Laparoscopic Roux-en-Y Gastric Bypass Versus Laparoscopic Sleeve Gastrectomy
Recruitment status was: Not yet recruiting
The sleeve gastrectomy that has been utilized as a first-stage bariatric procedure to reduce surgical risk in high-risk patients by induction of weight loss is now gaining popularity as a standalone procedure for the treatment of morbid obesity. It appears to be a technically easier and/or faster laparoscopic procedure than Roux-en-Y gastric bypass. It brings good weight loss results, in some studies even comparable to the RYGB and Biliopancreatic Diversion with Duodenal Switch.
The mechanism of action is assumed to be purely restrictive, but some neurohumoral interaction may exist. Almost no data exist on the influence of the sleeve gastrectomy on the medical and general quality of life or resolution of comorbidities.
The rates of the comorbidities resolution 12 to 24 months after sleeve gastrectomy has been reported in the range that seems to be higher than for the purely restrictive procedures.
Our goal is to to compare the surgical and weight loss outcomes between the two procedures, their influence on resolution of common comorbidities and on quality of life change.
150 eligible candidates will be randomized into two groups, one will undergo Laparoscopic Sleeve Gastrectomy, the other will have Laparoscopic Roux-en-Y Gastric Bypass done. Detailed evaluation and preoperative questionnaires will be used to obtain demographic and medical data, and quality of life will be assessed.
General metabolic and nutritional work up will be done, and will be reassessed at different intervals up to 5 years, in order to compare the short and long term results of the two procedures.

Active Comparator: 1
Patients who will undergo Laparoscopic Sleeve Gastrectomy
Procedure: laparoscopic operation Sleeve Gastrectomy
Laparoscopic Sleeve Gastrectomy will be performed employing a 5-6 trocar technique, and includes gastric resection starting 4-5 cm proximal to the pylorus, using a 38 fr. Bougie and endoscopic stapler with blue and green load.
Active Comparator: 2
Patients who will undergo Laparoscopic Roux-en-Y Gastric Bypass
Procedure: laparoscopic operation Roux-en-Y Gastric bypass
Divided LRYGB will employ 5-7 trocars technique, and includes stapled jejunojejunostomy 30-50 cm distal to the Treitz ligament, gastric pouch of 20 cc., and antecolic, antegastric gastrojejunal anastomosis, either two layered hand-sawn, GIA, or EEA-25 -stapled, at surgeons preference. The length of the Roux limb will be 100 centimeters or 150 centimeters in patients with BMI of <50, and >50, respectively.
