Fibrin sealant versus mechanical stapling for mesh fixation during endoscopic extraperitoneal inguinal hernioplasty: a randomized prospective trial.

OBJECTIVE: To compare the clinical outcome of simultaneous bilateral endoscopic totally extraperitoneal inguinal hernioplasty (TEP) using fibrin sealant (FS) and mechanical stapling for prosthetic mesh fixation. SUMMARY BACKGROUND DATA: Similar efficacy of FS and mechanical stapling for mesh fixation has been demonstrated in a swine model, but no clinical trial has been conducted to compare the outcomes of TEP using these 2 fixation devices. FS adheres the prosthetic mesh without causing injury to the underlying structures. Whether the application of FS improves early postoperative outcomes, namely, reduction of postoperative pain and seroma formation, has not been examined. PATIENTS AND METHODS: Between July 2002 and February 2004, a total of 93 patients with 186 inguinal hernias who underwent bilateral TEP were randomized to have mesh fixation by either FS (n = 46) or mechanical stapling (n = 47). The primary endpoints were severity of pain, analgesic requirement, and incidence of seroma. Secondary endpoints were length of hospital stay, number of days required to resume normal outdoor activities and work, recurrence rate, and incidence of chronic pain. RESULTS: The 2 groups were comparable in age, sex, and types of hernia. TEP were successfully performed in all patients. The FS group consumed significantly less analgesics compared with that of the staple group (P = 0.034). There was no significant difference in the postoperative pain score at rest and on coughing from the day of operation to postoperative day 6 between the groups. The incidence of seroma was significantly higher in the FS group (17.4%) than the staple group (5.3%) (P = 0.009). Length of hospital stay and time taken to resume normal activities and work were comparable between the 2 groups. With a median follow-up of 1.2 years, no recurrent hernia has been detected in either group, but the incidence of chronic pain in the staple group (20.0%) was higher than that of the FS group (13.2%) (P = 0.418). CONCLUSIONS: This randomized prospective clinical trial demonstrated a significant reduction of analgesic consumption by using FS for mesh fixation during bilateral TEP, but it was associated with an increased incidence of postoperative seroma.

A new technique of endoscopic full-thickness resection using a flexible stapler.

There is a significant need for a safe and easy technique for endoluminal endoscopic resection of gastrointestinal lesions, but such procedures are usually restricted to resection of the mucosal layer in order to preserve the integrity of the wall of the gastrointestinal tract. We present two patients, one with early cancer and one with a carcinoid tumor, who were treated by endoscopic full-thickness resection. We used a stapling device, consisting of a flexible shaft, which was positioned intraluminally, and a remote control. After pilot investigations in pigs and in human anatomical preparations, we performed a full-thickness resection of the gastric wall in these patients, using the flexible stapling device under gastroscopic control. Gastric wall specimens up to 4 cm x 4 cm in size were resected with the use of two to three stapler magazines. Both procedures followed an uneventful course and the patients made an uncomplicated recovery. Further studies are necessary to test the applicability of the technique in the management of other gastric neoplastic lesions.

Endoscopic stapling diverticulotomy: an audit of difficulties, outcome, and patient satisfaction.

OBJECTIVE: To evaluate the procedure in terms of technical difficulties, patient satisfaction, symptom relief, recurrence, and further management. STUDY DESIGN: Retrospective study including 41 patients who underwent endoscopic stapling diverticulotomy. Clinical notes were reviewed, and patients were sent a patient satisfaction questionnaire. Statistical analysis was done using the chi(2) square test. SETTING: Teaching hospital. RESULTS: Larger pouches had the best results; 81.578% were satisfied with the surgery, and 86.84% had improved swallowing. Complications presented in 6 patients (15%), including a perforated pouch and an esophageal perforation. Complications were more frequent in small pouches. CONCLUSIONS AND SIGNIFICANCE: Endoscopic stapling diverticulotomy offers rapid recovery in most patients, with early oral intake and short hospital stay. There is a high degree of symptoms relief, and the patient's satisfaction rate is high. The assessment of the pharyngeal pouch size is an important factor when deciding the best management for a patient with a pharyngeal pouch.

Laparoscopic inguinal hernia repair with extraperitoneal double mesh technique.

