Local excision under direct vision is technically possible only in the distal rectum. Higher lesions could be treated with transanal endoscopic microsurgery which required the availability of an expensive dedicated system. Transanal minimally invasive surgery is a significant innovation as it can be carried out using a laparoscopy system and few widely available specific instruments. This allows local excision for higher rectal lesions which would otherwise require either anterior resection or suboptimal endoscopic procedures.

摘要

Local excision under direct vision is technically possible only in the distal rectum. Higher lesions could be treated with transanal endoscopic microsurgery which required the availability of an expensive dedicated system. Transanal minimally invasive surgery is a significant innovation as it can be carried out using a laparoscopy system and few widely available specific instruments. This allows local excision for higher rectal lesions which would otherwise require either anterior resection or suboptimal endoscopic procedures.
