What is Sleeve Gastrectomy?

Sleeve gastrectomy is a surgical weight-loss procedure generally done by laparoscopy where the stomach is reduced to about 25% of their original size. By laparoscopic surgery removal of a large area of the stomach is done , following a major curve. Outer edges stomach are then attached together often with surgical staples to create a sleeve or tube having a banana shape. The process permanently reduces the size the stomach. The procedure is performed laparoscopically and isn't reversible.

Sleeve gastrectomy is also called gastric sleeve is usually performed on extremely obese patients with BMI more than 35 - 40. This procedure is more popular nowadays because the chance of performing a gastric bypass or duodenal switch procedure might be too large. Patients usually lose a large volume of their excess fat after the sleeve gastrectomy procedure alone, but if weight loss ceases the second step of bypass is conducted in some patients.

For patients which are obese but not extremely obese, sleeve gastrectomy alone is a suitable operation with minimum risks. The sleeve gastrectomy currently is acceptable weight loss surgery option for obese patients as a single procedure. Most surgeons prefer to make use of a bougie between 32 - 60 Fr using the procedure and also the ideal approximate remaining size of the stomach after the procedure is about 15 mL.

How the sleeve gastrectomy procedure is done?

The majority of weight loss sleeve gastrectomies performed today use a laparoscopic technique, which is considered minimally invasive. Laparoscopic surgery usually produces a shorter stay in hospital, faster recovery, smaller scars, and fewer pain than open surgical treatments.

The amount of time from the surgery varies. One study found that the average operative time was 1.5 to three hours and also the average hospital stay was 2 to 5 days. Patients usually go back to normal activities in 2 weeks and are fully recovered in 30 days.

Laparoscopic sleeve gastrectomy could possibly be the initial step before gastric bypass or it's really a single process of weight loss. If a sleeve gastrectomy can be used included in a two-step procedure, the initial step is for the surgeon to produce the small stomach "sleeve." Over time of time based on choices, another procedure would be completed in which the surgeon attaches a piece of the small intestine directly to the stomach pouch. This enables food to bypass some of the small intestine. Doing so enables your body to soak up fewer calories, in addition to consuming less food. This two-step procedure may be done because patients may not be able to tolerate both procedures throughout a single operation. Studies show that the two-step procedure has been utilized successfully in patients having a bmi greater than 50 or perhaps in high-risk patients.
