The effect of bariatric surgery on gastroesophageal reflux disease.

Obesity is an epidemic that is known to play a role in the development of gastroesophageal reflux disease (GERD). Studies have shown that increasing body mass index plays a role in the incompetence of the gastroesophageal junction and that weight loss and lifestyle modifications reduce the symptoms of GERD. As a method of producing effective and sustainable weight loss, bariatric surgery plays a major role in the treatment of obesity. We reviewed the literature on the effects of different types of bariatric surgery on the symptomatic relief of GERD and its complications. Roux-en- Y gastric bypass was considered an effective method to alleviate symptoms of GERD, whereas laparoscopic sleeve gastrectomy appeared to increase the incidence of the disease. Adjustable gastric banding was seen to initially improve the symptoms of GERD; however, a subset of patients experienced a new onset of GERD symptoms during long-term follow-up. The literature suggests that different surgeries have different impacts on the symptomatology of GERD and that careful assessment may be needed before performing bariatric surgery in patients with GERD.
