INTRODUCTION: GERD is a common complication after sleeve gastrectomy (SG). The purpose of this study is assess the relationship between pre-operative findings of endoscopic esophagitis and post-operative GERD in SG patients. The hypothesis of this study is that patients with pre-op esophagitis are more likely to have GERD post-op than patients with no esophagitis pre-op.
METHODS: A retrospective review of 103 SG patients who had pre-operative endoscopy and followed prospectively for at least one year was preformed. Patients were divided into two groups based on pre-op endoscopic findings: those with no findings of esophagitis (NE), and those with endoscopic esophagitis, including Barretts (EE). Patients were followed for at least one year, and assessed for usage of a proton pump inhibitor (PPI) usage. The two groups were compared using both student t-test and chi square test.
RESULTS: A total of 63 patients did not have any findings of esophagitis on pre-op endoscopy (NE group), and 38 patients had findings of endoscopic esophigitis (EE). There was no difference in pre-operative demographics and post-op weight loss at one year (Table I).
% PPI usage
|% weight loss at one year||27%||27%||0.84|
|% Hiatal hernia repair||4.7%||15.7%||0.1|
Follow-up ranged from one to 4 years post-op. The dependency on PPI usage and de novo reflux are shown in Table II.
|% PPI usage post-op||36.5%||36.7%||0.97|
|De novo GERD post-op||20.9%||23%||0.83|
CONCLUSIONS: GERD and PPI dependency are common after SG. Patients with pre-op endoscopic esophagitis do not have a higher rate of PPI dependency post-op compared to patients who had no signs of pre-op esophagitis.
