Bariatric Procedures

Opting for weight-loss surgery is not an easy choice. New treatments and safer techniques are making surgical intervention an option for more people. While the goal of any bariatric procedure is ultimately to improve health through medically supervised weight loss, results will vary depending on the procedure and the individual.

Greenwich Hospital offers three types of weight-loss surgery. Each uses a whole-person approach that includes a team of medical professionals to assess the physical, emotional and psychological health of the patient prior to surgery.

All procedures are done by Greenwich Hospital’s internationally recognized bariatric surgeons who use minimally invasive techniques, resulting in less scarring and quicker recovery.

Choosing the most appropriate type of surgery is determined on an individual basis depending on a patient’s health and circumstances.

Gastric Sleeve Surgery (Sleeve Gastrectomy or Gastric Sleeve Resection)

During this laparoscopic procedure, about 85 percent of the stomach is removed so that it takes the shape of a tube, sleeve or small banana. The tube-shaped stomach that is left is sealed closed with surgical staples.

Gastric sleeve patients require long-term lifestyle dietary changes and vitamin/mineral supplementation. There are some unique diet restrictions for the first four to six months after this surgery. Patients are gradually coached toward a balanced diet that includes lean meats, fish, soft poached eggs, fruits, vegetables and whole grains. Gastric sleeve patients are cared for in Greenwich Hospital’s surgical inpatient units by specialized nurses for 2 nights. This is the most common bariatric procedure at Greenwich Hospital.

Roux-En-Y (Gastric Bypass)

During gastric bypass, a small stomach pouch is created by stapling an area that holds no more than 1 to 2 ounces of solid food or liquid. A Y-shaped section of the small intestine is then attached to the pouch to allow food to bypass the rest of the stomach and the first part of the intestines. The other end of the small intestine is reconnected to the intestinal tract.

With gastric bypass, the body can no longer tolerate many foods that are high in saturated fat, sugar or starch — the kinds often found in commercially processed food items. The key to successful aftercare is the commitment to a lifetime behavior modification and maintenance plan, which includes a structured food plan and exercise program, plus regular follow-up with medical, nutritional, exercise and support group resources. All bypass patients are cared for in Greenwich Hospital’s surgical inpatient units by specialized nurses for 2 nights. This is the second most common bariatric procedure at Greenwich Hospital, and is sometimes preferred by patients who have problems with reflux.

Duodenal Switch

In a duodenal switch, a larger portion of the stomach is left intact, and the small intestine is rerouted. This procedure is used on a case-by-case basis when other methods are not appropriate or when patients with certain medical conditions don’t respond well to a different type of procedure.


 

Successful bariatric surgery is not just about weight loss. It’s about overall health. By medical standards, success is measured by losing at least 50 percent of a person’s excess weight and keeping it off for at least five years. Greenwich Hospital’s bariatric surgery team has results that show 80-90 percent 5-year success using the gastric sleeve and bypass procedures. Success is also dependent on a person’s commitment to a healthy lifestyle as well as changes in eating habits and physical activity.
