Gastric Sleeve Surgery

Gastric sleeve surgery (also called Vertical Sleeve Gastrectomy, VSG, gastric sleeve, or “Sleeve”) is a surgical weight-loss procedure in which the stomach is reduced to about 25% of its original size, through surgical removal of a large portion of the stomach. The open edges are surgically stapled together to form a sleeve or tube with a banana shape. The procedure, performed laparoscopically, permanently reduces the size of the stomach and is irreversible.

A sleeve gastrectomy will help you to lose weight by restricting the volume of food consumed (provided that you are eating solid-type foods). The sleeve gastrectomy may also alter gastric hormone secretion for approximately one year, which helps to reduce hunger. Unlike a gastric bypass, a sleeve gastrectomy will not cause dumping syndrome, as the pyloric valve of the stomach is preserved with a sleeve.

The weight loss with a sleeve is similar to that of gastric bypass — approximately 50-70% of excess weight lost during the first year post-op. Weight-loss generally levels off after approximately one to two years, and a weight re-gain of up to 20 pounds is common. Unfortunately, at this time, there are not enough long-term studies to demonstrate the weight loss durability of the gastric sleeve procedure.

Dr. Provost can perform a sleeve gastrectomy in approximately 45 minutes. Patients can expect to spend one night in the hospital and are back to work with no restrictions in two to four weeks. The dietary guidelines following the sleeve gastrectomy are similar to those of Lap Band or gastric bypass.

Life-long follow-up with Dr. Provost and his team will provide the best weight-loss results. We will require you to come in every three months for the first two years, every six months for the third year, and annually thereafter.

Short-term complications following a vertical sleeve gastrectomy are similar to those of the gastric bypass and can include pulmonary emboli, anastomotic leak, bleeding and wound infection. The nationally reported operative (<30 days post-op) mortality rate is about 0.5 percent. This means that approximately one out of every 200 patients who have sleeve gastrectomy may die within 30 days of their surgery.

Long-term complications can include stricture, GERD, ulcers (smokers and those who take anti-inflammatories can expect increased risk!), gallstones, staple line disruption, weight re-gain, and vitamin/ mineral deficiencies.

Nutritional complications are few, and can generally be avoided with mandatory life-long supplementation of a daily multivitamin with iron, calcium citrate twice daily with vitamin D, and occasionally, B12. We will check your vitamin levels every six months for the first two years and annually thereafter.
