The laparoscopic management of benign bowel fistulas.

BACKGROUND: The presence of a fistula has usually been a factor predicting high conversion and complication rates following laparoscopic procedures for Crohn's disease and diverticulitis. METHODS: We studied retrospective data collected from the medical case notes of patients. A single surgeon carried out all these procedures from 1991 through 2001. RESULTS: Fourteen patients underwent 15 procedures. Six patients were males and 8 were females. The diagnosis was Crohn's disease in 10 patients and diverticulitis in 4. In 10 cases, the operation was the primary procedure, but 5 procedures were for recurrences. Two patients with diverticulitis and 3 with Crohn's disease had only the fistulae divided with the application of an Endo-GIA stapier across the fistulae (stapled fistulectomy). No bowel resections were carried out in these 5 patients. Four cases had to be converted due to bleeding (23%). The only postoperative complication was a single case of wound infection after conversion. CONCLUSION: The presence of a fistula isn't necessarily an indication for conversion. If it is possible to dissect the loops free, we believe that a stapled fistulectomy is effective with a low incidence of fistula recurrence, especially in Crohn's disease.

Long-term experience with endoscopic staple-assisted esophagodiverticulostomy for Zenker's diverticulum.

The authors have previously described the endoscopic staple-assisted esophagodiverticulostomy (ESED) technique for treatment of Zenker's diverticulum. In the initial series of six patients, ESED was shown to be safe and effective in the short term, with a significant reduction in hospital stay and convalescence as compared with other surgical techniques. This report documents the authors' long-term experience with ESED (average follow-up, 9.3 months; range, 1.5 to 25 months) and discusses the long-term results of this therapy, technical issues, and variations they have utilized, as well as the advantages and limitations of this approach. Thirty-six patients with Zenker's diverticula have been treated from March 1995 to March 1997. In 34 of the patients, ESED was accomplished, resulting in successful resolution of preoperative symptoms in 32 (94%). Two patients had persistent dysphagia after initial ESED; a revision ESED was successfully performed without complication in both. Two patients were unable to be treated with ESED because of inability to expose the diverticulum with the Weerda laryngoscope. Oral liquid diet has been resumed, on average, 0.8 days after surgery (range, 0 to 4 days), with solid diet resumed by day 5 (range, 1 to 14 days). The average hospital stay has been 1.3 days (range, 1 to 4 days). There have been no postoperative deaths, infections, or airway difficulties. Perioperative morbidity to date has included one case of iatrogenic pharyngeal perforation, one postoperative fever, one transient true vocal fold paralysis, and two dental injuries, with no long-term sequelae. The results support the use of ESED as the initial treatment of choice for patients with Zenker's diverticula.

Randomized trial to determine the optimum level of pouch-anal anastomosis in stapled restorative proctocolectomy.

PURPOSE: This study was undertaken to identify the optimum level of stapled ileal pouch-anal anastomosis. METHOD: A prospective, randomized trial was completed to compare double-stapled ileoanal anastomosis placed at the top of anal columns (high, n = 26) with anastomosis at the dentate line (low, n = 21). RESULTS: There was no significant difference in the overall complication rate between operations (high, n = 7, vs. low, n = 8; P < 0.21). Pouch-anal functional score (scale 0-12; 0 = excellent, 12 = poor) was significantly better in the high anastomosis group (median (range): 2 (1-9) vs. 5.5 (1-12); P < 0.05). Incontinence occurred in only two patients randomized to high anastomosis compared with six in the low anastomosis group. Nocturnal soiling was reported in three patients after high anastomosis and in six patients after dentate line anastomosis. Both operations caused a significant but comparable reduction of maximum and resting pressure (31 percent after high anastomosis (P < 0.05); 23 percent after low anastomosis (P < 0.05)). However, a significant fall in functional length of the anal canal was only seen after a low pouch-anal anastomosis (P < 0.05). CONCLUSION: Stapled pouch-anal anastomosis at the top of anal columns gives better functional results compared with a stapled anastomosis at the dentate line.

Loop ileostomy closure after restorative proctocolectomy: outcome in 1,504 patients.

PURPOSE: Routine use of a temporary loop ileostomy for diversion after restorative proctocolectomy is controversial because of reported morbidity associated with its creation and closure. This study intended to review our experience with loop ileostomy closure after restorative proctocolectomy and determine the complication rates. In addition, complication rates between handsewn and stapled closures were compared. METHODS: Our Department Pelvic Pouch Database was queried and charts reviewed for all patients who had ileostomy closure after restorative proctocolectomy from August 1983 to March 2002. RESULTS: A total of 1,504 patients underwent ileostomy closure after restorative proctocolectomy during a 19-year period. The median length of hospitalization was three (range, 1-40) days and the overall complication rate was 11.4 percent. Complications included small-bowel obstruction (6.4 percent), wound infection (1.5 percent), abdominal septic complications (1 percent), and enterocutaneous fistulas (0.6 percent). Handsewn closure was performed in 1,278 patients (85 percent) and stapled closure in 226 (15 percent). No significant differences in complication rates and length of hospitalization were found between handsewn and stapled closure techniques. CONCLUSIONS: Our results demonstrated that ileostomy closure after restorative proctocolectomy can be achieved with a low morbidity and a short hospitalization stay. In addition, we found that complication rates and length of hospitalization were similar between handsewn and stapled closures.

