Sleeve gastrectomy surgery procedure

Sleeve gastrectomy surgery by the laparoscopic method is performed under the general anesthesia and it take time less than one hour. The procedure is as the following:

Complete anesthesia and create needed incision

After complete anesthesia, three to five small incisions are created on abdominal wall. Trocars are placed in these incision as a passageway for surgical instruments. Trocar is a surgical instrument with a cutting point enclosed in a tube that is used in surgery for access to the blood vessel and body holes.

Filling stomach by carbon dioxide gas

Stomach is filled by the carbon dioxide gas in order to lift the stomach wall away from the inside stomach structure. The surgeon uses a laparoscope (a tube with light and camera) to watch the stomach hole. After that, the surgeon uses a retractor to lift up the liver of the stomach in order to create enough room for surgeon to see behind the stomach.

The stomach separation from long intestine and spleen

The vessels and greater curvature ligaments, the fibrin tissue, that connect stomach to the spleen, stomach and large intestine, are divided. The stomach is fully separated from spleen and intestines. The entire underside of the stomach shouldn’t be connecting to the left crus of the diaphragm structures that attach the diaphragm to the vertebral column. The blood vessel of left side of the stomach and left branch of the vagus nerves left untouched.

Dividing the stomach to create a gastric tube

A sizing device called a bougie is then placed into the pyloric channel. The thick antrum or cavity of the stomach is divided by cutting transversely around the bougie to create a gastric tube.

Stapling the length of the gastric tube

A gastric sleeve is a pouch with an estimated capacity of less than 150 ml. Stapling along the length of the stomach that formed by the bougie creates a narrow tube. The staple line may be covered with material that is meant to reduce the risk of bleeding and/or leaks.

Removing the resected stomach

The resected stomach is placed in a specimen bag and then extracted through the trocar site. The port sites are then closed with non-absorbable sutures to prevent port site hernia.

Laparoscopic sleeve gastrectomy with duodenal switch

Duodenal switch procedure applies as the second surgery phase for patients who couldn’t lose much weight after several months of laparoscopic sleeve gastrectomy.

Along the duodenal switch, the small intestine, that is attached naturally to the stomach, is divided into two parts to create a pathway. Naturally, the digestive loop, takes food from the stomach to the entrance of small intestine; but after the switch, foods shift to the lower portion of the small intestine.
