Sleeve gastrectomy, also referred to as vertical sleeve, gastric sleeve or tube gastrectomy, is a surgical procedure performed for the treatment of obesity. The procedure is a restrictive bariatric surgery to treat extremely obese patients with a high BMI of 40 and above. It encourages weight loss by restricting the stomach size so it holds only a limited amount of food. This helps patients to eat less without hampering the normal digestive process.
Sometimes sleeve gastrectomy is carried out as a first stage of a 2-stage operation in extremely obese patients with a BMI of 60 or more. This is done to achieve a considerable amount of weight loss so it is safer for the patient to undergo a second bariatric surgery if needed.
Obesity is a chronic condition in which there is an excessive accumulation of fat in the body.
Obesity is defined as a Body Mass Index (BMI) of 30 to 34.9 and extreme or morbid obesity is a BMI of 40 or more.
Obesity is a global problem affecting people of almost all age groups, and is associated within creased risk of cardiac problems, diabetes, high blood pressure, breathing difficulties, and other diseases.
Sleeve gastrectomy is indicated for people with a BMI of 37(Asian population) and more, and also in those whose BMI is 30 and above and suffering from obesity associated conditions.
The surgery is recommended when diet, exercise or medication have not helped in reducing the patients weight.
The procedure is performed under general anaesthesia. The surgeon makes 2 to 5small incisions on your abdomen. A laparoscope, a thin instrument with a light and camera attached, is inserted through one incision, allowing your surgeon to clearly view the internal organs on a monitor.
Additional surgical instruments are inserted through the other incisions. Your surgeon will remove nearly 75-80% of the stomach. A thin sleeve shaped like a banana is created by stapling the remaining part of the stomach. At the end of the procedure, the incisions are closed with sutures.
Your doctor will prescribe pain relieving medications to keep you comfortable following the procedure.
As with any surgery there are potential risks and complications involved. The risks include blood loss, infections, problems associated with anaesthesia, and deep vein thrombosis (blood clot in the leg).
The major complication following sleeve gastrectomy surgery is occasional leakage or breakdown of the gastric contents from the staple line that secures the divided stomach.
