Popis: Although the Roux-en-Y gastric bypass (RYGB) is considered a standard procedure, many variations exist in the basic design. In order to achieve more pronounced and sustainable results after RYGB, factors such as diameter of the gastroenterostomy, limb length, and pouch size are gripping points for improvement of design. Extending the pouch could improve results by altering food passage through the pouch. The aim of this randomized controlled trial was to evaluate the effect of an extended pouch RYGB (EP-GB) and standard pouch RYGB (S-GB). In total, 132 patients were randomized in two groups: 68 patients received an EP-GB (pouch length 10 cm) and 64 a S-GB (pouch length 5 cm). Subsequently, weight loss, remission of comorbidities, nutritional status, complications, quality of life, and GERD-symptoms were assessed during a follow-up of 3 years. During the first 2 years of follow-up, no significant differences in terms of weight loss were observed. In the third year of follow-up, the S-GB group regained 3 kg, while in the EP-GB group no weight regain was observed. The mean TBWL after 36 months in the EP-GB group was 31% versus 27% in the S-GB group (p = 0.023). Additionally, besides a better remission rate of hypertension in the EP-GB group, no differences in complications, quality of life, and GERD-symptoms were found. Creation of an extended gastric pouch is a safe and effective modification in RYGB design. An EP-GB improves mid-term weight loss, potentially driven by a lower occurrence of weight regain.
