Stricture rate after laparoscopic Roux-en-Y Gastric bypass with a 21-mm circular stapler: the Cleveland Clinic experience.

OBJECTIVE: The objectives of this study were to report the incidence of gastrojejunal anastomic strictures that occurred in laparoscopic Roux-en-Y gastric bypass (LRYGB) surgery and to determine the time course of presentation, associated perioperative factors, and response to balloon dilation. SUBJECTS AND METHODS: All 126 patients who underwent LRYGB at the Cleveland Clinic Foundation between July 2003 and February 2005 were included. We utilized a transoral 21-mm circular stapler for the gastrojejunostomy. Patients with symptoms of anastomotic strictures underwent upper endoscopy by one surgeon (B.C.). A stricture was defined by the inability to pass a 10-mm gastroscope through the anastomosis. Balloon dilation was performed to 12 mm. Records were analyzed retrospectively and statistical analysis including Pearson chi(2) statistics, Fisher's exact test and Student's t test were used when appropriate. RESULTS: Symptomatic anastomotic strictures occurred in 29 (23%) patients. All patients presented with nausea, vomiting and dysphagia. The median time to diagnosis was 52 days (25-309 days). Symptoms resolved after one dilation in 25 (86%) of patients. Two and three dilations were required in 1 (3.5%) and 3 (10.5%) of patients, respectively. No patients had complications or required more than 3 dilations. Age, preoperative body mass index (BMI), and intraoperative blood loss did not correlate with stricture formation. Although nonsteroidal anti-inflammatory drugs were used by 46 (41%) of patients after surgery, there was no correlation with stricture formation. CONCLUSION: Symptomatic anastomotic strictures developed in nearly a quarter of patients who underwent LRYGB utilizing a transoral 21-mm circular stapled gastrojejunal anastomosis. A single endoscopic balloon dilation was usually adequate. Strictures were not predicted by perioperative factors.

Laparoscopic resection for Crohn's disease: an experience with 335 cases.

BACKGROUND: Laparoscopic resection for Crohn's disease has had a slow adoption rate in gastrointestinal surgery. This is not unexpected considering the inflammatory nature of the disease, the need for reoperative surgery, and the presence of fistulas. The authors review their experience with 335 laparoscopic resections for Crohn's disease over the past 15 years. METHODS: This study is a retrospective analysis of a prospective database from one surgeon at the Mount Sinai Hospital, New York, NY. RESULTS: Since 1993, 335 patients with Crohn's disease in the current series have undergone laparoscopic resection. The mean age of the patients was 39 years, and 54% of the patients were women. In most cases, the indication for surgery was intestinal obstruction (73%) or abdominal pain (16%). The most common operation was primary ileocolic resection, performed for 178 cases (49%). Secondary ileocolic resections were performed for 20% and small bowel resections for 11% of the cases. Of the 117 patients with enteric fistulas, 45% had multiple fistulas. There were 80 enteroenteric, 51 ileosigmoid, 33 enteroabdominal wall, and 22 ileovesical fistulas. Multiple resections were performed for 33 patients (9%). Eight conversions occurred (2%), primarily because of large inflammatory masses involving the intestinal mesentery. The mean length of hospital stay was 5 days, and the mean operative time was 177 min (range, 62-400 min). There were no mortalities. The complications were primarily bowel obstruction, anastamotic leak, and postoperative bleeding, resulting in a postoperative complication rate of 13%. CONCLUSION: This review summarizes the largest series of laparoscopic resection for Crohn's disease to date. The most common operation performed was ileocolic resection. Fistulous disease is common, but it is not a contraindication to laparoscopic resection. These cases can be managed safely and with acceptable morbidity in experienced hands.

Erosion of gastric electrical stimulator electrodes: evaluation, management, and laparoscopic techniques.

BACKGROUND AND OBJECTIVE: Gastric electrical stimulation is a promising technology for treatment of gastroparesis. Few studies address potential complications of the device. MATERIALS: We review the diagnosis and laparoscopic management of 2 cases of gastric stimulator (GS) electrode erosion through the gastric wall. RESULTS: Both patients presented with late (16 and 21 mo) device infection. Diagnosis of electrode erosion was verified by upper endoscopy. The electrodes were successfully removed laparoscopically. A new GS and electrodes were implanted laparoscopically in 1 patient 6 months later. CONCLUSIONS: Electrode erosion is an unusual complication. Surgeons must have a high index of suspicion for electrode erosion when patients present with late GS infections. Eroded electrodes can be removed and replaced laparoscopically.

The effects of acute preoperative weight loss on laparoscopic Roux-en-Y gastric bypass.

BACKGROUND: Minimal acute pre-operative weight loss significantly reduces liver size and intra-abdominal adipose tissue. We hypothesize that these changes will reduce intra-operative complications and reduce the difficulty of laparoscopic Roux-en-Y gastric bypass (LRYGBP). METHODS: This is a retrospective chart review of consecutive patients who had undergone isolated LRYGBP between July 2003 and March 2005. All patients participated in our institution's medically supervised Weight Management Program before surgery. RESULTS: 48 patients (Weight Loss Group) had an average percent loss of excess weight (%EWL) of 4.6; whereas 47 patients (No Weight Loss Group) gained an average of 4.8% of excess weight over an average period of 2.4 and 3 months (P=0.09), respectively. There were no differences between the two groups in age, gender, ASA class, co-morbidities, or BMI at operation. The Weight Loss Group had less intra-operative blood loss (102 vs 72 ml, P=.03). The surgeon was also less likely to report an enlarged liver in the Weight Loss Group (P=.02). Finally, the operation was less likely to deviate from the standard LRYGBP when patients lost weight (P=.02). No differences were seen in operative time, length of hospital stay, wound infections, or major complications. CONCLUSION: Acute preoperative weight loss is associated with less intra-operative blood loss and reduces the need for intraoperative deviation from the standard LRYGBP. A larger series with a greater reduction in excess weight is necessary to determine the maximal benefits of acute preoperative weight loss.
