Is simultaneous hepatectomy and intestinal anastomosis safe?

BACKGROUND: To assess the safety of simultaneous, "one-stage," hepatectomy and intestinal anastomosis, we retrospectively studied 53 patients who underwent such a procedure, with 76 digestive tract sutures. They represented 80% of all the cases eligible for one-stage procedures among 332 liver resections for malignant tumors. METHODS: The medical records of the patients were retrospectively analyzed to assess details of the surgical procedures, postoperative mortality and morbidity, and postoperative liver function, with special attention being paid to the prothrombin time and the bilirubin value on days 1, 2, 3, and 7. RESULTS: No postoperative mortality occurred and the postoperative morbidity rate was 19%. Only 2 cases of digestive tract anastomotic leakage occurred, which led to reoperation. Hepatectomy-related complications were noted in 5 patients (3 biliary fistulas, 1 hemorrhage and 1 transient liver failure), and pulmonary infections occurred 3 times. The technical difficulties of the one-stage procedure are discussed, focusing on the choice of the incision, the risk of sepsis for the liver if there is an intestinal aperture, possible repercussions of liver impairment and hepatic pedicle clamping on bowel suture healing, and the risk of digestive fistula according to the location of the bowel suture. CONCLUSION: It appears that this one-stage procedure is safe if the bowel is systematically cleaned before the operation, if an appropriate Rio-Branco incision is used, and if the risk of postoperative liver failure is low. It seems preferable to use intermittent hepatic pedicle clamping rather than continuous clamping (when feasible), and to temporarily protect a low rectal anastomosis with a colostomy.

[Prediction of postoperative visual acuity in retinal detachment with macular involvement].

We used laser interferometry (LI) and a potential acuity meter (PAM) to predict visual acuity after surgery for patients with rhegmatogenous retinal detachment with macular involvement. Thirty one eyes of 31 patients with retinal detachment were treated with scleral buckling procedures. Postoperative visual acuity was correlated with preoperative measurements of the LI and PAM, preoperative visual acuity by Landort's ring, and the estimated duration of macular detachment. The correlation between the duration of macular detachment and the postoperative visual acuity was not good (r = 0.55, p < 0.01). Although the preoperative visual acuity showed a relatively good correlation with postoperative visual acuity (r = 0.62, p < 0.01), the results of the LI and PAM provided a better correlation (LI; r = 0.73, PAM; r = 0.71). Our results suggest that the LI and PAM are useful to predict the visual acuity after retinal reattachment in patients with preoperative macular detachment.

"Threshold-level" multipulse transcranial electrical stimulation of motor cortex for intraoperative monitoring of spinal motor tracts: description of method and comparison to somatosensory evoked potential monitoring.

