To meet the needs of as many patients as possible in the Southern Maryland and Washington, D.C. region, MedStar St. Mary's offers several types of weight loss surgery in conjunction with MedStar Washington Hospital Center and MedStar Georgetown University Hospital. The majority of weight loss surgeries use a laparoscopic technique, which is considered minimally invasive. Laparoscopic surgery usually results in a shorter hospital stay, faster recovery, smaller scars, and less pain than open surgical procedures.

As with any abdominal surgery, potential risks exist; however, with bariatric surgery, these risks are further complicated because of the patient's extra weight. You should discuss the benefits and risks of each type of surgery in detail with your surgeon and our bariatric surgery team, to determine which one is right for you.

Our board-certified surgeon, Dr. Nicholas Tapazoglou, leads our multi-disciplinary bariatric team. A nurse program coordinator, dietician, and an exercise physiologist coordinate your care and guide you through the entire process of bariatric surgery. Extensive follow-up care provides the support you need well after whichever procedure you have.

Sleeve Gastrectomy

During a sleeve gastrectomy, a thin vertical sleeve of stomach is created using a stapling device, and the rest of the stomach is removed, reducing the stomach to approximately 15 percent of its original size. By reducing the size of the stomach, the amount of food that can be ingested is decreased.  Additionally, the hormone responsible for signaling hunger is contained in the portion of the stomach removed.

Gastric Bypass

Gastric bypass may be right for individuals whose excess weight and weight-related medical conditions threaten to shorten their lives. During gastric bypass surgery, the stomach is divided to make a smaller pouch. This smaller pouch is then attached to a portion of the intestine, bypassing the larger stomach and the first part of the smaller intestine. The surgery changes the absorption rate of food, as well as decreasing the amount that can be ingested.