Extraperitoneal laparoscopic inguinal hernia repair is a technically demanding procedure, with potential injuries to the lateral femoral cutaneous nerve and the inferior epigastric vessels. The double mesh technique developed is designed to address these issues. The procedure is a technical variation to the totally extraperitoneal laparoscopic inguinal hernia repair that avoids stapling in crucial areas and also provides a more secure inguinal floor by adjusting the second mesh to the area of weakness. Over a 20-month period 42 hernias were repaired using this technique that will be described in detail. The results are uniformly excellent with no recurrences documented during the observation period and the method is presented here for consideration in the laparoscopic repair of inguinal hernias.

Laparoscopic ovariopexy before irradiation for medulloblastoma.

Ovarian preservation before abdominal irradiation may be recommended for young patients with various types of invasive cancer. The most common site for ovarian transposition is just below the iliac crest or posterolateral to the uterus. Here, we demonstrate laparoscopic ovariopexy with an automatic stapling device to transpose the ovaries to an uncommon site, i.e. lower anterolateral abdomen, in a patient with medulloblastoma prior to her receiving irradiation of the craniospinal axis. The anterolateral transposition of the ovary not only kept it away from the irradiated field but allowed it also to be shielded by the uterus. Thus, ovarian function could be well preserved.

Vertical banded gastroplasty: first experience in Russia.

BACKGROUND: The first experience of vertical banded gastroplasty (VBG) in the Russian National Research Center of Surgery is presented. METHODS: From November 1992 to October 1996, 24 morbidly obese patients (mean body weight 147.7 kg, BMI 52.1 kg/m2) underwent VBG according to Mason. RESULTS: The early complication rate was 20.8%. The mean excess weight loss (EWL) after weight stabilization (first 12 patients) was 48.0% in the whole group and 53.9% (range 36.0-73.0%) in 10 patients without staple-line disruptions. Significant positive changes in obesity related diseases were noted. Nine of 23 patients presented with incisional hernias some months after operation. CONCLUSION: The impression of VBG is favorable; however, gaining further experience with the standard techniques and increasing the long-term results are necessary.

Modified double-stapling technique in low anterior resection for lower rectal carcinoma.

PURPOSE: The original double-stapling technique (DST) using a standard linear stapler horizontally can be difficult in patients with a narrow pelvis or an ultralow anastomosis. We review our experience of performing a modified DST (IO-DST) with vertical division of the rectum achieved using an endostapler. METHODS: We retrospectively studied the clinical outcomes of 90 patients who underwent low anterior resection (LAR) for lower rectal carcinoma. Low anterior resection was performed with IO-DST in 34 patients (IO-DST group), with the single-stapling technique (SST) in 47 (SST group), and with per anal anastomosis (PAA) in 9 (PAA group). RESULTS: The distances from the anal verge to the tumor and to the anastomosis were significantly shorter in the IO-DST group than in the SST group (5.8 cm, 4.0 cm vs 7.0 cm, 5.0 cm, respectively), whereas it was equivalent in the IO-DST and PAA groups (5.0 cm, 4.0 cm). Blood loss was less in the IO-DST group than in the SST and PAA groups (400 ml vs 578 ml and 950 ml, respectively). The operative time was shorter in the IO-DST group than in the PAA group (281 min vs 327 min, respectively). There were no significant differences in the length of the distal surgical margin among the three groups. The IO-DST group patients suffered less bowel frequency than the SST group patients 1 month after surgery (2.5 times/day vs 4.0 times/day, respectively) and less than the PAA group patients more than 1 year after surgery (2.0 times/day vs 3.5 times/day, respectively). There were no significant differences in the incidence of complications or local recurrence among the three groups. CONCLUSIONS: IO-DST is a feasible and safe procedure for performing low anastomosis, which results in less bowel frequency after LAR for lower rectal carcinoma.

Reasons for early recurrence following laparoscopic hernioplasty.

