BACKGROUND: Esophagectomy is the conventional treatment for Barrett's esophagus with high-grade dysplasia and intramucosal cancer. Endotherapy is an alternative treatment. OBJECTIVE: To compare the efficacy and safety of these 2 treatments. DESIGN: PubMed, Web of Science, EMBASE, Cochrane Library and momentous meeting abstracts were searched. Studies comparing endotherapy with esophagectomy were included in the meta-analysis. Pooling was conducted in a random-effects model. SETTING: Tertiary-care facility. PATIENTS: Seven studies involving 870 patients were included. INTERVENTION: Endotherapy and esophagectomy. MAIN OUTCOME MEASUREMENTS: Neoplasia remission rate, neoplasia recurrence rate, overall survival rate, neoplasia-related death, and major adverse events. RESULTS: Meta-analysis showed that there was no significant difference between endotherapy and esophagectomy in the neoplasia remission rate (relative risk [RR] 0.96; 95% CI, 0.91-1.01); overall survival rate at 1 year (RR 0.99; 95% CI, 0.94-1.03), 3 years (RR 1.03; 95% CI, 0.96-1.10), and 5 years (RR 1.00; 95% CI, 0.93-1.06); and neoplasia-related mortality (risk difference [RD] 0; 95% CI, -0.02 to 0.01). Endotherapy was associated with a higher neoplasia recurrence rate (RR 9.50; 95% CI, 3.26-27.75) and fewer major adverse events (RR 0.38; 95% CI, 0.20-0.73). LIMITATIONS: Relatively small number of retrospective studies available, different types of endoscopic treatments were used. CONCLUSION: Endotherapy and esophagectomy show similar efficacy except in the neoplasia recurrence rate, which is higher after endotherapy. Prospective, randomized, controlled trials are needed to confirm these results.
