Laparoscopic Roux-en-Y gastric bypass for morbid obesity.

Surgery is currently the only effective treatment for morbid obesity. The two most commonly accepted operations are the Roux-en-Y gastric bypass and vertical banded gastroplasty.

In this article, we describe our technique of the Roux-en-Y gastric bypass using a laparoscopic approach in four cases.
