LGB appeared promising during the first few years after its introduction, but results worsen over time, despite improvements in the operative technique and material. Only about 60% of the patients without major complication maintain an acceptable EWL in the long term. Each year adds 3-4% to the major complication rate, which contributes to the total failure rate. With a nearly 40% 5-year failure rate, and a 43% 7-year success rate (EWL >50%), LGB should no longer be considered as the procedure of choice for obesity. Until reliable selection criteria for patients at low risk for long-term complications are developed, other longer lasting procedures should be used.

Except in the setting of acute obstruction, clinical and radiological findings usually do not help in the diagnosis of internal hernia. A high index of suspicion, based mainly on the clinical history of recurrent colicky abdominal pain, is the only means to reduce the number of acute complications leading to bowel resection by offering the patient an elective laparoscopic exploration with repair of all the defects. Prevention by carefully closing all potential mesenteric defects with running non-absorbable sutures during laparoscopic RYGBP, which we consider mandatory, seems appropriate in reducing the incidence of this complication.

Background: Bariatric surgery is often associated with reduced food tolerance and sometimes frequent vomiting, which influence quality of life, but are not included in the overall evaluation of these procedures, notably the BAROS. Our aim was to develop a simple questionnaire to evaluate food tolerance during follow-up visits.Methods: A one-page questionnaire including questions about overall satisfaction regarding quality of alimentation, timing of eating over the day, tolerance to several types of food, and frequency of vomiting/regurgitation was developed. A composite score was derived from this questionnaire, giving a score of 1 to 27. Validation was performed with a group of nonobese adults and a group of morbidly obese nonoperated patients. Patients were administered the questionnaire at follow-up visits since January 1999. Data were collected prospectively.Results: It takes 1-2 minutes to fill out the questionnaire. Food tolerance is worse in the morbidly obese population compared with non-obese adults (24.2 vs 25.2, P=0.004). Following Roux-en-Y gastric bypass, food tolerance is reduced after 3 months (21.2), but becomes comparable to that of the normal population and remains so at 1 year postoperatively. Following gastric banding, food tolerance is already significantly reduced after 3 months (22.3), and worsens continuously over time (19.03 after 7 years). In the gastric banding population, the decision to adjust the band is based at least partially on food tolerance, and the questionnaire proved helpful in that respect.Conclusions: Our new questionnaire proved very easy to use, and helpful in day-to-day practice, especially after gastric banding. It was also helpful in comparing food tolerance over time after surgery, and in comparing food tolerance between procedures. Evaluation of food tolerance should be part of the overall evaluation of the results after bariatric surgery.

These results are satisfactory and comparable to those reported from the USA. Owing to limitations associated with purely restrictive bariatric procedures, laparoscopic RYGBP is likely to become the procedure of choice for treatment of morbid obesity in Europe.
