Special ESD Cases Illustrations: China

A large LST-G approximately sized 4 × 3 cm was found in the rectum near the anus. We used magnifying endoscopy with narrow-band imaging to carefully observe this lesion. Under magnifying endoscopy, it showed with regular tubular pattern with regular vessels, which was classified as JENT 2A. Also, positive regular WOS was observed. Finally, we considered it colorectal tubular adenoma and it could be resected with ESD. ESD was performed from the anal direction to the proximal direction and it was successfully dissected. Final histopathology was tubular adenoma.
