Laparoscopic Gastric Bypass

Laparoscopic Gastric Bypass

How it works:

The RNY gastric bypass surgery is a bariatric (weight loss) procedure that has been performed for about 30 years.  Most doctors and insurance companies have accepted it as the standard of care in the treatment of morbid obesity when diets and exercise fail. The traditional Roux-en-Y-gastric bypass was performed through open surgery with one long incision, but with the advancement of surgical instrumentation and stapling techniques most RNY are performed laparoscopically.  At the Chicago Institute of Minimally Invasive surgery we offer this procedure exclusively laparoscopically unless there are extenuating circumstances that would require an open procedure.  This is both a restrictive and malabsorptive procedure.  (See figure).  In this technique, the stomach is made smaller by creating a small pouch at the top of the stomach using surgical staples.  The smaller stomach is connected directly to the middle portion of the small intestine (jejunum), bypassing the rest of the stomach and the upper portion of the small intestine (duodenum).  Patients will feel full more quickly than when their stomach was its original size, which reduces the amount of food eaten and thus the calories consumed. Bypassing part of the intestine also results in fewer calories being absorbed.  Most bariatric surgeons divide a nerve called the Vagus when stapling the stomach in creating the new stomach pouch.  The Vagus nerve helps to regulate the digestive systems’ response to sweets and carbohydrates.  The Dumping Syndrome, which can cause nausea, diarrhea, and weakness, occurs when sweets enter the bloodstream too quickly.  Bariatric surgery that does not preserve the Vagus can cause the dumping syndrome and thus compromise the quality of life.

Dr. Frantzides was the first surgeon to define and publish the importance of preserving this nerve; and has been the founder of advanced surgical stapling techniques (Frantzides – Madan triple stapling technique) that have resulted in an extremely low rate of complications and high rate of patient satisfaction.  A list of some of Dr. Frantzides publications can be found by following this link:

What to expect after surgery:

Patient will be admitted to the telemetry floor of the hospital and can expect to be up and walking about two hours after surgery. The next day small sips of liquids will be allowed and if there is no discomfort or nausea the patient can expect to go home later that same day. Dr Frantzides asks that each patient returns to the office one week after surgery and then further advancement of diet (soft food) will be decided upon. Usually after three months there are no dietary or exercise restrictions. Dr. Frantzides wishes for long-term successful weight loss and health for all his patients and asks that each individual follows up diligently to ensure a good outcome and patient satisfaction.

Long-term outcome:

Patients should expect rapid weight loss in the first 6 months, which usually settles at a final weight at about 18-24 months after surgery.  One usually achieves about 70% to 80% excess body weight lost at 1 year. Motivated and complainant patients can achieve ideal body weight.
