The USC Bariatric Surgery Program offers different surgeries:
This is the latest restrictive weight loss procedure that reduces food intake due to the reduction of stomach size. The surgeon creates a small, sleeve-shaped stomach in the shape of a banana. The stomach pouch that is created is larger, yet narrower than the one created in the Laproscopic Roux-en-Y Gastric Bypass. But, similarly, the sleeve reduces the secretion of the hunger hormone ghrelin. The sleeve gastrectomy can also be considered as an option for obese patients with a large abdominal hernia because it also helps with hernia treatment.
Roux-en-Y gastric bypass surgery uses a combination of restriction and malabsorption. During the procedure, the surgeon creates a smaller stomach pouch. The surgeon then attaches a Y-shaped section of the small intestine directly to the pouch. This allows food to bypass a large portion of the small intestine, which absorbs calories and nutrients. Having the smaller stomach pouch causes patients to feel fuller sooner and eat less food; bypassing a portion of the small intestine means the patient’s body absorbs fewer calories.
A revision of weight-loss surgery is done on a patient who underwent weight loss surgery, including lap band, duodenal switch, sleeve and gastric bypass, and may be experiencing a variety of symptoms or complications after the operation. Some of the symptoms go away with simple medical measures, but others will persist and become even worse over time. These symptoms can include vomiting, heartburn, chest pain, regurgitation of food, constant abdominal pain, stomach and intestinal ulcers and other gastrointestinal symptoms. Other symptoms can include excessive weight loss and inability to maintain a stable and reasonable weight, poor or no weight loss, and even weight regain. Vitamin and protein deficiency could be another cause for concern and need for revision.