The incidence and reasons for early recurrences following laparoscopic hernioplasty have not been studied. Because the incidence is small and the follow up is short, a multi-institutional study was performed among the pioneers in the field. The incidence figures were obtained by survey of surgeons who had significant experience (over 100 cases) and kept concurrent records. Fifty-four recurrences (1.7%) occurred after 3229 laparoscopic hernia repairs. There were 1944 transabdominal preperitoneal (TAPP) repairs with 19 recurrences (1%) and 578 preperitoneal repairs with no recurrences. There were 345 onlay mesh (IPOM) repairs with seven recurrences (2%), and 286 plug and patch repairs with 26 recurrences (9%). Simple closures were performed 76 times with two recurrences (2.6%). Fifty-seven patients (three cases were referred to the author without incidence data but complete records for analysis) had 60 recurrent hernias. Recurrences were noted, on average, 5.1 months postoperatively (range 0-30 months). The most common reason for recurrence was that the mesh was too small - 36 (60%). The mesh was never stapled in 19 instances (32%), and the hernia was never repaired in three cases (20%). The clips pulled through the tissue in six cases (8%), and in 10 cases (15%) the repair has not yet been undertaken because the etiology was unclear. There was more than one reason in 19 patients. Technical factors were responsible for nearly all recurrences.

Triple arthrodesis: a biomechanical evaluation of screw versus staple fixation.

The subtalar, talonavicular, and calcaneocuboid joints were internally fixed to simulate triple arthrodesis was performed on eight matched pairs of human cadaver feet. Feet were randomly assigned such that one specimen in each pair was internally fixed with cobalt-chrome staples and one specimen with stainless steel screws. Liquid metal strain gauges were placed in a perpendicular fashion across the three joints of each specimen. Each foot was then secured to the Shore Western Materials Test System where a series of 10 increasing eversion stresses across the foot was created. Displacement was measured at each joint with every increase in eversion stress. Our results show that there is no statistical difference in fixation strength between screws and staples at the talonavicular, calcaneocuboid, or subtalar joints (P = 0.862). Although many studies determining the strength to failure of different implants have been performed, shear stress and micromotion at the joint surfaces have not been evaluated, to our knowledge, and no single implant in this study has shown superior immobilization characteristics to recommend its use as the implant of choice in triple arthrodesis.

Early experience with computer-mediated flexible circular stapling technique for upper gastrointestinal anastomosis.

BACKGROUND: Creating the proximal anastomosis in laparoscopic biliopancreatic diversion with duodenal switch (LBPD-DS) and Roux-en-Y gastric bypass (LRYGBP) is a critical step in ensuring the success of the procedures. The aim of this study was to assess the safety and efficiency of performing this anastomosis using a flexible, computerized, circular stapling device. METHOD: We prospectively monitored the use of a newly FDA-approved stapling device (SurgASSIST, Power Medical Intervention) for the construction of the proximal anastomosis by a variety of approaches and reviewed the charts of 10 patients. RESULTS: We successfully constructed 9 out of 10 proximal anastomoses: 2 gastro-jejunostomies and 7 duodeno-ileostomies, without any signs of leakage. In 2 patients, the stapling technique involved a transpyloric instrumental passage; both were complicated by the difficulty to pass either the flexible scope or the anvil through the narrow pyloric lumen. In 5 patients, the anvil was placed directly through a duodenotomy and no technical problems were encountered. The median time for performing the proximal anastomosis was 19 minutes (range 9-55). There were no postoperative complications in any patients. CONCLUSIONS: Stapling using the SurgASSIST was feasible and safe for performing laparoscopic anastomoses in bariatric bypass procedures. A duodenotomy for direct placement of the anvil into the postpyloric region seems to be most feasible for duodenoileostomies, while transoral passage of the anvil can be recommended for gastro-jejunostomies. In its current form, we do not recommend transoral placement of the flexible shaft of the SurgASSIST device. Further clinical trials need to be performed for comparison with existing devices.

[Emergency resections of the left colon with immediate reconstruction protected by resorbable staples. A new possibility tested on animals].

Anastomosis recovery still represents a problem in colon surgery, particularly when the resection is performed in emergency or on a suffering and not adequately prepared bowel. The authors describe a new technique successfully tested in the animal. The operation consists in a bowel resection followed by immediate reconstruction with a protective colostomy and an exclusion anastomosis obtained by a proximal suture in resorbable clips. Results in animals have been satisfactory, with a spontaneous and gradual resumption of physiological canalization, according to authors expectations. Technical details and several histological features are herein described.