The use of taped skin closure in orthopaedic wounds.

The cosmetic result, cost effectiveness, and complication rate of three different types of skin closure: staples, tapes, and interrupted nylon were compared. In 68 wounds, skin closure was randomized to staples, tapes, or interrupted 3/0 nylon sutures. All wounds were closed subcutaneously with interrupted undyed 2/0 dexon. For 3 months, 59 wounds were followed and assessed by an independent observer at 1 and 3 months postoperatively in the outpatient department. In three different skin closures, the cosmetic result was superior for tapes because the wound line itself was finer and there were no dot scars. Tapes were the most cost-effective because they are the cheapest although they were not as quick to apply as staples. There was no difference in complication rate. Tapes also afforded the greatest patient comfort.

Stapled anopexy for short segment Hirschprungs disease in adults.

Traditional treatment of short segment Hirschprungs disease in adult consists of major resectional procedures, often with the use of a temporary stoma. Patients with this disease may have significant morbidities that increase their risk of post-operative morbidity and mortality. In an attempt to minimize the procedural related morbidity, we describe the application of the stapled anopexy technique to treat short segment Hirschprungs disease.

In vitro evaluation of an inverted end-to-end equine jejunojejunal anastomosis using skin staples.

OBJECTIVE: To compare functional indices of end-to-end (EEA) jejunojejunal anastomosis using skin staples in horses with a 2-layer inverting hand-sewn technique. STUDY DESIGN: Experimental study. SAMPLE POPULATION: Jejunal segments from 8 fresh equine cadavers. METHODS: For each bowel segment, 2 EEA anastomoses were created: one 2-layer hand-sewn and one 1-layer using skin staples. Time for anastomosis creation was recorded and compared. Lumen diameter of each anastomosis was measured on digital radiographs after intraluminal instillation of contrast medium and inflation of the jejunal segments to 14 mm Hg. Anastomotic indices (a compensated measure of stoma diameter) and bursting pressure were determined. RESULTS: EEA jejunal anastomosis using skin staples was significantly faster than use of a 2-layer hand-sewn technique. Anastomotic index, a measure of lumen size, was significantly larger with the skin-staple technique; however, the bursting pressure of stapled anastomoses was significantly less than for the hand-sewn technique, but the values were well above those reported for other anastomotic techniques. CONCLUSIONS: An anastomotic technique using skin staples was easy to learn and perform, effective and faster, and mechanically comparable with a hand-sewn 2-layer technique. CLINICAL RELEVANCE: The staple technique could be beneficial in equine gastrointestinal surgery by reducing anastomosis time, although further in vivo studies are needed to establish clinical safety.

Fixation methods in mandibular reconstruction using fibula grafts: a comparative study into the relative strength of three different types of osteosynthesis.

BACKGROUND: Bone staples made of a nickel titanium alloy exert dynamic compression, require little dissection, and may provide an alternative to conventional fixation in mandibular reconstruction with a free vascularized fibula graft. METHODS: To evaluate its stability relative to conventional methods of fixation with interosseous wires or miniplates, an in vitro model using beech dowels was developed. Torsional stiffness and strength and compression stiffness and strength were examined. RESULTS: The compression test results showed that maximum strength of interosseous wires is significantly less than memory staples, which in turn are significantly weaker than titanium miniplates. Miniplates are significantly the most rigid form of fixation. Torsional testing showed no significant difference in strength between staples and miniplates and only a marginal difference in elasticity. Interosseous wires show a rapid decrease of strength and rigidity during torsional stress. CONCLUSION: When considering interosseous wires the least and miniplates the most stable form of fixation by which bone healing can occur, memory staples can provide enough stability to ensure consolidation.

Dixon's anastomosis with "double-stapling" technique: experience with 235 cases.

The perioperative results of 235 Dixon's anastomoses performed between 1985 and 1994 are compared to those of 125 Dixon's anastomoses performed between 1956 and 1979, on the basis of recurrences and survival data. It is concluded that the operations carried out with double stapling are considerably superior interventions with respect to speed, sterility and anastomotic safety and involve less complications. There is no difference between the stapling and handsewn techniques concerning the development of local recurrences. A further advantage of stapling is that it makes possible the saving of the sphincter more often, namely in almost 50% of the cases.

Laparoscopic paravaginal repair: a new technique using mesh and staples.

