[Laparoscopic stomach bypass surgery].

Obesity is rapidly becoming a major medical problem in the developed world. Surgery is the only treatment with proven long-term efficiency for morbid obesity. We claim this surgery should be done by laparoscopy, because it is less invasive and morbidity is relatively low in obese patients, who are by definition fragile. Jejunojejunostomy can be performed by different techniques: side-to-side semimechanical, side-to-side entirely mechanical, end-to-side hand-sewn, and side-to-side hand-sewn. Gastrojejunostomy can be performed by different techniques: circular mechanical anastomosis with the anvil inserted through the mouth, gastrostomy, linear mechanical anastomosis, or hand-sewn anastomosis. We report our technique of laparoscopic gastric bypass with different possibilities for the two anastomoses.
