The Durability of Endoscopic Therapy for Treatment of Barrett’s Metaplasia, Dysplasia, and Mucosal Cancer After Nissen Fundoplication

Introduction Radiofrequency ablation (RFA) ± endoscopic resection (EMR) is an established treatment strategy for neoplastic Barrett’s and intramucosal cancer. Most patients are managed with proton pump inhibitors. The incidence of recurrent Barrett’s metaplasia, dysplasia, or cancer after complete eradication is up to 43 % using this strategy. We hypothesize the addition of fundoplication should result in a lower recurrence rates after complete eradication. Methods Multi-institutional retrospective review of patients undergoing endotherapy followed by Nissen fundoplication Results A total of 49 patients underwent RFA ± EMR followed by Nissen fundoplication. Complete remission of intestinal metaplasia (CR-IM) was achieved in 26 (53 %) patients, complete remission of dysplasia (CR-D) in 16 (33 %) patients, and 7 (14 %) had persistent neoplastic Barrett’s. After fundoplication, 18/26 (70 %) remained in CR-IM. An additional 10/16 CR-D achieved CR-IM and 4/7 with persistent dysplasia achieved CR-IM. One patient progressed to LGD while no patient developed HGD or cancer. Conclusion Endoscopic therapy for Barrett’s dysplasia and/or intramucosal cancer followed by fundoplication results in similar durability of CR-IM to patients being managed with PPIs alone after endoscopic therapy. However, fundoplication may be superior in preventing further progression of disease and the development of cancer. Fundoplication is an important strategy to achieve and maintain CR-IM, and facilitate eradication of persistent dysplasia.
