Combined laparoscopic/endoscopic anvil placement for the performance of the gastroenterostomy.

Background: We developed the laparoscopic gastric bypass in 1993 and first reported the technique and results in 1994. The technique for the gastroenterostomy was derived from the method used in the percutaneous endoscopic gastrostomy tube placement. Some have questioned the safety of this technique, and alternatives have been proposed.

Laparoscopic gastric bypass, Roux-en-Y- 500 patients: technique and results, with 3-60 month follow-up.

Background: The authors have performed the laparoscopic gastric bypass since 1993 and perform about one-half of bariatric cases laparoscopically. Since our initial report, several groups throughout the world have preformed the gastric bypass laparoscopically, with various modifications.

Method: Prospectively, we followed and recorded the results of our laparoscopic patients.

Pregnancy following gastric bypass for morbid obesity.

Background: Women who suffer from morbid obesity are often infertile. If these women are able to become pregnant, they are considered high risk because of the hypertension, diabetes and other associated risk factors. Following the pregnancy is difficult due to limitations of the physical examinations.
