NEW YORK (Reuters Health)-an older form of Lap-Band Surgery weight-loss can lead to serious complications over the long haul, Belgian researchers said Monday.
The operation works by placing a silicone band around the upper part of the stomach to limit the intake of food. It Is an increasingly popular option in the fight against obesity, but some experts have concerns about their safety.
The Belgian team found that as much as half of their patients followed for at least 12 years, the band removed during that period. And in more than a quarter, the band had gnawed its way through the wall of the stomach.
"The high failure rate of (Lap-Band Surgery), at least in our hands, its future may harm further widespread use as a restrictive weight loss surgery," write Dr. Jacques Himpens of the Saint Pierre University Hospital in Brussels and colleagues in the archives of surgery.
"This is what I was worried about," said Dr. Mary Brandt, which is at the head of the pediatric surgical program in Texas children's Hospital in Houston and the Lap-Band Surgery for criticised.
"I think these data to support my opinion that lap-band is not the correct operation for adolescents," she told Reuters Health in an e-mail.
According to Allergan-Irvine, California-based company that the Lap-Band system makes--is its product used in more than 500,000 procedures worldwide. The command more than two-thirds of a market of $ 300 to $ 400 million.
In an email to Reuters Health, Allergan criticism of the new study and said that both the surgical technique and the Lap-Band itself was changed in the meantime.
Also noted that the study was based on only 151 patients from a single hospital, and that the researchers were able to test only half of the patients.
"We are disappointed to see the publication of an ill-built, single-center clinical assessment that does not meet the high clinical standards a should expect from peer-reviewed data, and is not reflective of the clinical standards of today," Cathy TaylorAllergan, the Director of Corporate Communications, said.
Dr. Marc p. Michalsky, surgical Director of the Center for healthy weight and nutrition at nationwide children's Hospital in Columbus, Ohio, seconded the criticism.
"In some ways that it's a bit of a historical snapshot of this type of surgery 15 years ago," he said. "I would these results with a grain of salt."
On average, patients in the study lost about 43 percent of their excess weight--a number which was overtaken by the gold standard weight loss surgery, called gastric bypass.
Four of every ten patients in the study suffered a major complication of surgery, such as the band going into the stomach or the stomach pouch. Overall, six out of ten patients ended up on the operating table again.
In 2009 had more than 220,000 Americans a kind of weight loss surgery, at a price of about $ 20,000 per patient, according to the American Society for Metabolic and Bariatric Surgery.
"I don't think there is one operation that is good for everyone," said Michalsky. "It really comes down to a combination of recitals by the surgeon and the patient."
