Sleeve gastrectomy
Principle of gastric sleeve surgery
The Gastric sleeve surgery is a type of weight loss surgery. Weight loss surgery is also called bariatric surgery. This operation is also known as sleeve gastrectomy or vertical sleeve gastrectomy. Sleeve Gastrectomy surgery limits your food intake, which leads to weight loss.
It is a laparoscopic surgery, with small incisions in the upper abdomen. Most of the left side of the stomach is removed. The remaining stomach is then a narrow tube called a sleeve. Food empties from the lower stomach into the small intestine the same way it did before surgery. The small intestine is neither operated nor modified. After surgery, less food will fill you up when you eat.
Who should undergo a sleeve gastrectomy
Gastric sleeve surgery is used to treat severe obesity. It is recommended for people who have tried other weight loss methods without long term success. Your doctor may advise gastric sleeve surgery if you are severely obese with a body mass index (BMI) over 40. Your doctor may also advise if you have a BMI between 35 and 40 and a problem with health such as sleep apnea, high blood pressure. , heart disease or type 2 diabetes.

He or she will make several small cuts (incisions) in the upper abdomen. The surgeon will then insert a laparoscope and put small surgical tools through these incisions.
The anesthesiologist will then pass a sizing tube through your mouth into your stomach. The surgeon will then use a laparoscopic stapler to divide the stomach, leaving a narrowed vertical sleeve. The part of the stomach that has been removed is then extracted from the abdomen through an incision. Your surgeon can then look for any leaks in the sleeve using dye or upper endoscopy.
