Video Summary

In this video, Dr. Mayu Tanabe from Showa University Koto Teosho Hospital presents a case of chronic ESD with SMD invasion. Due to the patient's age and comorbidities, ESD was performed. During the procedure, the muscle layer retraction sign made it difficult to identify the incision line, but it was resolved by identifying the submucosal layer on both sides of the retraction. Unexpected bleeding occurred, but was successfully treated using a coragrasper. A small perforation was closed using clips, and a PT1B lesion was resected with negative margins and no lymphovascular invasion. An additional stigmoidectomy was performed and no lymph node metastasis was found. The speakers also discussed techniques for managing muscle traction and fibrosis during ESD.
