What is Mini Gastric Bypass Surgery? How is it done?

Mini gastric bypass surgery has emerged as an alternative to gastric bypass surgery and has gained popularity recently. Compared to gastric bypass surgery, it is technically simpler and the operation time is shorter. It has fewer complications from obesity and metabolic surgery operations compared to traditional gastric bypass. It is both an eating-restrictive and malabsorptive surgery.

Technique: The operation is performed under general anesthesia and laparoscopically. Trocars are placed and after carbon dioxide insufflation, an orogastric tube is placed from the mouth to the stomach. Starting from 3-4 cm proximal to the pylorus, a long and thin stomach is prepared. An anastomosis is made to the stomach formed by measuring 200 cm of small intestine from Treitz.
