Laparoscopic sleeve gastrectomy can be the first step before gastric bypass or it can be a single procedure for weight loss. If a sleeve gastrectomy is used as part of a two-step procedure, the first step is for the surgeon to create the small stomach "sleeve." After a period of time determined by the surgeon, another procedure would be done in which the surgeon attaches a section of the small intestine directly to the stomach pouch. This allows food to bypass a portion of the small intestine. Doing so enables your body to absorb fewer calories, in addition to consuming less food. This two-step procedure may be done because patients may not be able to tolerate both procedures during a single operation. Studies show that the two-step procedure has been used successfully in patients with a body mass index greater than 50 or in high-risk patients.
During this procedure, a thin vertical sleeve of stomach is created using a stapling device, and the rest of the stomach is removed. The sleeve is about the size of a banana. This procedure limits the amount of food you can eat and helps you feel full sooner. It allows for normal digestion and absorption. Food consumed passes through the digestive tract in the usual order, allowing it to be fully absorbed in the body.
- Limits the amount of food that can be eaten at a meal.
- Food passes through the digestive tract in the usual order, allowing vitamins and nutrients to be fully absorbed into the body.
- No postoperative adjustments are required.
- In clinical studies patients lost an average of 55% of their excess weight.
- Shown to help resolve high blood pressure and obstructive sleep apnea, and to help improve type two diabetes and hyperlipidemia.
- Complications due to stomach stapling, including separation of tissue that was stapled or stitched together and leaks from staple lines.
- Gastric leakage.
- Dyspepsia (upset stomach or indigestion).
- Esophageal dysmotility (difficulty swallowing and regurgitation of food)
