Popis: Indications and results of local excision of rectal lesions are currently under debate. Transanal endoscopic microsurgery (TEM), allowing a precise, full-thickness excision, could improve oncological results in early rectal tumors. A prospective database was analyzed with the intent to identify risk factors for recurrence after TEM. Among 355 patients subjected to TEM, 107 had an adenocarcinoma: 48 pT1, 43 pT2, and 16 pT3. Comparing pre- and postoperative data, histological discrepancy was 20% and staging discrepancy was 34%. Mortality was nil, morbidity was 9%. Mean follow-up was 54.2 months (range = 12–164), follow-up rate was 100%. The 5-year disease-free survival rate was 85.9, 78.4, and 49.4% for pT1, pT2, and pT3, respectively (p = 0.006). Recurrence rate was 0% (0/26) in pT1sm1 cancers and 22.7% (5/22) in sm2-3 (p
