminary and requires prospective validation before clinical application.

Evidence-based insights into medial pedicle reduction mammaplasty: A systematic review and meta-analysis.

BACKGROUND: Breast reduction relieves the physical and psychosocial burden of macromastia. Medial pedicle reduction mammaplasty may enhance vascular reliability, preserve nipple-areola complex (NAC) sensation, and sustain upper pole fullness, even in large-volume reductions. The purpose of this study was to assess the outcomes of medial pedicle breast reduction. METHODS: A search across ScienceDirect, Cochrane, and PubMed was conducted. Included studies reported on perioperative outcomes and complications of medial pedicle breast reduction. Data on demographics, surgical variables, complications, sensory recovery, volumetric changes, and patient satisfaction were extracted. Proportion meta-analysis was performed, and odds ratios were calculated for comparison with inferior pedicle breast reduction. RESULTS: Twenty-five studies comprising 1033 patients met the inclusion criteria. Mean BMI ranged from 27 to 42 kg/m2, with mean resection weights between 412 and 3828 g. Mean surgical times ranged from 104 to 204 min. Pooled complication rates were low: infection 1%, seroma 1%, hematoma 1%, fat necrosis 2%, NAC necrosis 1%, dehiscence 8%, and reintervention 5%. Odds of complications did not differ significantly from inferior pedicle reductions. NAC sensation typically recovered by 6-12 months, with no long-term deficits. Volumetric analyses demonstrated stable breast shape after the first postoperative year, with superior upper pole tissue maintained. Patient satisfaction ranged 75-100%, with higher ratings for scar appearance and overall aesthetics in medial pedicle reductions. CONCLUSION: Medial pedicle breast reduction is a well-established and reproducible technique, preserving NAC sensation, achieving stable long-term shape, and enhancing upper pole fullness. It offers satisfactory aesthetic outcomes compared to other traditional methods, even in large-volume reductions.

Risk Factors and Predictive Model for Postoperative High Myopia in Children Undergoing Congenital Cataract Surgery With Intraocular Lens Implantation.

PURPOSE: To identify risk factors associated with the development of high myopia following congenital cataract surgery and to establish a robust predictive model. DESIGN: Retrospective clinical cohort study. SUBJECTS: This retrospective study included 106 pediatric patients who underwent congenital cataract surgery with primary IOL implantation (mean follow-up 8.19 years). The model was externally validated in an independent cohort of 72 patients with a mean follow-up of 7.83 years. METHODS: Preoperative and postoperative ocular biometric parameters were collected. Risk factors for postoperative high myopia were analyzed using Cox proportional hazards regression, which served as the basis for model construction. The predictive performance of the model was rigorously evaluated for discrimination and calibration. Discriminative ability was quantified using Harrell's C-index and the area under the receiver operating characteristic curve (AUC). Model calibration was assessed via calibration plots by comparing predicted probabilities with actual observed outcomes. Internal validation was performed using a bootstrapping method (500 iterations) to ensure model stability and adjust for potential overfitting. RESULTS: An initial postoperative refraction of <+0.75D, and a higher IOL Power to Axial length Ratio (IOL/AL ratio) were identified as significant risk factors for the development of postoperative high myopia. Shorter preoperative axial length was associated with a greater magnitude of postoperative myopic shift. The predictive model demonstrated robust performance, achieving a C-index of 0.711 (internal validation C-index: 0.713). The area under the receiver operating characteristic curve (AUC) values for predicting high myopia at 5 and 10 years were 0.858 and 0.745, respectively. Furthermore, calibration curves demonstrated excellent agreement between the predicted and observed outcomes throughout the follow-up period. In external validation, the model achieved a C-index of 0.825, 5-year AUC of 0.833, and 10-year AUC of 0.713. CONCLUSIONS: Our analysis established that initial postoperative refraction <+0.75D, and an elevated IOL/AL ratio are key determinants of high myopia risk following surgery. Shorter preoperative axial length was associated with a greater magnitude of postoperative myopic shift. This predictive framework provides clinicians with a practical tool to optimize preoperative IOL selection and identify high-risk infants who require vigilant myopia prevention and balanced amblyopia management.

