Is Gastric Bypass Surgery Worth the Risk?
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.
Stories about gastric bypass surgery, or "stomach
stapling," have made this procedure sound like a miracle. But it's not the
quick-and-easy fix that it might seem to be at first glance.
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
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
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.
The complications included a leak in the juncture attaching the
intestine to the stomach, which occurred in eight patients, and a disruption of
the staple line compartmentalizing the stomach, occurring in five patients.
Other complications of gastric bypass surgery included a blood clot in the
lung, blood infection, bleeding, pneumonia, bowel obstruction, and injury to
the esophagus. Merkle notes that these complications are more commonly seen
among severely obese patients having any type of surgery.
These findings should not discourage people from considering
gastric bypass surgery, but they should help them understand the serious nature
of the surgery, according to James A. Madura II, MD.
