Underwater endoscopic mucosal resection can achieve a submucosal cutting depth similar to that of conventional EMR for intermediate-sized colorectal lesions, a recent study from Japan has shown.
Comparing the cutting plane depth of nearly 170 colorectal polyp specimens obtained by either technique, investigators determined that underwater EMR “can be a viable alternative method that adequately resects the submucosal layer for the histopathological assessment of unpredictable submucosal