A randomized study of antibiotic prophylaxis after hypospadias repair in children.

BACKGROUND AND OBJECTIVE: Antibiotic resistance is a challenge in contemporary world. Urethroplasty for hypospadias is one of the most common urological surgeries performed around the world, yet, there is still no consensus on the use of antibiotics pre- and post-operatively. Our objective was to analyze the effectiveness of antibiotic prophylaxis and therapy before, during, and after hypospadias repair in children. METHODS: A prospective randomized trial was carried out including patients with coronal hypospadias who underwent urethroplasty performed by one surgeon. Urethral catheters were used in all cases for 10 days. Study participants were randomly assigned in a 1:1:1 ratio to receive a single intraoperative administration of antibiotics (Group I); an intraoperative antibiotic prophylaxis and antibiotic therapy for 10 days until the removal of urethral catheter (Group II); no antibiotic administration (Group III). Randomization was performed using computer-generated permuted blocks with randomly varying block sizes, prepared by an independent statistician. The results were analyzed using the analysis of variance (ANOVA). The following criteria were compared: postoperative functional complications, such as: urethral fistula, stenosis, diverticulum; wound infection symptoms: hyperemia of surgical site, pain during palpation, and symptomatic urinary tract infection. RESULTS: A total of 300 patients were included in the study. Two patients (2%) in Group I, two patients (2%) in Group II, and four patients (4%) in Group III had urethral fistulas, requiring surgery 6 months after primary repair, yet without statistical difference between groups. We found no significant difference in frequency of symptomatic UTIs between three groups (p = 0.182). CONCLUSION: There is no effect of antibiotic prophylaxis and therapy on the frequency of postoperative surgical and infectious complications after urethroplasty for coronal hypospadias repair in children.

Long-Term Survey to Assess Recurrence and Complications of Surgically Treated Pleomorphic Adenoma.

OBJECTIVE(S): To (1) report on the long-term recurrence rate of surgically managed pleomorphic adenoma (PA) and (2) assess long-term surgical outcomes after parotidectomyMethods:Cross-sectional survey of all patients with a pathologic diagnosis of PA who underwent surgical management in a tertiary care center from 01/1997 to 12/2023 and had access to an electronic patient portal. Surveys were delivered via electronic patient portal or phone call with 6 questions to assess recurrence and long-term surgical outcomes. Time to first recurrence and recurrence free survival were analyzed using a Kaplan-Meier curve. RESULTS: Seven hundred-forty-five patients met inclusion criteria and received the survey, with a 56% response rate (n = 420). The clinical median follow-up length was 51 days, which extended to a median length of 6.2 years following the survey. The median change in follow-up length was 5.37 years (P < .001). The recurrence rate was 1% at 5 years, with a median time to first recurrence of 7.54 years. 13% and 9% of responders reported facial asymmetry and incisional cosmetic concerns, respectively. 33% of patients reported experiencing Frey syndrome, which increased from 5.2% of survey responders with documented Frey syndrome at their original post-operative assessment. CONCLUSION: Long-term assessment of PA outcomes confirms low recurrence rates, suggesting regular surveillance of recurrence is likely unnecessary. Complaints of Frey syndrome increased in frequency with longer term follow-up, which should be considered during patient counseling. LEVEL OF EVIDENCE: 3.

Beyond da Vinci: a systematic review of next-generation multiport robotic platforms in pediatric surgery.

