Transanal Resection of Rectal Lesions

  • Shmuel Avital


There are two common techniques for transanal excision of anorectal lesions. Conventional transanal excision involves operation through the anal canal. Lesions that are more proximal, and therefore difficult to visualize and reach with conventional instrumentation, may be better suited for transanal endoscopic microsurgery (TEM). Indications include benign polyps and rectal cancers. Polyps are thoroughly investigated prior to embarking on transanal resection. Assessment may include biopsy, endoscopic ultrasound (EUS), CT or MRI, and/or serum tumor markers.
