Efficacy and histologic accuracy of underwater versus conventional endoscopic mucosal resection for large (> 20 mm) colorectal polyps: a comparative review and …
Background and Aims Major limitations with conventional EMR (C-EMR) include high rates
of polyp recurrence and low en-bloc resection rates, especially for lesions> 20 mm in size.
Underwater EMR (U-EMR) has emerged as an alternate technique for en-bloc resection of
larger lesions. We conducted a systematic review and meta-analysis comparing the efficacy
and safety of the 2 techniques. Methods Multiple databases were searched through June
2020 for studies that compared outcomes of U-EMR and C-EMR for colorectal lesions. Meta …