As robotic surgery expands beyond the da Vinci platform, the relevance of new-generation systems to pediatric patients remains uncertain. This review examined the technical characteristics, applications, and perioperative outcomes of alternative multiport robotic platforms in children. PubMed/MEDLINE, Web of Science, Scopus, and the Cochrane Library were searched through 28 February 2026 in accordance with PRISMA 2020. Owing to clinical heterogeneity, findings were synthesized narratively, with Wilson 95% confidence intervals for key binary outcomes. Six studies reported 166 patients across 27 procedure types. Senhance accounted for 164 patients, while Hugo RAS and Hinotori were each represented by one patient. Ages ranged from 15 days to 17 years and weights from 3.8 to more than 100 kg. Senhance was the only platform used with 3-mm robotic instruments. Conversion or planned escalation occurred in 19 patients (11.4%; 95% CI, 7.5-17.2%). Four intraoperative complications were reported (2.4%; 95% CI, 0.9-6.0%). Across all reports, 20 patients experienced postoperative complications (12.0%; 95% CI, 7.9-17.9%). In the largest cohort, seven patients required reintervention (4.6%; 95% CI, 2.2-9.2%) and seven were readmitted (4.6%; 95% CI, 2.2-9.2%). No deaths or comparative pediatric studies were reported. Published experience remains sparse and is almost entirely limited to Senhance. Current evidence describes early clinical use without establishing comparative safety, effectiveness, or platform superiority. Prospective multicenter studies with standardized reporting are needed.

A retrospective population-based cohort study to assess outcomes, time to complications and cost of follow-up care following pediatric pyeloplasty in Ontario, Canada (2002-2016).

PURPOSE: Pediatric dismembered pyeloplasty (PP) is the gold standard surgery for uretero-pelvic junction obstruction (UPJO) in children. However, there is no consensus regarding the duration and methods of providing follow-up care after PP. This study aims to assess the rate of redo-interventions following PP and to define the ideal follow-up care following PP. MATERIALS AND METHODS: This is a retrospective population-based cohort study including all PP patients in Ontario between April 2002 and March 2016 using routinely collected data, with a minimum 5-year follow-up. Baseline variables included demographics, surgical approach, laterality and surgeon experience. The primary outcome was time to secondary surgical intervention, including redo PP. Secondary outcomes included costs of follow-up care and rates of early ER visits. Regression analyses were preformed to predict need for secondary intervention 2-years post PP, including independent variables: age, sex, surgical approach and early complication. RESULTS: The study included 1049 patients with a median age of 2 (IQR 0-7) years. Of the 13.6% of patients who had at least one secondary intervention following PP (including 3.8% who underwent a redo PP), 90.2% occurred within 3-years of PP. The median cost/patient of follow up care was $1472 CAD (IQR $292-$31,133). Regression analysis did not reveal any predictors of delayed secondary intervention. CONCLUSIONS: This study demonstrates that over 86% of PP are completed successfully, with a 3.8% rate of redo-PP. The majority of secondary interventions for post-PP complications occur within 3 years post-PP. Variability in duration and cost of follow-up care post- PP should be addressed to minimize costs, and a minimum 3-years follow-up after PP is recommended.

Surgical management of esophageal atresia with tracheoesophageal fistula in extremely low birth weight neonates: A systematic review.

BACKGROUND: Surgical management of esophageal atresia/tracheoesophageal fistula (EA/TEF) in extremely low birth weight (ELBW) neonates remains challenging and controversial. This study systematically reviews surgical strategies and outcomes in this population. METHODS: Following PRISMA guidelines, Cochrane, Embase, MEDLINE, Scopus, and Web of Science (2004-2024) were searched in February 2025 for studies on surgical management of ELBW neonates with EA/TEF (PROSPERO CRD42025636228). Fatal chromosomal abnormalities were excluded. Demographics, comorbidities, surgical techniques, and complications were analyzed descriptively. Risk of bias was assessed. RESULTS: Eleven publications (five case reports and six case series) comprising 30 patients (Gross type B/C = 1/29) met the eligibility criteria. Mean gestational age was 28.1 (23-34) weeks, and mean birth weight was 760.4 (422-995) g. Twelve primary repairs (PR) and 18 delayed primary repairs (DPR) were performed, including staged repair (n = 11), lower esophageal banding (n = 4), and other techniques (n = 3). Postoperatively, four anastomotic leaks were managed conservatively, six strictures and one recurrent TEF required endoscopic intervention, three fundoplications and two aortopexies were reported (follow-up: 1-198 months, n = 19). Overall mortality was 30% (PR: 8.3%; DPR: 44.4%). Mortality was 60% among neonates with major congenital heart defects (CHD) and 40% among those with VACTERL association. EA/TEF-related complications contributed to 33.3% of deaths. CONCLUSIONS: Mortality in this cohort remains high, particularly with major CHD, and is largely unrelated to EA/TEF-specific complications. In selected cases, PR appears feasible as an alternative to DPR, although conclusions are limited by the small sample size and heterogeneous studies.

