Featured Procedures

Gastric Bypass

Gastric bypass surgery is a bariatric procedure in which the stomach is divided into two separate pouches: an upper pouch and a lower pouch. The small intestine is then connected to the upper pouch. Gastric bypass contributes to better appetite control, healthy weight loss over time, and an improvement in various obesity-related health conditions.

Learn More about Gastric Bypass

Gastric Sleeve

Gastric sleeve surgery, also known as sleeve gastrectomy, is a bariatric procedure that involves removing about 75-80 percent of the stomach. This removal results in a new stomach pouch that is about the size and shape of a small banana. Gastric sleeve surgery results in effective appetite suppression and can improve many health conditions associated with obesity.

Also known as gastric banding, LAP-BAND is a medical device that restricts the stomach, making it smaller. Treatment with the LAP-BAND has the major advantage of being adjustable over time, allowing for steady and healthy weight loss. This bariatric surgery requires a shorter hospital stay and recovery period than other weight loss procedures. LAP-BAND is also reversible.

Revision Weight Loss Surgery

If you've undergone weight loss surgery but are dissatisfied with the results or have experienced complications, Dr. St. Laurent can perform a revision of your prior bariatric procedure. Revision surgery may also be appropriate for patients who experienced weight loss after an initial bariatric procedure, but the rate of weight loss has decreased or they have regained weight over time.

Laparoscopic Surgery ​Reduced Scarring and Recovery Time

Dr. St. Laurent performs all of his weight loss surgeries laparoscopically. During laparoscopic surgery, as opposed to traditional open surgery, the surgeon makes a few small incisions on the abdomen through which he inserts a laparoscope (a surgical camera) and small, extremely articulate surgical tools. The view provided by the camera allows Dr. St. Laurent to perform the surgery with minimal incisions and alteration of tissue.

Performing bariatric procedures like gastric bypass, gastric sleeve, bariatric revisions, and LAP-BAND placement utilizing laparoscopic techniques has many benefits. Laparoscopic surgery reduces the chances of surgical complications, produces less noticeable scarring, and decreases the time needed to recover from weight loss surgery.
