Sleeve Gastrectomy

Procedure: Sleeve Gastrectomy

How a Sleeve Gastrectomy Works

Sleeve GastrectomyA sleeve gastrectomy, or vertical sleeve gastrectomy, is a restrictive surgical weight loss procedure that limits the amount of food you can eat and helps you feel full sooner. During this procedure, a thin vertical sleeve of stomach is created using a stapling device, and the rest of the stomach is removed. The sleeve is about the size of a banana. It allows for normal digestion and absorption. Food consumed passes through the digestive tract in the usual order, allowing it to be fully absorbed in the body.

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

The length of time of the surgery varies. One study found that the average operative time was 1.5 to 3.5 hours and the average hospital stay was 2 to 5 days.14 Patients usually return to normal activities in 2 weeks and are fully recovered in 3 weeks.24

Weight Loss Surgery Benefits

Sleeve gastrectomy can lead to significant weight loss and improved health. Some advantages to this surgery include:

  • It is performed laparoscopically (minimally invasive)
  • May be an option for carefully selected patients, including high-risk or super-super-obese patients1.
  • Mean excess weight loss at 1 year of 59%2
  • No implanted medical device

Sleeve gastrectomy patients have been shown to experience significant weight loss and improvements in their health. Patients have been shown to lose an average of 55%13 of their excess weight.

Improvements in health, quality of life, and, of course, significant weight loss are important bariatric surgery benefits. The information below provides greater detail about these benefits and will help you understand how sleeve gastrectomy can help you achieve and maintain a healthier weight.

Quality-of-life improvements

Clinical studies of laparoscopic bariatric surgery patients found that they felt better, spent more time doing recreational and physical activities, benefited from enhanced productivity and economic opportunities, and had more self-confidence than they did prior to surgery.9

As you can see, a sleeve gastrectomy procedure may have many benefits. However, it isn’t for everyone. Only you and your surgeon can decide if bariatric surgery is an appropriate treatment option for you. Please see the education resources and links the end of this section for additional information.