Posterior Segment Risk Factors for Penetrating Keratoplasty Failure.

PURPOSE: To analyze the relationship between intraoperative and postpenetrating keratoplasty (PK) posterior segment variables and PK graft survival. DESIGN: Retrospective clinical cohort study. SUBJECTS: Patients undergoing PK between May 1, 2007 and September 1, 2018 at a single tertiary center. METHODS: Chart review for PKs performed was conducted, and the first PK completed at the institution for each patient was included for analysis. Data collected included demographics, medical and ocular history, preoperative and intraoperative findings, and intraoperative and postoperative posterior segment factors (pars plana vitrectomy [PPV], endolaser, retinal detachment [RD], and vitreous hemorrhage [VH]). After univariable analysis, variables were selected for multivariable Cox regression analysis. MAIN OUTCOME MEASURE: Graft failure, defined as irreversible and visually significant corneal edema, haze, or scarring. RESULTS: Eight hundred and thirty-five eyes of 835 patients were included. Mean age was 57.1 ± 22.0 (range: 0-100) years, and mean time from PK to final follow-up or graft failure was 3.2 ± 2.9 (range: 0.01-16.1) years. Graft failure occurred in 35.0% of cases with a mean onset of 1.9 ± 2.0 (range: 0.04-11.4) years after PK. After multivariable analysis, 9 variables had significant associations with failure. Two posterior segment variables were significant: intraoperative VH at the time of PK (hazard ratio [HR] 6.6, 95% confidence interval [CI] 1.6-27.7, P = .010) and silicone oil (SO) tamponade after the PK (HR 3.2, 95% CI 1.4-7.4, P = .007). CONCLUSIONS: Graft failure is a serious complication of PK. VH at the time of the PK and SO tamponade after the PK were associated with graft failure. In complex eyes that are undergoing PK grafts and that may also require posterior segment interventions, these findings may guide patient counseling and discussion of graft prognosis.

Surgical outcomes and complications of fixation strategies for distal tibial fractures: a systematic review and network meta-analysis.

BACKGROUND: Multiple fixation options exist for distal tibial fractures, but the optimal approach remains controversial. Common techniques includeopen reduction and internal fixation(ORIF), minimally invasive plate osteosynthesis (MIPO), external fixation combined with limited open reduction and internal fixation (EF + LORIF), intramedullary nailing (IMN), and retrograde tibial nailing (RTN). METHODS: PubMed, Embase, Web of Science, and the Cochrane Library were searched through March 19, 2026. Network meta-analysis (R v4.5.1) assessed operation time, fracture healing time, malunion, delayed union/nonunion, and infection, reporting MDs or RRs with 95% CIs. RESULTS: Eleven randomized controlled trials and 18 cohort studies (2145 patients) were included. MIPO was associated with a longer operative time and a longer time to union than IMN-IP (MD = 8.23, 95% CI 0.44-16.01; and MD = 1.02, 95% CI 0.10-1.93, respectively). For malunion, ORIF had a lower risk than MIPO (RR = 0.30, 95% CI 0.11-0.82), whereas MIPO had a higher risk than EF + LORIF (RR = 3.26, 95% CI 1.08-9.80) and IMN-SP (RR = 4.03, 95% CI 1.30-12.48). ORIF, EF + LORIF, and IMN-SP also showed lower malunion risk than IMN-IP. No significant differences were observed for delayed union and nonunion. Infection risk was generally higher with ORIF and MIPO than with several comparators, particularly EF + LORIF and intramedullary nailing-based strategies. CONCLUSIONS: No single strategy was consistently superior. Operation time and impaired union ( delayed union and nonunion) did not differ significantly among techniques. MIPO may be associated with longer time to union than IMN-IP and higher malunion risk than EF + LORIF and IMN-SP. Infection risk appeared higher with ORIF and MIPO in network estimates, although several comparisons remained uncertain. Findings should be interpreted in light of imprecision and study-level heterogeneity. PROTOCOL REGISTRATION: INPLASY2025120055.

