Laparoscopic sleeve gastrectomy, a weight-loss surgery that removes much of the stomach and forms the remainder into a tube, does not resolve or relieve patients' acid reflux conditions as reliably as gastric bypass surgery does, say researchers.
For their study, published online by JAMA Surgery on Feb. 5, a team of researchers from the Madigan Army Medical Center in Tacoma, Wash., reviewed a national database of bariatric surgery outcomes. The database followed up on patients who'd undergone weight-loss procedures from 2007 to 2010.
They found that out of 4,832 laparoscopic sleeve gastrectomy patients, 84.1% of those who'd reported gastroesophageal reflux disease before the surgery continued to suffer the symptoms afterward and 8.6% developed GERD symptoms post-operatively.
However, 62.8% of the GERD sufferers among the 33,867 gastric bypass surgery patients reported a complete resolution of their symptoms, with 17.6% seeing their symptoms stabilize and only 2.2% seeing them worsen. The gastrectomy GERD patients also saw reduced outcomes in terms of weight loss.
