Conventional Transanal Excision: Current Status and Role in the Era of Transanal Endoscopic Surgery

Conventional transanal excision as originally described by Parks has been used for the local excision of both benign and malignant lesions of the rectum. Radical resections for rectal lesions are associated with higher perioperative morbidity and mortality including sexual and urinary dysfunction. Despite references to transanal resection of lesions up to 12cm from the dentate line, transanal endoscopic techniques originally developed by Buess in the 1980s afford much better visualization of the upper and middle rectum.
