Update of the German Experience with Local Excision of Rectal Cancer

Wider experience with and more data on curative local excision and endoscopic polypectomy for invasive rectal carcinoma are reported. Good results are achieved if strict selection criteria are observed. This treatment modality requires careful histopathologic diagnosis and regular follow-up examinations at short intervals. An international registry for locally treated rectal carcinoma is proposed for the collection of more data.
