Introduction: Gastric bypass is one of the most commonly used surgical techniques for the management of morbid obesity. It is usually done as an open surgery procedure, and in recent years surgeons have begun to perform it via the laparoscopic approach. The aim of this paper is to describe our surgical technique for laparoscopic gastric bypass (LGBP) and present the short-term results.

Materials and methods: Between January 2000 and January 2002 we operated on 50 patients with morbid obesity who met criteria for bariatric surgery. The patients had a mean age of 34 years and a body mass index (BMI) of 47.

Results: Conversion was necessary in 4 of the 50 patients (8%). Mean operating time was 181 min, with a difference of 60 min between the first 10 and last 10 cases. There was a 26% rate of complications, 14% of which were early (%<% 30 days) and 12% late (%>%30 days). Mean hospital stay was 4.5 days.

Conclusion: LGBP is a technique with good short-term results as far as weight loss is concerned, although it has one of the most complex learning curves in laparoscopic surgery. Surgeons who regard gastric bypass as the technique of choice for the surgical management of morbid obesity should consider performing it via the laparoscopic approach.