OBJECTIVE: To describe a new technique of paravaginal repair, utilizing Prolene mesh and a hernia stapler. METHODS: We conducted a retrospective case series review of 12 patients who underwent laparoscopic bladder neck suspension, who were clinically diagnosed with cystocele caused by paravaginal defects. The patients had paravaginal repair performed utilizing mesh and staples. Prolene mesh was stapled to the vaginal margin and suspended from Cooper's ligament. The technique is described and demonstrated in a line drawing. RESULTS: All procedures were completed without incident. No additional blood loss or other morbidity has been identified. Results were evaluated by history and examination. Subjective improvement was noted in 10 of 11 patients. Objective improvement was found in 9 of 11. Adverse effects were not identified. One patient was lost to follow-up. CONCLUSION: This procedure is potentially an alternative method for performing the paravaginal repair by a minimally invasive route. We feel that this makes the procedure potentially safer, quicker, and more accessible to laparoscopic surgeons but with equal effectiveness. Larger series with more rigorous analysis are required before the procedure can be evaluated adequately and recommended for general use.

Staple line reinforcement with new biomaterial increased burst strength pressure: an animal study.

BACKGROUND: Most bariatric operations rely on stapler devices. Although today staplers are extremely safe, efficient, and reliable, a potential risk exists for staple line failures, leading to three complications: leaks, fistulas, and bleeding. Porcine small intestinal submucosa strip applied over the staple line suture might help prevent these problems. METHODS: Forty animals (canine model developed at the University of São Paulo, São Paulo, Brazil) underwent general anesthesia and laparotomy. One nonreinforced staple line suture and one staple line suture reinforced with Surgisis SLR was created in each animal. The burst strength pressure of the 80 staple line sutures was obtained. Suture line bleeding and the ease of use of the membrane were also noted. The data were compared (Student's t test). The dogs were euthanized after the procedure. Two surgeons with experience in stapler devices performed all procedures. RESULTS: The mean +/- SD burst pressure was 209.26 +/- 76.41 mm Hg and 441.33 +/- 128.64 mm Hg for the stapler line without and with the biodegradable membrane, respectively. The difference was statistically significant (P = .002). No in vivo suture line bleeding occurred. The biodegradable membrane was easy to use. CONCLUSION: The biodegradable membrane was able to increase the burst strength pressure of the bowel segment staple line. It might help prevent some causes of staple line leaks.

Intraluminal migration of bovine pericardial strips used to reinforce the gastric staple-line in laparoscopic bariatric surgery.

A 41-year-old morbidly obese woman (BMI 40.8) underwent elective laparoscopic biliopancreatic diversion with duodenal switch. The operation involved: sleeve gastrectomy, division of duodenum, creation of a duodenoenterostomy, and creation of a distal ileoenteric anastomosis. With laparoscopic stapling, bleeding is often a problem along the sleeve gastrectomy staple-line. To reduce this risk, we used bovine pericardial strips to reinforce the staple-line throughout its length. 4 weeks postoperatively, the patient was found to have fragments of pericardium in her vomitus, indicating intraluminal migration of the reinforcing strips. Her subsequent course has been uneventful. This represents the first report of such migration. Indications, benefits, complications and risks of using bovine pericardium to reinforce gastric staple-lines in laparoscopic bariatric surgery are discussed.

[Alternative use of the EEA stapler in subtotal esophagectomy].

Authors describe the successful usage of EEA stapling by reconstruction after subtotal oesophagectomy of carcinoma in the middle third of oesophagus. EEA stapling was pushed in transorally and oesophagogastric anastomosis was made. Neither pre- or post-operative complications occurred by this procedure. Patient left the hospital on 14th day afer the operation. Authors consider transoral application of EEA stapling as effective alternative in creation of oesophagogastric anastomosis after subtotal oesophagectomy.

Handsewn vs. stapled anastomoses in colon and rectal surgery: a meta-analysis.

PURPOSE: Trials comparing handsewn with stapled anastomoses in colon and rectal surgery have not found statistical differences. Despite this, authors have differed in their conclusions as to which technique is superior. To help determine whether differences in patient outcomes are present, a meta-analysis of all trials was performed. METHOD: A meta-analysis of all randomized, controlled trials assessing handsewn and stapled colon and rectal anastomoses was done using a fixed-effects model. Outcome variables were mortality, technical problems, leak rates, wound infections, strictures, and cancer recurrence. Outcomes were assessed for all anastomoses involving the colon and for the subset of colorectal anastomoses. RESULTS: Thirteen distinct trials met the inclusion criteria. Intraoperative technical problems were more likely to occur with stapled than with handsewn anastomoses for all anastomoses (P < 0.0001) and for colorectal anastomoses (P < 0.001). Strictures were also more common following stapled anastomoses (P = 0.015 for all anastomoses; P = 0.028 for colorectal anastomoses). All other outcome measures, including mortality, clinical and radiologic leak rates, and local cancer recurrence rates showed no difference between groups. CONCLUSION: Although intraoperative technical problems and postoperative strictures were more common with stapled anastomoses, other outcome measures showed no difference between groups. Thus, both techniques are effective, and the choice may be based on personal preference.