Epiphysiodesis in juvenile hallux abducto valgus. A preliminary retrospective study.

Juvenile hallux abducto valgus manifested prior to physeal plate closure was treated by lateral epiphyseal stapling and modified McBride bunionectomy in nine children (15 feet) from 1984 to 1992. The prevalent preoperative symptoms were significantly reduced postoperatively. The intermetatarsal angle decreased an average of 6.6 degrees (initial decrease was 2.7 degrees with an additional 3.9 degrees occurring over time). The hallux abducto valgus angle decreased an average of 19.6 degrees (initial decrease was 10.7 degrees with an additional 8.9 degrees occurring over time).

Stapled ileoanal pouches without loop ileostomy: a prospective study in 86 patients.

In restorative proctocolectomy the use of a stapling technique to construct an ileal pouch with anal anastomosis offers an alternative to the hand-sewn technique following mucosectomy; a temporary defunctioning loop ileostomy may reduce the consequences of an anastomotic leakage, however it may entail discomfort for the patient, an additional operation, possible complications, and longer total hospital stay. This prospective study evaluated the peri- and postoperative courses in 86 consecutive, referred patients receiving ileal pouch-anal anastomosis using the stapling technique to construct the ileal pouch and ileoanal anastomosis, omitting the defunctioning loop ileostomy except in cases of increased risk of ileoanal anastomotic insufficiency according to defined criteria. Follow-up time was 36-96 months. Patients undergoing primary loop ileostomy stayed a median of 19 days in hospital, as opposed to a median of 9 days in those who did not. Eight patients developed pelvic sepsis that demanded a secondary defunctioning loop ileostomy, and five showed symptoms arising from relapsing inflammation in residual rectal mucosa; in three of these, a secondary transanal mucosectomy covered by a loop ileostomy was necessary. During the follow-up period ten patients had bowel obstructions that demanded surgery; two developed late pouch-vaginal fistulas, and one a fistula from the J-limb to the abdominal scar. There was one case of pouch procidentia. At 12-month follow-up the median evacuation frequency was 6 per 24 h, the incidence of minor incontinence was about 10%, and urgency to evacuate occurred in about 10%. None of the patients experienced any major incontinence. The stapling technique and omission of the defunctioning loop ileostomy in restorative proctocolectomy were thus a comparatively reliable and time-saving method with short total hospital stay. In patients at increased risk of anastomotic complications, however, a defunctioning loop ileostomy is recommended. We believe it is important to perform an exact dissection into the anal canal to avoid a residual rectal mucosa that may be inflamed or even become dysplastic.

Consensus conference on the stapled transanal rectal resection (STARR) for disordered defaecation.

An international working party was convened in Rome, Italy on 16-17 June, 2005, with the purpose of developing a consensus on the application of the circular stapling instrument to the treatment of certain rectal conditions, the so-called Stapled Transanal Rectal Resection (STARR). Since the procedure has been submitted to only limited objective analysis it was felt prudent to hold a meeting of interested individuals for the purpose of evaluating the current status and to make conclusions and recommendations concerning the applicability of this new approach.

Rate and treatment of pelvic recurrence after abdominoperineal resection and low anterior resection for rectal cancer.

PURPOSE: This study was designed to analyze factors of importance for local recurrence after radical surgery for rectal cancer and to analyze course and outcome of treatment of pelvic recurrence. METHODS: One hundred seventy-five patients treated for rectal cancer with low anterior resection (LAR) or abdominoperineal resection (APR) were studied, retrospectively. Seventy-four patients had LAR and 101 had APR. RESULTS: The two groups were comparable with respect to Dukes classification, histologic differentiation, and male to female ratio. The rate of pelvic recurrence was 18 percent for LAR and 24 percent for APR (not significant). Recurrence rates were 27 percent after stapled anastomoses and 10 percent after handsewn anastomoses respectively (P = 0.09). Twenty five had pelvic recurrence diagnosed without signs of distant metastatic disease. They were treated with radiotherapy, palliative operations, or analgesics. The group receiving radiotherapy had a significantly longer survival (15.9 months) compared with other groups (2.4 months; P < 0.001). CONCLUSIONS: There is no difference in local recurrence rate after LAR and APR. Radiotherapy seems to increase survival in patients with an unresectable recurrence and should be offered irrespective of pain.

