Laparoscopic surgery has many advantages over the open procedure, such as minimal scarring, less chances of wound infections, fewer days of hospital stay, and low incidence of incisional hernia.

This pouch is connected to the central part of the small intestine. Therefore, the food bypasses the remainder of the abdomen and the upper part of the small intestine.

Normally, food passes through the abdomen and enters the primary part of the small intestine called the duodenum. The stomach acts as the reservoir. That means, after the food is eaten, it is stored in the stomach. The food gets mixed with digestive fluids and slowly released into the small intestine where most of the food gets digested and absorbed.
