Bariatric Surgical Procedures
Gastric Bypass
The Roux-En-Y gastric bypass is a procedure in which a small gastric pouch is created from a portion of the upper stomach and then is directly connected to the small intestine. This restricts the amount of food that can be processed and reduces the absorption of that food. It also changes how the body releases hormones related to hunger and metabolism. All of this combines to help patients lose approximately 70 to 80 percent of their excess body weight. This is a well-studied and safe procedure that has been perfected over several decades. This surgery is now performed laparoscopically or robotically through small incisions, which allows for a quick recovery time with patients returning home within two days of the operation.
Gastric Sleeve
The sleeve gastrectomy is a procedure in which a thin stomach tube is created by stapling along a special sizing device and removing approximately 75 percent of the stomach. This provides the patient with a small residual stomach that holds much less food. Removing a significant portion of the stomach also removes many of the cells that produce one of the body’s major hunger hormones. These combined effects can help patients lose about 60 to 70 percent of their excess body weight. This surgery is performed laparoscopically or robotically through small incisions, which allows for a quick recovery time with patients returning home within two days of the operation.
Revision Surgery
Patients who have had bariatric surgery in the past occasionally need revision surgery. The two most commonly performed revision surgeries at our institution are adjustable gastric band removal and conversion of sleeve gastrectomy to Roux-En-Y gastric bypass. Our highly skilled surgeons are happy to offer these and other advanced services to patients regardless of where they had their original surgery. These surgeries are also performed laparoscopically or robotically with a quick recovery time.Are You a Candidate for Bariatric Weight-Loss Surgery?
