Weight-Loss Surgery Has Its Problems but Can Be Lifesaving for Obese People
Dec. 2, 2003 (Chicago) -- Gastric bypass surgery can be lifesaving -- for the right person. A new study shows that many people will experience complications after surgery, but researchers say that it's worth the risk as a last option.
Gastric bypass surgery is great for motivated patients who are committed to permanent lifestyle change, according to lead researcher Elmar Merkle, MD. He presented his findings in Chicago at the annual meeting of the Radiological Society of North America.
"This should not be considered a cosmetic procedure," says Merkle in a news release. "People need to be aware of the potential complications of this surgery. It basically should be the last option we can offer the morbidly obese, after other less invasive interventions such as diet and exercise have been tried."
The procedure, known as gastric bypass surgery, attaches a piece of the small intestine higher up on the stomach and compartmentalizes the rest, so only a small portion of the stomach, approximately the size of an egg, is available for holding and digesting food. Therefore, patients feel full sooner.
And recently, gastric bypass surgery is being performed as a laparoscopic procedure, or through several small incisions, rather than one large incision. According to the National Institutes of Health guidelines, patients that are 100 pounds overweight can be considered for the surgery. Patients less than 100 pounds overweight may be considered if there is a life-threatening risk associated with their obesity, such as type 2 diabetes.
Merkle, associate professor of radiology at Duke University Medical Center in Durham, N.C., worked with a team of investigators when he practiced at University Hospitals of Cleveland. They followed 335 patients who underwent a type of gastric bypass surgery known as Roux-en-Y between March 1998 and December 2002.
Among these patients, 57 had complications and 17 required readmission to the hospital within 30 days after surgery. Two patients, or less than 1%, died as a result of postoperative complications.
