BACKGROUND The first global survey of bariatric/metabolic surgery based on data from the nations or national groupings of the International Federation for the Surgery of Obesity and Metabolic Diseases (IFSO) was published in 1998, followed by reports in 2003, 2009, 2011, and 2012. In this survey, we report a global overview of worldwide bariatric surgery in(More)
After a successful trial of bilio-pancreatic bypass in dogs, a clinical study has been completed in 18 patients followed for more than 1 year. The operation has been modified to achieve the best weight reduction, and forming the bilio-pancreatic tract of equal length to the alimentary tract with a short common ileal tract, the average weight loss as a(More)
Biliopancreatic diversion (BPD) has made reacceptable the malabsorptive approach to the surgical treatment of obesity. The procedure, in a series of 2241 patients operated on during a 21-year period, caused a mean permanent reduction of about 75% of the initial excess weight. The indefinite weight maintenance appears to be due to the existence of a(More)
BACKGROUND Surgical attempts to treat obesity began because of the discouraging results of conservative medical treatment, which successfully achieved initial weight loss but failed to maintain it. Gastric restrictive procedures, currently the most popular surgical methods for obesity therapy, have proved to be effective in initiating weight loss, but some(More)
Bilio-pancreatic bypass is a new procedure that tries to obtain a maldigestion syndrome with selective malabsorption of the main high calorie foods. The operation consists of a gastric resection and division of the proximal jejunum just distal to the ligament of Treitz. A gastroentero-anastomosis is then constructed using the distal end of the transected(More)
In 2005, for the first time in European history, an extraordinary expert panel named BSCG (Bariatric Scientific Collaborative Group), was appointed through joint effort of the major European scientific societies which are active in the field of obesity management. Societies that constituted this panel were: IFSO - International Federation for the Surgery of(More)
The treatment of obesity by intestinal bypass provides a unique model for the investigation of gut hormone release from the functionally deranged bowel. We have examined the postprandial response of eight circulating gut or pancreatic peptide hormones in 16 preoperative obese patients, 20 patients with jejunoileal bypass, 38 patients with biliopancreatic(More)