UNLABELLED: Numerous methods have been pursued to evaluate function in central motor pathways during surgery in the anesthetized patient. At this time, no standard has emerged, possibly because each of the methods described to date requires some degree of compromise and/or lacks sensitivity. OBJECT: The goal of this study was to develop and evaluate a protocol for intraoperative monitoring of spinal motor conduction that: 1) is safe; 2) is sensitive and specific to motor pathways; 3) provides immediate feedback; 4) is compatible with anesthesia requirements; 5) allows monitoring of spontaneous and/or nerve root stimulus-evoked electromyography; 6) requires little or no involvement of the surgical team; and 7) requires limited equipment beyond that routinely used for somatosensory evoked potential (SSEP) monitoring. Using a multipulse electrical stimulator designed for transcranial applications, the authors have developed a protocol that they term "threshold-level" multipulse transcranial electrical stimulation (TES). METHODS: Patients considered at high risk for postoperative deficit were studied. After anesthesia had been induced and the patient positioned, but prior to incision, "baseline" measures of SSEPs were obtained as well as the minimum (that is, threshold-level) TES voltage needed to evoke a motor response from each of the muscles being monitored. A brief, high-frequency pulse train (three pulses; 2-msec interpulse interval) was used for TES in all cases. Data (latency and amplitude for SSEP; threshold voltage for TES) were collected at different times throughout the surgical procedure. Postoperative neurological status, as judged by evaluation of sensory and motor status, was compared with intraoperative SSEP and TES findings for determination of the sensitivity and specificity of each electrophysiological monitoring technique. Of the 34 patients enrolled, 32 demonstrated TES-evoked responses in muscles innervated at levels caudal to the lesion when examined after anesthesia induction and positioning but prior to incision (that is, baseline). In contrast, baseline SSEPs could be resolved in only 25 of the 34 patients. During surgery, significant changes in SSEP waveforms were noted in 12 of these 25 patients, and 10 patients demonstrated changes in TES thresholds. Fifteen patients experienced varying degrees and durations of postoperative neurological deficit. Intraoperative changes in TES thresholds accurately predicted each instance of postoperative motor weakness without error, but failed to predict four instances of postoperative sensory deficit. Intraoperative SSEP monitoring was not 100% accurate in predicting postoperative sensory status and failed to predict five instances of postoperative motor deficit. As a result of intraoperative TES findings, the surgical plan was altered or otherwise influenced in six patients (roughly 15% of the sample population), possibly limiting the extent of postoperative motor deficit experienced by these patients. CONCLUSIONS: This novel method for intraoperative monitoring of spinal motor conduction appears to meet all of the goals outlined above. Although the risk of postoperative motor deficit is relatively low for the majority of spine surgeries (for example, a simple disc), high-risk procedures, such as tumor resection, correction of vascular abnormalities, and correction of major deformities, should benefit from the virtually immediate and accurate knowledge of spinal motor conduction provided by this new monitoring approach.

Is postoperative haematoma an avoidable complication of intracranial surgery?

Postoperative intracranial haematoma is a serious complication of intracranial surgery with a mortality rate of around 30%. There have been reports implicating abrupt rises of blood pressure during the last stages or immediately after the procedure, in the production of the clot. This prospective study examined this hypothesis. Over the last 7 years, 526 consecutive patients underwent craniotomy under a strict anaesthesiological protocol based on deep opioid analgesia which virtually eliminated any acute elevations of the arterial pressure during and immediately after craniotomy. Emergence from anaesthesia was delayed for an average of 1 1/2-2 h following the procedure. Postoperative CT was obtained in every patient. There have been no cases of postoperative clot formation in this series of patients. The results of the study suggest that postoperative haematoma is probably an avoidable complication of intracranial surgery.

Prospective multicentre randomised trial of tension-free vaginal tape and colposuspension as primary treatment for stress incontinence.

OBJECTIVE: To compare tension-free vaginal tape with colposuspension as primary treatment for stress incontinence. DESIGN: Multicentred randomised comparative trial. SETTING: Gynaecology or urology departments in 14 centres in the United Kingdom and Eire, including university teaching hospitals and district general hospitals. PARTICIPANTS: 344 women with urodynamic stress incontinence; 175 randomised to tension-free vaginal tape and 169 to colposuspension MAIN OUTCOME MEASURES: Assessment before treatment and at six months postoperatively with the SF-36, the Bristol female lower urinary tract symptoms questionnaire, the EQ-5D health questionnaire, a one week urinary diary, one hour perineal pad test, cystometry, and, in some centres, urethral profilometry. RESULTS: 23 women in the colposuspension group and 5 in the vaginal tape group withdrew before surgery. No significant difference was found between the groups for cure rates: 115 (66%) women in the vaginal tape group and 97 (57%) in the colposuspension group were objectively cured (95% confidence interval for difference in cure -4.7% to 21.3%). Bladder injury was more common during the vaginal tape procedure; postoperative complications, in particular delayed resumption of micturition, were more common after colposuspension. Operation time, duration of hospital stay, and return to normal activity were all longer after colposuspension than after the vaginal tape procedure. CONCLUSION: Surgery with tension-free vaginal tape is associated with more operative complications than colposuspension, but colposuspension is associated with more postoperative complications and longer recovery. Vaginal tape shows promise for the treatment of urodynamic stress incontinence because of minimal access and rapid recovery times; cure rates at six months were comparable with colposuspension.

