7_How to Prevent Complications at ESD of Colorectal Lesions

Video Transcription

Video Summary

The video transcript describes a procedure for removing a laterally spreading tumor in the lower rectum. The tumor has a granular phenotype and measures 50 mm in diameter. The procedure involves injecting sodium hyaluronate to elevate the mucosal layer and then making a shallow mucosal incision to avoid damaging submucosal vessels. The small ramified vessels are dissected using force coagulation mode, and a large horizontal vessel is pre-coagulated and dissected. Attention is given to avoid cutting larger blood vessels to prevent vision loss and complications. The procedure includes additional dissection, forming a mucosal flap, preventing unintended vessel cutting, and completing the final dissection without major bleeding or injury. Histological assessment confirms a 48-mm intramucosal cancer without lymph vascular invasion and clear margins. No credits were mentioned in the transcript.
