    1. Local resection of Rectum tumors Peter M. Markus Elisabeth Hospital Essen Germany

    2. Rectum tumorsLocal resection Which tumors Size, Localisation, Histology local vs anterior resection How do I remove peranal (mucosectomy, full thickness), TEM

    3. Rektal tumors - How to threat - Lower third peranal Middle and TEM Upper third anterior wall up to 12 cm post. wall up to 15 cm, 1/3 circumference

    4. Indication for local resection- histology - • Ln-involvement • adenoma, high grade dysplasia 0 • T1 Ca low grade (G1, G2, -pL1, -pV1.) ~3% • local recurrence rate ~ 6 % (0-28%) • Matzel et al. Chirurg 2003 • Nascimbeni et al. Dis Colon Rectum 2004
