IDDF2021-ABS-0125 Evidence of objective endoscopic gastro esophageal reflux post sleeve gastrectomy

Abstract

<h3>Background</h3> Sleeve Gastrectomy (SG) is a popular bariatric surgery but its link to gastroesophageal reflux (GERD) is a concern as it’s associated with Barrett’s esophagus (BE). However, the development of GERD following SG is far from clear. Hence, the aim of this study was to look objectively for endoscopic esophagitis (EE) post SG. <h3>Methods</h3> The hospital record of all patients who had post SG endoscopy were reviewed retrospectively. Demographics, comorbidities, medications used, endoscopic findings and helicobacter pylori status were recorded <h3>Results</h3> 155 of the 169 patients who had a gastroscopy post SG were included, 14 were excluded, as there were done immediately post SG. Median age of patients was 35 years (range 18-65) with 59% (92) females and 48% (74) had hypertension, diabetes mellitus and/or hyperlipidemia. The median post SG endoscopy interval was 16 months (range 7–33). EE was detected in 23% (36) with 64%, 31% and 5% having grade A, B and C respectively. None had hiatus hernia and one of them had a 5cm Barrett’s esophagus (BE). In addition, 26 patients had endoscopy prior to SG of which 15% (4) had esophagitis post SG and none had esophagitis prior to SG. 19% (30) were positive for helicobacter pylori (HP) and 23% of these had esophagitis. Compared to those without HP, the prevalence of esophagitis was not significantly different (P = 1.00). <h3>Conclusions</h3> Endoscopic esophagitis was prevalent in nearly a quarter of our study population. The development of EE may be denovo with the potential to evolve into BE.
