Gastric Bypass
The “Gold Standard” procedure for metabolic and bariatric surgery, gastric bypass has both a restrictive and malabsorptive components that affect weightloss . A small pouch of stomach is created, separating the large stomach reservoir and upper small intestine from the esophagus. The small intestine is rerouted to the gastric pouch, diverting food directly into the small intestine and bypassing the stomach. The non-functional stomach and upper small intestine is reconnected back to the lower small intestine to empty digestive enzymes from the liver and pancreas back into the intestines. Gastric bypass offers on average 65-75% excess body weight loss, and often can improve diabetes and acid reflux
Sleeve Gastrectomy
Currently the most common procedure for weightloss being performed in the United States, a sleeve gastrectomy is a restrictive procedure that involves removal of approximately 80% of the stomach, turning the stomach from a large expandable reservoir into a narrow tube. This leads to patients feeling full quickly, and eating small portions. Sleeve gastrectomy is also associated with hormone changes that decrease hunger drive. On average, sleeve gastrectomy patients lose 45-50% of excess body weight.
Duodenal Switch/ SADI-S
These procedures are gaining popularity in metabolic and bariatric surgery. Duodenal switch and SADI-S offer the greatest excess body weight loss, often 70-90%, and are the most effective treatment for improving diabetes. Both procedures begin with a sleeve gastrectomy to create a smaller stomach. The small bowel just beyond the stomach, called the duodenum, is divided and the lower small bowel is reconnected to create a shortened small bowel for absorption of nutrients.
Revisional Surgery
Revisional bariatric surgery can be considered for a variety of reasons. These procedures vary based on previous surgery performed and patient needs. Common revisions include removal of gastric band with conversion to gastric bypass for treatment of acid reflux or difficulty swallowing, and conversion of sleeve gastrectomy to gastric bypass or SADI-DS for acid reflux or inadequate weight loss. Indications for revision of gastric bypass vary based on patient needs. Revisional procedures are often complex and require advanced planning. If you are considering revisional surgery, an in person consultation is recommended to discuss the specifics of your case.
Excess Skin Removal
Excess skin on the abdomen is common after weight loss from bariatric surgery. Dr Helak performs panniculectomy and radical abdominoplasty for patients with excess abdominal skin. We can also make referrals to plastic surgery based on patient needs.
