Introduction The role of endoscopic submucosal dissection (ESD) in the treatment of Barrett’s associated neoplasia (BEN) has been evolving. We examined the efficacy and safety of ESD and EMR for BEN. Methods A database search was performed for studies reporting efficacy and safety outcomes of ESD and EMR for BEN. Pooled proportional and comparative meta-analyses were performed. Results 47 studies (23 ESD, 19 EMR, and 5 comparative) were included. Mean lesion size for ESD and EMR were 22.5 mm and 15.8 mm respectively. Majority of lesions were Paris type IIa. Pooled analysis for ESD showed en-bloc resection, R0 resection, curative resection, and local recurrence rates of 98%, 78%, 65%, and 2%, respectively. Complete eradication of dysplasia (CE-D) and complete eradication of intestinal metaplasia (CE-IM) were achieved in 94% and 59% of cases. Pooled rates of perforation, intraprocedural bleeding (IPB), delayed bleeding (DB), and stricture were 1%, 1%, 2%, and 10%, respectively. Pooled analysis for EMR showed en-bloc resection, R0 resection, curative resection, and local recurrence rates of 37%, 67%, 62%, and 6%, respectively. CE-D and CE-IM were achieved in 94% and 76% of cases. Pooled rates of perforation, IPB, DB, and stricture were 0.1%, 1%, 0.4%, and 7.7%, respectively. The mean procedure time for ESD and EMR were 111.3 and 22.3 mins respectively. Comparative analysis showed higher en-bloc and R0 resection rates with ESD compared to EMR, with comparable adverse events. Conclusion ESD and EMR both can be employed to treat BEN depending on the lesion type, size, and expertise.
