Bariatric surgeries are performed with the da Vinci surgical robotic platform, which allows for more precision. The surgeon can see better and have access to advanced instruments. This results in fewer complications during surgery and earlier discharge from the hospital.
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.
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.
Biliopancreatic Diversion with Duodenal Switch (BPD/DS)
This operation combines a gastric sleeve with shortening the length of the small intestine available to absorb the food you eat. This is a more aggressive approach resulting in more weight loss and less recurrence of obesity. This operation includes higher surgical risks and increased supplementation to prevent nutrient deficiencies.
