Laparoscopic sleeve gastrectomy (LSG) is a procedure to reduce the size of the stomach and thereby limit food intake. During the procedure, approximately 75-85 percent of the stomach is removed, leaving a narrow gastric sleeve or tube that limits the amount of food that can be eaten at one time. After eating a small amount, patients feel full and remain satiated for several hours.
In addition to reducing stomach size, LSG decreases the amount of “hunger hormone (Ghrelin)” produced by the stomach and, in turn, causes a decrease in appetite that is thought to be the main mechanism of weight loss. LSG takes about one hour to complete and requires no post-operative drain or nasal tube. Patients can typically return to work or resume strenuous activity approximately one week after surgery.
LSG uses four or five small abdominal incisions to provide access to a video camera and instruments. The stomach is restricted by stapling and divided to reduce its size. Although the volume is significantly reduced, the nerves to the stomach and the outlet valve remain intact. The intestines are not removed or bypassed, and the procedure does not cause decreased absorption of nutrients. Because there is no intestinal bypass, potential complications such as marginal ulcers, vitamin deficiencies, and intestinal obstructions are avoided.
Benefits and Risks of Laparoscopic Sleeve Gastrectomy
Benefits
- Patients may lose 30-35% of their total body weight (roughly 50-80%of their excess weight) in the first year after surgery.
- The laparoscopic technique typically results in small scars, reduced pain, and faster recovery.
- Obesity-related problems, such as hypertension, diabetes, sleep apnea, and abnormal cholesterol levels, are improved in patients who undergo LSG.
- Patients may return to work and strenuous activities one week after surgery.
- Stomach capacity is reduced, but the function remains unimpaired so that most foods can be eaten.
- Avoiding intestinal bypass virtually eliminates the chances of intestinal obstruction and ulcers, and, reduces the chances of osteoporosis, and protein and vitamin deficiencies although regular vitamin, mineral, iron, and protein supplementation is recommended.
Disadvantages:
- Although the procedure does not reduce your ability to absorb nutrients and calories; you must take iron, mineral, vitamin, and protein supplements for the rest of your life.
- Following surgery, you must follow the low-sugar and low-starch diet guidelines since you may experience discomfort, including vomiting and diarrhea.
- This procedure is not reversible.
- Complications include the possibility of leaks, bleeding, blood clots, infection, and blockages.