A prospective, longitudinal study of nonconventional strictureplasty in Crohn's disease.

BACKGROUND: Bowel-sparing techniques have been proposed to avoid extended or repeated resections in patients with Crohn'rsquo;s disease (CD), but without precise indications, prospective evaluation, and with a technically limited repertoire. STUDY DESIGN: A prospective longitudinal study of new nonconventional strictureplasties (NCSP) in order to evaluate the safety, type and site of recurrence, and longterm clinical and surgical efficacy. RESULTS: Between January 1993 and December 2002, 102 among 305 consecutive patients underwent at least one NCSP for complicated CD. Patients were treated following precise indications and then included in a prospective database with scheduled followup. Factors claimed to influence postoperative and longterm outcomes and type and site of recurrence were analyzed. We performed 48 ileoileal side-to-side isoperistaltic strictureplasty (SP), 41 widening ileocolic SP, 32 ileocolic side-to-side isoperistaltic SP, associated with Heineke-Mikulicz SP (in 80 procedures) or with minimal bowel resections or both (in 47 procedures). Postoperative mortality was nil; complication rate was 5.7%. Ten years clinical and surgical recurrence rates were 43% and 27%, respectively. Recurrence rate on an NCSP site was 0.8%. No specific factor was identified as related to postoperative or longterm outcomes. CONCLUSIONS: Perioperative and longterm results of NCSP are comparable to or even better than both conservative and resective surgery as reported in the literature, with a low recurrence rate on the NCSP site. Considering the unpredictability of the clinical course of CD and the lifetime need for surgical procedures, NCSP, together with minimal resection and classic SP repertoire, should be considered first-line treatment in complicated CD.

Treatment of postoperative ureteral stricture by catheter dilation: a forgotten procedure.

Some postoperative ureteral strictures can be managed successfully by simple catheter dilations as shown in the cases presented herein. It appears that only one or two dilations may be necessary for prolonged resolution of the obstructive process. Internal ureteral splints may be used with equally good results. Operating intervention should be reserved for those cases in which either ureteral catheterization cannot be accomplished or dense fibrosis renders adequate long-term management by catheter dilation impossible.

Superficialis finger reconstruction: a new look at a last-resort procedure.

The anatomic two-tendon, three-joint finger cannot always be restored to normal after a severe flexor tendon injury. An effective alternative to consider is reconstruction of superficialis finger function or one-tendon to two-joint function. This principle has been applied to two-stage flexor tendon reconstruction in severe salvage situations to provide a good working arc of digital flexion. The surgical procedure, postoperative considerations, and biomechanical principles are discussed.

[Differentiated thyroid cancers. Etiopathogenic and clinical data, prognostic factors and surgical treatment].

Thyroid cancer is the most common among endocrine malignant neoplasm. The cause of its grow is as well the external factors influence and primary malfunction of thyroid cells. The most common is papillary cancer but in the regions where iodine level is low the incidence of follicular cancer increases. The postoperative procedures depend on the type and stage of cancer. Nowadays centers which deal with thyroid cancer treatment are for primary radical surgery as it is followed by lower possibility of missing the cancer in the thyroid remnant, easier postoperative follow up and supplementary treatment management.

Ropivacaine compared to lidocaine for tonsillectomy under local anaesthesia.

The aim of the present study was to investigate the safety and efficacy of ropivacaine compared to lidocaine for tonsillectomy under local anaesthesia. During the last 2 years, 77 patients undergoing tonsillectomy under local anaesthesia in the seated position were randomised to receive ropivacaine or lidocaine. The following parameters were recorded: time to surgical anaesthesia, the duration of the procedure, postoperative pain, the need for analgesics during the first 10 h after surgery, cardiac arrhythmias, the occurrence of allergic reaction and larynx spasm. It took significantly longer to reach surgical anaesthesia in the ropivacaine patients (8.3+/-1.3 min versus 2.7+/-0.8 min.), but the pain immediately following the procedure was significantly lower (1.0+/-0.4 versus 2.6+/-1.0). Adjuvant analgetics were administered later and in significantly lower doses in the ropivacaine patients. There were no adverse reactions. In conclusion, ropivacaine in local tonsillectomy is safe, has a longer onset-time, but is more efficient concerning postoperative pain than lidocaine.