Dynamic assist splinting for attenuated sagittal bands in the rheumatoid hand.

The extensor mechanism of the hand is complex, requiring effective functioning of all involved structures, including the sagittal bands. The sagittal bands function to maintain the extensor tendons in midline and to limit their distal excursion. Injury to the sagittal bands or sagittal band attenuation can cause instability and ulnar displacement/subluxation of the extensor tendons into the valleys between the digits and lead to a subsequent loss of active finger extension at the metacarpophalangeal joints. Secondary conditions may also develop, such as swan-neck deformity, as is frequently observed in the rheumatoid arthritis population. To prevent or reduce an extension lag and secondary changes and to maintain the functional use of the hand, a dynamic metacarpophalangeal extension assist splint is necessary. This splint enables extension at the metacarpophalangeal joints, thus enabling the functional use of the hand. This article reviews the biomechanics of the sagittal bands and the corrections that enable finger extension at the metacarpophalangeal joints, thus preventing secondary conditions.

Stapled hemorrhoidopexy vs. Harmonic Scalpel hemorrhoidectomy: a randomized trial.

PURPOSE: A randomized trial was undertaken to evaluate and compare stapled hemorrhoidopexy with excisional hemorrhoidectomy in which the Harmonic Scalpel was used. METHODS: Patients with Grade III hemorrhoids who were employed during the trial period were recruited and randomized into two groups: (1) Harmonic Scalpel hemorrhoidectomy, and (2) stapled hemorrhoidopexy. All operations were performed by a single surgeon. In the stapled group, the doughnut obtained was sent for histopathologic examination to determine whether smooth muscles were included in the specimen. Operative data and complications were recorded, and patients were followed up through a structured pro forma protocol. An independent assessor was assigned to obtain postoperative pain scores and satisfaction scores at six-month follow-up. Patients were also administered a simple questionnaire at follow-up to assess continence functions. RESULTS: Over a 20-month period, 88 patients were recruited. The two groups were matched for age and gender distribution. No significant difference was identified between the two groups in terms of operation time, blood loss, day of first bowel movement after surgery, and complication rates. Despite a similar parenteral and oral analgesic requirement, the stapled group had a significantly better pain score (P = 0.002); these patients also had a significantly shorter length of stay (P = 0.02), and on average resumed work nine days earlier than the group treated with the Harmonic Scalpel (6.7 vs. 15.6, P = 0.002). Although 88 percent of doughnuts obtained in the stapled group contained some smooth muscle fibers, no association was found between smooth muscle incorporation and postoperative continence function, and as a whole the continence outcomes of the stapled group were similar to those after Harmonic Scalpel hemorrhoidectomy. Finally, at six-month follow-up, patients who underwent the stapled procedure had significantly better satisfaction scores (P = 0.001). CONCLUSION: Stapled hemorrhoidopexy is a safe and effective procedure for Grade III hemorrhoidal disease. Patients derive greater short-term benefits of reduced pain, shorter length of stay, and earlier resumption to work. Long-term follow-up is necessary to determine whether these initial results are lasting.

Long-term clinico-radiological assessment of endoscopic stapling of pharyngeal pouch: a series of cases.

The endoscopic division of the pharyngeal pouch wall with a mechanical stapling device has become increasingly popular. When compared to open excision, the reduced operative time, early resumption of oral intake, and short in-patient stay with no early recurrence of symptoms, are the proposed advantages. Small pouches or thick walled pouches are not suitable for stapling. From December 1996 to December 1999, 32 patients were admitted to the Aberdeen Royal Infirmary for endoscopic stapling of a pharyngeal pouch. Five patients were unsuitable for stapling. In addition, three patients were treated for pouch recurrence after an external approach. Two patients required repeat stapling at a later date. Our results are encouraging in terms of short operation time and hospital admission, improvement of symptoms and minimal complication rate. Fifteen patients were assessed 24 months after the procedure with satisfaction surveys and contrast swallow X-rays. Subjective improvement was sustained throughout this period, despite radiological evidence of persistence of the pharyngeal pouch.