Preoperative intramuscular testosterone and urethrocutaneous fistula formation after primary hypospadias repair.

INTRODUCTION: Preoperative androgen stimulation is widely used before hypospadias repair to increase penile dimensions and optimise surgical conditions. However, its impact on postoperative complications, particularly urethrocutaneous fistula formation, remains controversial. OBJECTIVE: To evaluate the association between preoperative intramuscular testosterone therapy and urethrocutaneous fistula formation in children undergoing primary hypospadias repair. STUDY DESIGN: This was a retrospective comparative analysis of prospectively collected clinical data from 111 boys undergoing primary hypospadias repair at a single tertiary pediatric urology center. Patients were divided into two groups: those who did not receive hormonal therapy (Group 1, n = 55) and those who received intramuscular testosterone enanthate (2 mg/kg administered 5 and 2 weeks before surgery; Group 2, n = 56). Preoperative penile measurements, operative characteristics, and postoperative complications were compared. The primary outcome was urethrocutaneous fistula formation. The mean follow-up duration was 11.9 months (median 7 months). RESULTS: Preoperative testosterone therapy was associated with significant increases in glans diameter and stretched penile length at the time of surgery. The hormone-treated group had a significantly higher proportion of proximal hypospadias (p = 0.001), underwent more complex urethroplasty procedures, and had longer operative times (p = 0.007). Postoperative edema and local inflammatory changes were more frequently observed in the hormone-treated group. Despite these differences, urethrocutaneous fistula occurred in four patients in each group (7.3% vs 7.1%, p = 0.357), with no statistically significant difference between groups. DISCUSSION: Despite greater baseline anatomical severity and operative complexity in the hormone-treated group, preoperative testosterone administration was not associated with an increased risk of urethrocutaneous fistula. These findings suggest that improved tissue bulk and vascularity may offset the potential adverse effects of transient inflammatory changes. CONCLUSION: Selective preoperative intramuscular testosterone therapy was not associated with increased urethrocutaneous fistula risk and may be considered a reasonable adjunct in appropriately selected patients undergoing primary hypospadias repair. CLINICAL/TRANSLATIONAL APPLICABILITY: These findings provide clinical reassurance that preoperative testosterone can be used selectively in patients with smaller penile dimensions or anticipated technical difficulty without increasing fistula risk, thereby supporting shared decision-making in clinical practice.

PCa Detection in PI-RADS 4 and 5 Lesions: Comparison of [68Ga]Ga-PSMA-11 PET/CT-Guided Robot-Assisted Biopsy Versus mpMRI Cognitive-Fusion TRUS-Guided Prostate Biopsy.

