Laparoscopic Gastric Bypass
Laparoscopic Roux-en-Y gastric bypass surgery is a procedure, which effectively reduces the size of the stomach in the patient. Approximately half of weight loss surgeries are gastric bypass surgery, making it the most popular form of bariatric surgery. The procedure has been the most effective in ensuring long-term weight loss. Gastric bypass surgery is an inpatient procedure, which requires a 24-hour hospital stay. The procedure involves dividing the stomach into two chambers, separating the chambers with surgical staples. The smaller portion of the stomach is then attached directly to a portion of the small intestine, bypassing the larger chamber created by the procedure. This effectively makes the stomach smaller, limiting the amount of food the stomach can hold and thereby lessening the amount of food you can eat. The procedure can be performed laparoscopically through small incisions. The smaller incisions cause less pain following surgery, fewer complications during recuperation, and shorter recovery times than open procedures.
Laparoscopic Sleeve Gastrectomy
Laparoscopic sleeve gastrectomy is a procedure which removes upwards of two-thirds of the stomach. This drastically reduces the amount of food you’re able to ingest. Patients feel fuller with much less food, making the restricted caloric intake easier. The portion of the stomach that is removed is responsible for Ghrelin production. Ghrelin is a hormone that is responsible for feelings of hunger, and so without Ghrelin, appetite is greatly reduced. The small portion of the stomach that is left creates resistance to food, making you feel full for a longer period of time. All of these effects of the laparoscopic sleeve gastrectomy dramatically reduce your appetite and how often you experiences physical feelings of hunger. In addition, the pylorus is not removed, so dumping syndrome is not as frequent. The bariatric surgery sleeve has a rate of 57%-81% of excess weight loss two to three years following the procedure.
