    Abstract:
    BACKGROUND: Gastroesophageal reflux disease (GERD) is highly prevalent in morbidly obese patients and a high body mass index is a risk factor for the development of this co-morbidity. The effect of laparoscopic sleeve gastrectomy (LSG) on GERD is poorly known. METHODS: We studied the effect of LSG on GERD in patients with morbid obesity. A retrospective review of 28 consecutive patients undergoing LSG for morbid obesity from September 2008 to September 2010 was performed. RESULTS: A total of 28 patients, 18 women and 10 men, were identified, with a mean age of 42 years (range 18-60). The mean weight and body mass index was 166 kg and 55.5 kg/m2, respectively. The mean percentage of excess weight loss was 40% (range 17-83), with a mean follow-up time of 32 weeks (range 8-92). All patients had a pre- and postoperative upper gastrointestinal radiographic swallow study as a part of their routine care. Of these patients, 18% were noted to have new-onset GERD on their postoperative upper gastrointestinal swallow test after their LSG procedure. Using the GERD score questionnaire, all patients were interviewed to evaluate their reflux symptoms. We had a 64% response rate, with 22% of patients indicating new-onset GERD symptoms despite receiving daily antireflux therapy. All respondents were extremely happy with their surgery and weight loss to date. CONCLUSION: LSG might increase the prevalence of GERD despite satisfactory weight loss. Additional studies evaluating esophageal manometry and ambulatory 24-hours pH-metry are needed to better evaluate the effect of LSG on gastroesophageal reflux symptoms.