Lesions with a Prostate Imaging-Reporting and Data System (PI-RADS) score of 4 or greater on multiparametric MRI (mpMRI) indicate a high likelihood of prostate cancer (PCa), and guidelines recommend a targeted biopsy. We aimed to compare the diagnostic performance of robotic arm-assisted [68Ga]Ga-PSMA-11 PET/CT-guided prostate biopsy (PGPB) with mpMRI-directed cognitive-fusion transrectal ultrasound-guided biopsy (MCFB) in biopsy-naïve men with clinical findings suggestive of PCa. Methods: This prospective, single-center, randomized clinical trial (NCT05137561) enrolled biopsy-naïve men age 50-90 y with elevated levels of prostate-specific antigen (≥4 ng/mL) and abnormal digital rectal examination findings. All participants underwent mpMRI, and those with a PI-RADS score of 4 or greater were randomized into 2 arms. In arm 1, participants underwent PGPB for a [68Ga]Ga-PSMA-avid lesion, and participants in arm 2 underwent MCFB. Participants in arm 1 with PET-negative findings subsequently underwent MCFB, and participants with negative biopsy results underwent PET and PGPB. The primary outcome was the detection of PCa. Secondary outcomes included complication rates and participant-reported pain. Result: Of the 267 participants enrolled, 81.3% (217) had lesions with a PI-RADS score of 4 or greater and were randomized to either PGPB (n = 112) or MCFB (n = 105). PCa was detected in 97.1% of participants (101/104) in arm 1 and 81.0% (85/105) in arm 2 (P < 0.05). PGPB showed higher diagnostic accuracy for PI-RADS 5 lesions (100% vs. 95.1%, P = 0.09). Major complications were observed in arm 2 only (n = 5). Arm 1 had significantly fewer complications (10.8% vs. 51.4%, P < 0.01), a lower median visual analog scale score for pain (3 vs. 5), and shorter procedure times. The core positivity rate was higher in arm 1 (60% ± 20%), despite obtaining fewer cores. Conclusion: [68Ga]Ga-PSMA-11 PGPB demonstrated higher diagnostic performance, fewer complications, and better tolerability compared with MCFB. This approach enables integrated diagnosis and staging, offering a promising alternative for efficient, safe, and accurate evaluation of prostate cancer.

Late hiatal hernia after Roux-en-Y gastric bypass: a systematic review.

Obesity is a global public health issue. This condition is linked to gastroesophageal reflux disease (GERD) and hiatal hernia (HH), both of which are exacerbated by increased intra-abdominal pressure. Roux-en-Y gastric bypass (RYGB) is one of the most widely performed techniques for treating obesity and is considered a versatile option suitable for most patients. The development of a symptomatic HH and pouch migration can lead to various symptoms and complications. PubMed, EMBASE, and Cochrane Central were searched for studies with late HH after RYGB. We pooled outcomes for symptom resolution. Secondary outcomes were recurrence rate and operation characteristics (mesh use, cruroplasty, gastropexy, reoperation, length of stay, and operative time). A meta-analysis could not be conducted due to significant heterogeneity in HH. HH following RYGB presents with GERD (39-93.6%), obstructive symptoms (29%-88%), and abdominal pain (28.6%-71%). Diagnostic methods include endoscopy, computed tomography scans, and upper gastrointestinal series. Surgical management varies, with primary cruroplasty being the most common approach, sometimes incorporating mesh or fundoplication. Postoperative symptom resolution rates range from 42.9% to 100%, with HH recurrence occurring in 5%-6.54% of cases. Follow-up durations varied, showing improvement in most patients, though some continued to experience reflux and dysphagia HH contributes to obstructive and reflux symptoms, with contrast-enhanced imaging offering the highest diagnostic accuracy. Bioabsorbable mesh may reduce recurrence, highlighting the need for long-term monitoring.

Retrograde intrarenal surgery with flexible and navigable suction access sheaths vs mini-percutaneous nephrolithotomy for large upper urinary tract stones: a systematic review and meta-analysis.

OBJECTIVE: To conduct a meta-analysis comparing the efficacy and perioperative outcomes of contemporary flexible and navigable suction access sheath-assisted retrograde intrarenal surgery (FANS-RIRS) against percutaneous nephrolithotomy (PCNL) for the management of large upper urinary tract stones, as despite technological advances in RIRS such as high-powered lasers and FANS that have substantially enhanced its performance, current guidelines continue to recommend PCNL as first-line treatment for renal stones >2cm. METHODS: MEDLINE, Embase, and the Cochrane Library were searched for studies performing direct comparisons of FANS-RIRS against PCNL in adult patients until September 2025. Primary outcomes included stone-free rates (SFRs) and need for ancillary procedures. Secondary outcomes included operative time, length of postoperative hospitalisation, and postoperative complications. RESULTS: A total of 10 studies (three randomised control trials, seven retrospective cohort studies) comprising 2347 patients were included; preoperative stone sizes were predominantly 2-3 cm. All PCNL procedures in the studies included were performed as mini-PCNL. The SFRs for FANS-RIRS were comparable with mini-PCNL across all stone sizes (odds ratio [OR] 0.90, 95% confidence interval [CI] 0.70-1.17) and stones ≥2 cm (OR 0.80, 95% CI 0.60-1.08), with low heterogeneity. Ancillary procedures rates were similar (OR 1.22, 95% CI 0.61-2.44). FANS-RIRS was associated with significantly fewer overall complications, specifically smaller haemoglobin decline, need for transfusion, and shorter hospital stay. However, mini-PCNL demonstrated shorter operative times for stones ≥2 cm. Urosepsis rates were low and similar between both groups. Limitations include predominance of Asian studies, variability of practice, and inclusion of non-randomised studies. CONCLUSIONS: Contemporary FANS-RIRS achieves SFRs comparable to mini-PCNL even for 2-3 cm stones, while offering superior safety profiles and shorter hospitalisation; this supports FANS-RIRS as a viable primary treatment in selected patients.

