The finding stems from a review of research on the link between = obesity and=20 reflux. The experts concluded that gastric bypass may help reduce GERD, = but=20 gastric banding does not -- a finding patients may want to consider when = choosing one form of weight-loss surgery over another.

"For people with obesity and reflux together, the gastric bypass = procedure=20 appears to be effective not only for weight loss, but also for the = control of=20 reflux symptoms," concluded the review's lead author, Dr. Frank K. = Friedenberg,=20 an associate professor in the section of gastroenterology at Temple = University=20 School of Medicine, Philadelphia. "Because in this case, most of the = acid from=20 the stomach is being partitioned away, so it doesn't have exposure to = the=20 esophagus," he explained.

"However, with gastric banding, the problem is that you actually = create a=20 pocket which acid has the ability to fill from the remainder portion of = the=20 stomach," Friedenberg said. "And this acid can just sit there above the = band,=20 and make its way back up to the esophagus. This can cause reflux disease = to=20 develop, or make it worse than it had been if it was a problem before = the=20 procedure."

Friedenberg and his colleagues published their findings in the August = issue=20 of The American Journal of Gastroenterology.

Gastroesophageal reflux disease (GERD) occurs when a muscle at the = end of the=20 esophagus does not close properly, allowing irritating stomach contents = to leak=20 back into the esophagus. Symptoms include heartburn and acid = indigestion.

According to the new analysis, involving numerous studies, a high = body mass=20 index (BMI) and/or high amounts of abdominal fat does appear to raise = the odds=20 for significant acid reflux.

The researchers also found that diet-induced weight loss can help = minimize=20 GERD symptoms.

However, not all weight-loss surgeries were equally beneficial with = respect=20 to GERD, Freidenberg's team found.

Across several studies, a procedure known as Roux-en-Y gastric bypass = --=20 which involves the creation of a small gastric pouch walled off from (or = bypassing) the rest of the stomach and intestinal track -- consistently = appeared=20 to help patients shed pounds and eliminate or reduce GERD = symptoms.

However, laparoscopic (gastric) banding was found to be less helpful = in=20 tackling GERD.

The popular surgery, which involves the placement of a band to divide = and=20 reduce the size of the stomach, initially debuted in 1993. It has proven = effective in helping patients feel satiated earlier, spurring weight = loss.

Patients often did lose weight after banding, the researchers found, = and this=20 reduction in weight did not immediately encourage GERD. In fact, in some = cases,=20 post-procedure weight loss appeared to moderately reduce some reflux = disease=20 symptoms, the researchers said.

However, the inserted gastric band often seems to shift in place over = time,=20 they said, leading to a reversal of any initial benefit and a gradual = worsening=20 of GERD symptoms.

Based on these findings, Friedenberg and his team concluded that = gastric=20 bypass may be "the preferred surgical technique" with specific regard to = GERD=20 risk. But they also pointed out that more rigorous studies need to be = conducted=20 to better understand the how's and why's of reflux disease in the = context of=20 weight-loss surgery.

One expert said the current work highlights the need to carefully = assess the=20 pros and cons of each weight-loss procedure.

"Gastric bypass is the most common and the most successful of the = surgical=20 procedures to deal with obesity," noted Dr. Anthony A. Starpoli, an = attending=20 gastroenterologist at Lenox Hill Hospital and director of = gastro-esophageal=20 research and endo-surgery at St. Vincent's Hospital, both in New York = City. "But=20 the advantage to the banding procedure is that, although it will not be = an=20 effective option for all patients -- depending on the level of obesity = -- it's a=20 lot less aggressive than bypass and has a lot less morbidity associated = with it.=20 And it's much more reversible. So, there are reasons some patients might = choose=20 that option."
