The Hill's Classification Is Useful to Predict the Development of Postoperative Gastroesophageal Reflux Disease and Erosive Esophagitis After Laparoscopic Sleeve Gastrectomy

Background: Laparoscopic sleeve gastrectomy (LSG) is one of the commonest bariatric procedures. However, it is associated with postoperative gastroesophageal reflux disease (GERD) and erosive esophagitis (EE). This study aims to assess the impact of various preoperative clinical and endoscopic characteristics on the development of postoperative GERD and EE. Methods: A single institution retrospective cohort study involving all patients who underwent LSG. A univariate and multivariate analysis was performed to identify preoperative parameters that were significantly associated with the development of postoperative GERD and EE, at up to 1-year follow-up. Results:At up to 1-year follow-up, out of 127 patients, only preoperative endoscopic presence of a hiatal hernia noted on axial length (p=0.024), and the Hill’s classification of the gastroesophageal junction (p