Experience with Damus procedure.

Sixteen patients with complex cyanotic congenital heart disease underwent an operation involving the use of the aorta and the main pulmonary artery as the egress for systemic arterial blood flow (the Damus-Kaye-Stansell operation, modified as discussed). The indication for this approach was either preoperative aortic outlet obstruction or likelihood that the repair would produce such obstruction. A modification of the original technique is introduced that involves transection of both great arteries, anastomosis of the contiguous aortic and pulmonic walls, and connection of the distal aorta to the perimeter of the new (bivalved) great artery. Eleven of the 16 patients survived operation: six of six who underwent a concurrent Fontan operation, four of six who underwent a concurrent right-ventricle-to-pulmonary-artery-conduit procedure, and one of four who underwent a concurrent systemic-pulmonary shunt procedure. Postoperative status in the 11 survivors is good: one patient has a gradient from the left ventricle to the aorta, 10 of 11 have little or no aortic regurgitation, and the remaining patients have a normal physiological status. We conclude that the Damus procedure is a useful addition to the surgical armamentarium for treatment of certain types of cyanotic congenital heart disease.

[Hospital ambulatory pediatric surgery].

Since 1990, we have been conducting ambulatory pediatric surgery in an unit established solely for this purpose, supported by a team of kindergarten teachers, pediatric nurses, anesthesiologists and pediatric surgeons. This prospective investigation includes all ambulatory pediatric operations performed in our department from 1990 to 1995. In this time 3665 infants and children between the ages of 6 weeks and 18 years underwent an ambulatory operation. The ratio male to female was 4.1 to 1. The series consists of 1400 inguinal hernias, 722 inguinal testes, 191 hydroceles/funiculoceles, 75 umbilical hernias, 667 phimoses, 70 meatotomies, 59 hemangiomas, 217 endoscopies and 264 other surgical procedures. Postoperative complications defined as secondary hemorrhage, fever, obvious vomiting, urine retention and laryngospasm upon terminating anesthesia accompanied by subsequent vomiting occurred in 59 (1.6%) of all infants and children. Wound infections were seen in 0.48% (17/3517) of all patients. The recurrence rate for inguinal hernias were 0.79% and 1.12% for inguinal testes. Our experience enables us to summarize that a variety of pediatric operations can be performed today as ambulatory procedures. Nevertheless one must be prepared for the occurrence of complications and always have capacities free for inpatient care where adequate observation and treatment are available. Further improvement is necessary in quality management. In the last 20 years only a few data have been published about recurrence rates after pediatric ambulatory operations for inguinal hernias and inguinal testes. Therefore we started a prospective long- term study.

Intramedullary nailing of proximal quarter tibial fractures.

