PS01.047: PROPHYLACTIC ANTI-REFLUX SURGERY AFTER LAPAROSCOPIC GASTRIC WEDGE RESECTIONS FOR GASTRIC SUBMUCOSAL TUMORS OF GASTROESOPHAGEAL JUNCTION

Abstract

Abstract Background A laparoscopic wedge resection (LWR) for a gastric submucosal tumor (SMT) close to gastroesophageal junction (GEJ) is technically challenging due to increased risk of damage to the lower esophageal sphincter. We hypothesized that GERD would be less prevalent if a prophylactic anti-reflux surgery (ARS) was added after this surgery. The aim of this study is to analyze our experience of prophylactic ARS after LWR for a gastric SMT close to GEJ Methods We retrospectively collected data from 51 patients who diagnosed with SMT of near the GEJ and who underwent LWR between January 2000 and December 2017. The patients were divided into 2 groups, the patient with prophylactic ARS (group A) or not (group B). Results There was no difference in the frequency of the preoperative GERD symptoms between the 2 groups, whereas postoperative GERD symptoms and postoperative use of acid suppressive medications were more frequent in the group B (P = 0.032, P = 0.036). However, there were no differences in the follow-up endoscopic findings in terms of reflux esophagitis and Hill's grade between the 2 groups. Conclusion The prophylactic ARS after LWR for SMT close to GEJ is an effective method of prevent gastroesophageal reflux symptoms after surgery.
