Background: Surgery is the only effective treatment for morbid obesity. Gastric bypass could fail in up to 10% of the patients (excess weight loss under 50%).
Aims: To evaluate the weight loss determined by reoperation performing disabsortive variation of gastric bypass.
Patients and methods: The records of 41 patients, in whom 32 were submitted to reoperation by one of three surgical techniques (Fobi, Brolin, distal gastrojejunoileal bypass) which consisted in increasing the disabsortive length of intestinal limb.
Results: The patients submitted to distal gastrojejunoileal bypass showed the best results (69.7%).
Conclusion: The distal gastric bypass as a revisional procedure could be done in selected cases with the aim to improve the weight loss. It is advisable to refer these patients to selected centers (known as center of excellence) with experience in this area of bariatric surgery, in order to perform a very close follow-up.
