Mini gastric bypass

The mini gastric bypass, also known as the omega-loop or one-anastomosis bypass, is a variant of the classic bypass. It combines the creation of an elongated gastric pouch with a single connection (anastomosis) to the intestine, compared with two for the Roux-en-Y bypass. The technique is therefore simpler and the operating time shorter, with comparable effectiveness in terms of weight loss. Like other bariatric procedures, it acts both on meal volume and on the hormonal mechanisms that regulate hunger and metabolism. It is particularly suitable for certain patient profiles, with the choice discussed case by case with the multidisciplinary team. The mini bypass is performed entirely by laparoscopy and, like the classic bypass, requires vitamin supplementation and regular long-term medical and nutritional follow-up. At Clinique Pasteur Tunis, the mini gastric bypass is part of the full range of bariatric techniques on offer, making it possible to recommend to each patient the procedure best suited to their situation, within a coordinated care pathway.
