[Anastomosis techniques in deep rectal resection].

Low anterior resection is defined as a procedure restoring continuity when rectal cancer is located within 12 cm of the dentate line. Rates on anastomotic leakage are similar for stapled and sutured anastomoses. Critical for the success of either procedure are sufficient mobilisation of the left hemicolon to achieve tension-free anastomosis, precise lymphadenectomy according for these standards of surgical oncology and adequate vertical and horizontal dissection of tissue adjacent to the tumor. The local recurrence rate is determined by tumor stage an safety margin.
