Tips for the endoscopic retrieval of a large rectal tumor after endoscopic submucosal dissection by a forefinger‐compression method

Abstract

In endoscopic submucosal dissection (ESD) of large colorectal lesions, the retrieval of specimens though the anal canal is sometimes challenging. We introduced a simple technique to solve this problem using a forefinger‐compression method (FCM). A superficial tumor 80 mm in size showed nearly circumferential infiltration in the rectum (Fig. 1A).
