A recurrent lesion with severe fibrosis of colorectal endoscopic submucosal dissection using the combination of pocket-creation method and traction device

摘要

Colorectal endoscopic submucosal dissection (ESD) us- ing a pocket-creation method (PCM) is a technique that stabilizes the endoscope by creating a submucosal pocket below the tumor. 1 Our previous report showed that it was useful for resecting large colorectal tumors and lesions with severe fibrosis. 2 It is also useful in treating tumors when maneuverability of the endoscope is poor because of breathing movement and difficult location. However, it is sometimes difficult to create a submucosal pocket in PCM due to severe fibrosis and location.