OBJECTIVE: To report the results of intramedullary nailing of proximal quarter tibial fractures with special emphasis on techniques of reduction. DESIGN: Retrospective clinical study. SETTING: Level 1 trauma center. PATIENTS: During a 36-month period, 456 patients with fractures of the tibial shaft (OTA type 42) or proximal tibial metaphysis (OTA type 41A2, 41A3, and 41C2) were treated operatively at a level 1 trauma center. Thirty-five patients with 37 fractures were treated primarily with intramedullary nailing of their proximal quarter tibial fractures and formed the study group. Thirteen fractures (35.1%) were open and 22 fractures (59.5%) had segmental comminution. Three fractures had proximal intraarticular extensions. MAIN OUTCOME MEASUREMENTS: Alignment and reduction postoperatively and at healing. An angular malreduction was defined as greater than 5 degrees in any plane. RESULTS: Fractures extended proximally to an average of 17% of the tibial length (range, 4% to 25%). The average distance from the proximal articular surface to the fracture was 67.8 mm (range, 17 mm to 102 mm, not corrected for distance magnification, included for preoperative planning purposes only). Postoperative angulation was satisfactory (average coronal and sagittal plane deformity of less than 1 degree) as was the final angulation. Acceptable alignment was obtained in 34 of 37 fractures (91.9%). Two patients had 5-degree coronal plane deformities (one varus and one valgus), and 1 patient had a 7-degree varus deformity. Two patients with open fractures with associated bone loss underwent a planned, staged iliac crest autograft procedure postoperatively. Four patients were lost to follow-up. In the remaining 31 patients with 33 fractures, the proximal tibial fractures united without additional procedures. No patient had any change in alignment at final radiographic evaluation. Secondary procedures to obtain union at the distal fracture in segmental injuries included dynamizations (n = 3) and exchange nailing (n = 1). Complications included deep infections in 2 patients that were successfully treated. CONCLUSIONS: Multiple techniques were required to obtain and maintain reduction prior to nailing and included attention to the proper starting point, the use of unicortical plates, and the use of a femoral distractor applied to the tibia. Simple articular fractures and extensions were not a contraindication to intramedullary fixation. The proximal tibial fracture healed despite open manipulations. Short plate fixations to maintain this difficult reduction, either temporary or permanent, were effective.

Postoperative pain in neurosurgery: a pilot study in brain surgery.

The incidence, magnitude, and duration of acute pain experienced by neurosurgical patients after various brain operations are not precisely known, because of a lack of well-designed clinical and epidemiological studies. We assessed these important pain variables in 37 consecutive patients who underwent various brain neurosurgical procedures. Postoperative pain was more common than generally assumed (60%). In two-thirds of the patients with postoperative pain, the intensity was moderate to severe. Pain most frequently occurred within the first 48 hours after surgery, but a significant number of patients endured pain for longer periods. Pain was predominantly superficial (86%), suggesting somatic rather than visceral origin and possibly involving pericranial muscles and soft tissues. Subtemporal and suboccipital surgical routes yielded the highest incidence of postoperative pain. Age and sex were significantly associated with the onset of pain, with female and younger patients reporting higher percentages of postoperative pain. Psychological Minnesota Multiphasic Personality Inventory profiles of patients with and without pain significantly differed on the Hypochondriasis scale, with patients without pain scoring unexpectedly higher than patients with pain. It is possible that hypochondriasis serves as a defense mechanism against pain, at least in some patients. Results of this pilot study indicate that postoperative pain after brain surgery is an important, although neglected, clinical problem, that deserves greater attention by surgical teams, to provide better and more appropriate treatment.

Continuous cold therapy in total knee arthroplasty.

This article describes a retrospective study that assessed 52 consecutive patients who underwent total knee arthroplasty (TKA) between January 1, 1992 and September 15, 1992. Thirty-three patients underwent TKA and received cold therapy pads placed over a thin dressing in the operating room. Nineteen patients underwent TKA using an identical operative and postoperative procedure, but did not receive continuous cold therapy. Continuous cold therapy consisted of two sterile plastic pads connnected by rubber hoses containing cool water from an electric main unit that maintained a constant temperature of 42 degrees F for the immediate postoperative period. Cold therapy pads were used an average of 3 days and removed with the first dressing change. Patients who had continuous cold therapy averaged a 200 cc decrease in postoperative blood loss. There was no significant difference in the amount of narcotic use, transfusion requirements, or hospital stay between the two groups. Postoperative swelling and range of motion were not consistently recorded. Twenty-eight other variables also examined not significant. Based on these results, we cannot recommend continuous cold therapy or justify the extra expense for all patients who undergo TKA.

Appendiceal carcinoma: patterns of failure following surgery and implications for adjuvant therapy.