A two-center randomized clinical superiority trial of single-anastomosis sleeve ileal bypass versus sleeve gastrectomy for severe obesity: SASSY study protocol.

BACKGROUND: Single-anastomosis sleeve ileal bypass is a novel metabolic bariatric surgery intended to enhance metabolic outcomes and reduce the risk of postoperative complications. Although preliminary outcome data for single-anastomosis sleeve ileal bypass are promising, evidence from adequately powered, randomized head-to-head comparisons is scarce. This trial compares the efficacy and safety of single-anastomosis sleeve ileal bypass versus sleeve gastrectomy in patients with class II obesity (body mass index = 35.0-39.9 kg/m²) with at least one obesity‑related comorbidity or class III obesity (body mass index ⩾40.0 kg/m²). METHODS: This two-center randomized clinical superiority trial enrolls patients eligible for metabolic bariatric surgery at two specialized Norwegian centers. Included patients are randomly assigned (1:1) to either single-anastomosis sleeve ileal bypass or sleeve gastrectomy with standardized perioperative treatment and care. The primary endpoint is the between-group difference in change in body mass index from baseline to 2 years after single-anastomosis sleeve ileal bypass versus sleeve gastrectomy. Secondary endpoints include additional weight loss outcomes, the prevalence of gastroesophageal reflux disease, surgical and postoperative complications, obesity-related comorbidities, nutritional status, bone mineral density, gastrointestinal symptoms, quality of life, and rates of revisional and conversion surgery. All endpoints will be evaluated at 2 and 5 years after surgery. Statistical analyses utilize linear mixed models and analysis of covariance within an intention-to-treat framework. DISCUSSION: This trial will provide high-level evidence with robust and comparative outcome data on single-anastomosis sleeve ileal bypass and sleeve gastrectomy, aiming to clarify the clinical utility of single-anastomosis sleeve ileal bypass and inform surgical practice. Findings will address gaps in medium- and long-term evidence regarding weight loss, safety, comorbidity resolution, and quality of life following single-anastomosis sleeve ileal bypass.

Single-center experience with isolated male epispadias: Outcomes of Thiersch-Duplay and modified Cantwell-Ransley repairs by anatomical subtype.

