Gastric Sleeve.

Gastric sleeve surgery or sleeve gastrectomy is an irreversible gastric surgery performed with the intention of reducing weight of the obese gastric sleeve patient. It is a gastric restrictive procedure in which the major portion of the stomach is resected or surgically removed in order to restrict your food intake. This surgery is referred to by many names:

• Vertical sleeve gastrectomy.
• Tube gastrectomy.
• Laproscopic sleeve gastrectomy.
• Gastric sleeve resection.
• Gastric sleeving.

Gastric Sleeve Procedure.

Duration of Surgery: One to two hours.

Anesthesia: General.

Duration of hospital stay: One or two days.

Method of operation. Through laproscope.

The laproscopic method of surgery involves making a few small incisions on the abdomen as against one large incision which is made in an open surgery.

In this procedure, the part of the stomach that is removed also includes major portion of the fundus of the stomach (upper part of the stomach). It is here that the chemical called Ghrelin is produced. Ghrelin is responsible for stimulating appetite. Your appetite therefore gets reduced after this surgery because the fundus of the stomach is reduced.  The surgical changes after this surgery are not reversible. The cut edges are then sutured or stapled with surgical staples.

In this surgery, only the restrictive approach to reduce obesity is performed. The malabsorptive approach is not used. Read Bariatric surgery to know the importance of these two approaches. Major portion of the stomach (about 60% to 80%) is removed and what remains of the stomach is a narrow sleeve.

It forms the first part of weight loss surgery, the second being the gastric bypass or the duodenal switch. This two staged procedure, performed at an interval, becomes necessary to reduce the surgery risks in the extremely obese patients.

The time of the second procedure will be determined by the gastric sleeve surgeon after examining the amount of weight lost. It may be performed anywhere from 6 months to 18 months after the first surgery. The gastric sleeving itself gives a good amount of weight loss, but if weight loss ceases, the second step of the gastric bypass is performed.
