Video Summary

In this video, Dr. Yutaka Saito performs an endoscopic submucosal dissection (ESD) of a large sigmoid colon polyp. The patient is a 40-year-old female with painless hematochezia. The lesion is a 40mm sigmoid polyp with a granular homogeneous LST (laterally spreading tumor) pattern. Biopsies revealed a tubular adenoma. Dr. Saito demonstrates the procedure using a pocket creation method, starting with a retroflex position and changing to a straightforward view due to difficulty in maneuvering the scope. He dissects the lesion using an IT knife nano as well as an All-Rise Pro knife. Throughout the procedure, Dr. Saito discusses various techniques and strategies, including the use of traction devices like dental floss and clip bands, diathermic settings, the use of Puristat to decrease the risk of delayed bleeding, and the potential benefits of using red dichromatic imaging (RDI) and gel immersion. The video ends with the completion of the dissection, the application of Puristat, and the plan to retrieve the tumor. This summary is based on the transcript provided.