BACKGROUND: Isolated male epispadias (IME) is a rare congenital malformation. Surgical repair aims to improve urinary function, correct penile curvature, reconstruct the urethra and glans, and preserve future sexual function. Because available series are small, the influence of anatomical subtype and operative technique on outcome remains incompletely defined. OBJECTIVE: To report single-center outcomes of Thiersch-Duplay and modified Cantwell-Ransley repairs for IME, with attention to anatomical subtype, complications, and age-appropriate continence outcomes. METHODS: We retrospectively reviewed boys with IME who underwent primary urethral reconstruction in my hospital, Capital Medical University, from May 2005 to June 2024. Data were locked on 30 June 2024. Primary outcomes were postoperative complications graded by the Clavien-Dindo system and urinary continence at last follow-up in patients aged 5 years or older. Secondary outcomes included improvement of preoperative incontinence, ICIQ score, subsequent bladder neck reconstruction, penile appearance/residual curvature when documented, and patient/parent-reported sexual function. RESULTS: Sixty-seven patients were included: 35 underwent modified Cantwell-Ransley repair and 32 underwent Thiersch-Duplay repair. The cohort included 26 glanular (38.8%), 23 penile (34.3%), and 18 penopubic (26.9%) cases. Median age at surgery was 28 months in both groups. Median age at last follow-up was 92.8 months (IQR 63.9-108.4) after modified Cantwell-Ransley repair and 137.9 months (IQR 77.9-172.6) after Thiersch-Duplay repair (P = 0.011). Procedure distribution differed by meatal location (P = 0.036), although penopubic cases were treated with both procedures. Total complications occurred in 5/35 and 5/32 patients, respectively. Formal continence analysis included 26 modified Cantwell-Ransley patients and 27 Thiersch-Duplay patients aged 5 years or older. Postoperative urinary incontinence persisted in 14/26 (53.8%) and 12/27 (44.4%), respectively. Among age-eligible patients with preoperative incontinence, any improvement was documented in 13/20 (65.0%) and 14/17 (82.4%), and complete remission occurred in 6/20 (30.0%) and 5/17 (29.4%), respectively. Three patients, all with penopubic epispadias treated with Thiersch-Duplay repair, subsequently underwent bladder neck reconstruction for persistent incontinence. Erectile function data were available in 37/67 patients (55.2%). CONCLUSIONS: In this large single-center retrospective cohort, Thiersch-Duplay and modified Cantwell-Ransley repairs had comparable overall complication rates. Continence and reoperation patterns were strongly influenced by anatomical subtype, with penopubic epispadias representing the highest-risk group. These findings support individualized, anatomy-conscious operative planning and prospective evaluation of standardized selection criteria, rather than a single prescriptive algorithm. CLINICAL/TRANSLATIONAL IMPLICATION: This series supports standardized reporting of anatomical subtype, age-appropriate continence outcomes, and graded complications when counseling families and comparing outcomes across centers. LEVEL OF EVIDENCE: Level III.

Autologous bone grafts versus alloplastic implants for orbital floor reconstruction: a systematic review and meta-analysis.

PURPOSE: The choice of reconstructive material for orbital floor fractures remains a subject of debate. While autologous bone has historically been considered the "gold standard," alloplastic implants offer potential advantages in reducing surgical morbidity. This meta-analysis aimed to compare the safety and efficacy of autologous bone grafts versus alloplastic implants in orbital floor reconstruction. METHODS: A systematic review was conducted in accordance with PRISMA guidelines (PROSPERO: CRD420251140583). Electronic databases (PubMed, Scopus, Web of Science, Cochrane Library) were searched from inception to August 2025. Randomized controlled trials and comparative cohort studies evaluating functional outcomes (diplopia, enophthalmos) and complications (ectropion, infection, malposition) were included. Data were synthesized using a random-effects model, with risk ratios (RR) and 95% confidence intervals (CI) calculated. RESULTS: Twenty studies comprising 2,119 patients were included. Alloplastic implants demonstrated statistically significant superiority in periocular safety, with a reduced risk of postoperative ectropion compared to autologous grafts (RR = 2.245; p = 0.020). In an exploratory sensitivity analysis excluding one outlier study, autologous grafts were associated with a significantly higher risk of implant malposition (RR = 2.074; p = 0.004). Autologous reconstruction was associated with a strong trend toward increased postoperative pain (p = 0.052) and inherent donor-site morbidity. No statistically significant differences were observed regarding infection (p = 0.402), enophthalmos (p = 0.201), or diplopia (p = 0.221). CONCLUSION: Alloplastic implants were associated with a lower risk of ectropion and implant malposition, with functional outcomes statistically comparable to autologous bone. Given the elimination of donor-site morbidity, alloplastic biomaterials represent a safe and effective alternative for orbital floor reconstruction; however, the predominance of retrospective, heterogeneous studies in the current evidence base means these findings should inform, rather than replace, individualized surgical decision-making pending further high-quality randomized trials.
