LAPAROSCOPIC SLEEVE GASTRECTOMY (Lap SG)
This is done as a solo restrictive operation or as a part of Lap BPD-DS mal-absorptive operation. It is also done as a stage 1 operation for super obese individuals to reduce their weight to the required level so that they can withstand more definitive Lap BPD-DS operation in future and surgical complications will also be less at that time. This became the most accepted and most popular solo restrictive operation in recent times. Using linear staplers 2/3 rd of the stomach is removed. Remaining stomach capacity is 60 to 120 ml if it is done as a solo restrictive operation or 150 to 200 ml if it is done as a part of mal-absorptive operation.
Fundus of stomach contains cells producing Ghrelin hormone which increases appetite. As fundus is removed during this surgery, appetite reduces after this operation. As stomach size is reduced, food intake is restricted. Because of loss of appetite and food restriction this operation gives reliable loss of weight. Weight loss is better after Lap SG compared to LAGB.

Laparoscopic sleeve gastrectomy is very safe if it is performed on the right candidate properly. But problems do occur in a small percentage of patients. They are related either to the anesthesia, surgery or postoperative management. After this operation problems like leak from the cut edges, narrowing of the stomach, vomiting can occur. Ineffective weight loss, inability to sustain weight loss and operation failure are problems associated with restrictive operations in certain percentage of patients. Ineffective weight loss, inability to sustain weight loss and operation failure are problems associated with restrictive operations in certain percentage of patients. Compared to restrictive + mal-absorptive operations and mostly mal-absorptive operations vitamin and mineral deficiencies are less likely after Lap SG. But these deficiencies can still occur due to reduced food intake. So, lifelong supplements are prescribed even after Lap SG.
