A woman in her seventies, who was experiencing bloody anal discharge, came to our hospital. Lower endoscopy showed a 30 mm 0-I lesion in the lower rectum. The tumor progressed to the anal side beyond the anal canal edge. In view of the observed bleeding from the venous plexus, the patient underwent combination surgery, consisting of endoscopic submucosal dissection (ESD) and transanal resection (TAR). Afterwards, there was little bleeding, and the horizon and vertical margins were negative.
Based on the success of combination surgery to treat this lower rectal tumor, which had progressed to the anal side beyond the anal canal edge, we predict that the combination of ESD and TAR may enable tumors to be resected more safely and completely.
