4_Endoscopic Submucosal Dissection of Colorectal Neoplasias Step-by-Step Explanation Technical Aspects

Video Transcription

Video Summary

The video describes the case of a 40mm 0-2C laterally spreading tumor non-granular type lesion in the ascending colon. Various imaging techniques such as indigocarmine dye spraying, narrowband imaging (NBI) with magnification, and crystal violet staining were used to determine that the lesion was an intramucosal cancer and a good candidate for endoscopic submucosal dissection (ESD) treatment. The ESD procedure was performed using an initial incision with a ball-tip B-knife, followed by submucosal dissection and completion using an IT knife. The procedure was successful with curative resection achieved.
