Bariatric Surgery: Surgical Procedures
Most Procedures are done using minimally invasive (laparoscopic) surgery, which can help decrease hospital stay time and speed up your recovery.
This procedure, also called a Roux-en-Y gastric bypass, is one of the most commonly performed procedures for obesity in the United States. First, a small stomach pouch is created by stapling part of the stomach together or by vertical banding. This limits how much you can eat. Next, a Y-shaped section of the small intestine is attached to the pouch to allow food to bypass the duodenum as well as the first portion of the jejunum. This causes reduced calorie and nutrient absorption.
Laparoscopic Gastric Banding
This is a safe and effective way to achieve and maintain a healthier weight—without cutting or stapling your stomach. The procedure involves placing an inflatable band around the upper portion of the stomach to restrict the amount of food you can consume. This minimally invasive procedure is adjustable and reversible.
Sleeve gastrectomy involves surgically removing the left side of the stomach,
leaving a much smaller stomach about the size and shape of a banana. The stomach that remains is larger than a gastric bypass pouch, but much smaller than the normal human adult stomach. This causes restriction and a possible decrease in appetite due to gut hormones released by the removed fundus. The pylorus is preserved, so most patients should not experience "dumping syndrome." The procedure has no malabsorption and in theory, less nutritional deficiancies, as there is no bypassed intestine.
