In this procedure, the stomach is reduced to about 15% of it’s original size.
The surgeon keeps a vertical tube like portion of the stomach and removes the rest of it. The tube resembles a shirt sleeve. Hence, this procedure is called Sleeve Gastrectomy (SG). The retained portion of the stomach remains connected to the esophagus (food pipe) at the top and duodenum (small intestine) at the bottom.
By removing a large pouch-like part of the stomach, the surgeon effects moderate level of changes in the digestive tract. The change caused by Sleeve Gastrectomy are good enough to lose about 30kg to 40kg of excess body weight.
Sleeve Gastrectomy can help in reversing diabetes, but only if the disease is still in its early stages:
- If the disease has just set-in and the patient is not required to take any medication, the expected success rate is around 81%
- If the disease has advanced only moderately, and the patient is in oral medication, the expected success rate is around 59%
- If the diabetes is in its advanced stage, then the success rate of diabetes reversal can be as poor as 10%

Sleeve Gastrectomy also has one more limitation: This surgery is irreversible.
However, there is a single aspect wherein Sleeve Gastrectomy scores over bypass surgeries like Roux-en-Y, or Mini Gastric Bypass: SG is not a malabsorptive surgery. Meaning, people who undergo this surgery don’t have to be worried about vitamin/mineral deficiency.
Sleeve Gastrectomy is a rather uncomplicated surgery, requiring less of surgical skills. Hence, this is the most commonly offered procedure all over the world.
1 to 4 tiny incisions (1 for scarless surgery; 4 for regular laparoscopic surgery) are made in abdomen through which the surgeon accesses the stomach
Energy devices are used to demobilize the stomach and make it free to manipulate
The stomach is cut into two longitudinal pieces using a device called laparoscopic stapler. The stapler device is designed to simultaneously cut the stomach and stitch the remaining potion simultaneously.
The left-hand piece of the stomach, still attached to the esophagus and the duodenum, resembles a shirt sleeve. Whereas, the right side of the stomach, which is the remain portion of the stomach pouch, is removed.
The surgical team checks to ensure that the stitching of the remaining stomach has been done properly and retracts.
The patient is typically requested to remain in the hospital for 2 to 3 days after the surgery. After whih time, they are discchared from the hospital, with a request to take 5 more days of bed rest at home

All patients who undertake bariatric surgery at LIMA have five years of free support in terms of free consultation, patient education, bariatric community, life change coaching, etc.
The surgery results in reducing the size of the stomach, and hence the amount of food eaten. The surgery also results in some alteration of the digestive hormones. As a combined result, the paitent has a reduced appetite.
Because the patient is now eating smaller portions, and also because of the changes in the digestive hormones, the patient loses up to 30kg to 40kg of excess body weight. Some diabetes reversal might also occur if the patient is suffering from early/mild stage diabetes.