BACKGROUND AND OBJECTIVES: Primary adenocarcinoma of the appendix is rare, which makes an understanding of its natural history difficult. To date, it is treated predominantly with surgery alone. This review aims to elucidate the patterns of failure and treatment outcomes when adjuvant treatment is given after primary surgical resection. METHODS: Twenty-three patients were treated with either surgery alone, or with surgery and adjuvant radiation +/- chemotherapy. A review of the clinical course of these patients was undertaken with an analysis of the local control, distant failure, disease-free survival, and overall survival. RESULTS: Most patients presented with local invasion or metastatic disease often involving the peritoneum. Overall survival was 32%, similar to the results of other studies. Analysis of patients with locally advanced disease showed improvement in overall survival and local control with postoperative radiation therapy compared to surgery alone. CONCLUSIONS: Adenocarcinoma of the appendix is a rare disease that presents most often in an advanced stage. It has been shown by others that a right hemicolectomy provides the best outcome with respect to surgical procedure. Postoperative irradiation appears to provide a benefit for both local control and overall survival.

Pubovaginal sling using polypropylene mesh and Vesica bone anchors.

OBJECTIVES: To report preliminary results from a modified pubovaginal sling procedure using polypropylene mesh as the sling suspended by nonabsorbable sutures anchored to the pubic tubercle with Vesica bone anchors. METHODS: Thirty-five women with type III stress urinary incontinence (SUI) (with or without associated urethral hypermobility) or type II SUI with additional risk factors such as obesity, chronic obstructive pulmonary disease, or failed prior incontinence-correcting procedures underwent this modified pubovaginal sling procedure. Postoperative voiding status was evaluated during office follow-up visits and telephone surveys. RESULTS: With a mean follow-up of 8.4 months (range 2 to 18), 32 women (91.4%) were dry, 1 improved, and 2 remained incontinent. The pubovaginal sling procedure was the only operation performed in 46% of patients, with a mean operative time of 72 minutes, a mean estimated blood loss of 137 mL, and a mean hospital period of 2.3 days. Patients on whom concomitant gynecologic procedures were performed had a mean duration of surgery of 122 minutes, a mean estimated blood loss of 202 mL, and a mean hospitalization period of 2.9 days. Thirteen women had preoperative urgency that persisted in 31% of patients. De novo urgency developed in 3 patients. Seven women required prolonged suprapubic tube drainage but no patient remained in permanent retention. There has been no infection or erosion. CONCLUSIONS: Our experience with this modified pubovaginal sling procedure using polypropylene mesh and Vesica bone anchors showed excellent results with greater technical ease, minimal morbidity, and decreased hospitalization period when compared to a traditional pubovaginal sling performed in our hands. Additional follow-up will be needed to assess long-term efficacy.

Bioactive prosthetic material for treatment of hernias.

HYPOTHESIS: Laparoscopic herniorrhaphy using Surgisis (Cook Surgical, Bloomington, IN, USA) mesh is an effective long-term treatment for repair of inguinal hernia. PATIENTS AND INTERVENTION: Between August 1999 and April 2005, 67 patients underwent laparoscopic inguinal hernia repair by the total extraperitoneal (TEP) mesh placement technique using Surgisis mesh. A total of 82 primary direct, indirect, pantaloon, and femoral hernias were repaired using this technique. MAIN OUTCOME MEASURES: Postoperative complications and recurrence as evaluated at two weeks, six weeks, three months, six months, one year, and yearly thereafter for up to five years. RESULTS: The operations were performed successfully on all the patients. One revision was done to an open procedure. Postoperative complications were typical of inguinal hernia surgery. Average follow up was 38 (range: 4-72, median: 35 months. Four non-technical recurrences following repair of direct hernias were reported, which indicates a 4.9% recurrence rate. No recurrences of indirect hernias were noted. CONCLUSIONS: Laparoscopic inguinal herniorrhaphy using Surgisis mesh is effective in treatment of primary inguinal hernias in adults with minimal complications and recurrence up to five years of follow up.
