Gastric Banding vs. Gastric Bypass Surgery

If you’re considering undergoing bariatric surgery in order to reach and maintain a healthy weight, a gastric banding or gastric bypass procedure might be right for you. Gastric banding surgery is a minimally invasive procedure that uses patented technology to restrict the size of the stomach and limit food intake. During surgery, an inflatable silicone band is place around a portion of the stomach. In gastric bypass surgery, a small part of the stomach is sectioned off and the middle portion of the small intestine is attached to it; food then bypasses the upper part of the small intestine and the rest of the stomach. New Haven bariatric surgeon Elmer Valin performs gastric bypass and banding procedures on our Connecticut patients.

Successful Outcomes

Gastric bypass and banding procedures effectively reduce the size of the stomach and make patients feel full after eating small amounts of food. Patients that undergo gastric banding and bypass procedures can successfully lose a substantial amount of weight when they have the surgery and commit themselves to adopting a healthier lifestyle.

Permanent vs. Adjustable and Reversible Treatment

A number of patients prefer to undergo gastric banding procedures such as REALIZE™ Band and LAP-BAND® System Surgery because these procedures are adjustable and reversible. Gastric bypass surgery involves the resection of the stomach and small intestine, and it cannot be reversed. In general, bariatric surgeons do not recommend that gastric banding procedures be reversed because patients have a tendency to gain the weight back. However, if patients are unable to maintain a healthy lifestyle and follow post-bariatric surgery guidelines, the band may be removed.

Laparoscopic Technology

Both gastric bypass and gastric banding procedures can be performed using a laparoscope, or camera, that is inserted into the abdomen. During surgery, a series of small incisions are made on the abdomen. New Haven gastric bypass surgeon Elmer Valin inserts the scope, or camera, and small surgical tools, through thin tubes placed through the incisions. The use of laparoscopic technology results in a shorter surgical procedure, brief hospital stay, and a faster recovery.

Side Effects and Risks

With any surgical procedure, there are inherent risks that include bleeding, clots, and infection. There are also side effects and risks with gastric bypass and banding surgery. Some of these side effects can include:

• Bloating
• Heartburn
• Nausea
• Abdominal pain
• Food intolerance
• Dehydration
• Constipation

Side effects specific to gastric banding include dumping syndrome, a condition in which undigested food in the stomach pouch rapidly moves into the small intestine. The symptoms that result include the sweats, vomiting, stomach pain, diarrhea, fast heart beat,  and fatigue.

A risk that is specific to gastric banding procedures is the potential for the band to leak, slip, or twist, requiring an office adjustment or an additional laparoscopic procedure.
