Abstract
Thirty-two patients with rectal cancer underwent local excision according to Y. Mason’s procedure. Since local excision does not remove lymph nodes, the risk of metastases must be minimal and therefore the selection of patients careful. Preoperative selection is performed by rectal digital examination, endoscopy, rectal endosonography and sometimes by magnetic resonance imaging. The validity of the local excision can only be established by the definitive postoperative histological assessment. In case of pT1 tumors with ‘low-risk’ histology, results show that survival and local recurrence rate are comparable to those obtained with radical resection.
