Endoscopic submucosal dissection (ESD) is the widely prevailing treatment for colorectal neoplasm. However, it is still technically difficult especially for lesions with fibrosis. We report the safety and feasibility of a pocket creation method (PCM) using DualJKnife, which enables additional submucosal injection between ESD, for colorectal lesions. Between June 2013 and March 2017, 13 of 184 cases of colorectal lesions were treated using ESD with PCM. As a result, the mean procedure time was 47.8 minutes, and the mean resected specimen size was 34.1 mm. The en bloc and complete resection rates were both 100%. As complication, no perforation (0%) occurred, but postoperative bleeding occurred in 1 case (7.7%) . Two lesions had previous biopsies, and 1 lesion had a fibrosis in the submucosal layer. However, a submucosal pocket was created in all the cases without any difficulty. In conclusion, ESD using PCM is reliable and safe for colorectal lesions and has good affinity with DualJKnife.
