Objective:
To explore the operative methods and the effect of ano- reserving operations for lower rectal carcinoma (LRC) .Methods: Retrospective analysis was made on the clinical and pathological data of 206 LRC cases. Results:Of the 206 cases, 61 cases underwent Miles operation, 145 received ano-reserving procedures (ARP). In the 145 cases treated with ARP, postoperative anastomostic leakage occurred in 16 cases (11.0%),and anus stenosis in 13 cases (9.0%). All the complications were cured by non-operative treatment. There was no operative death in this series. The postoperative 5-year survival rate in Miles operation was 62.3%, in ano-reserving procedures was 67.2%( P>0.05). Conclusions:The choice of Miles opereration or ARP in the treatment of LRC is mainly according to patients condition. However, if a radical treatment can be assured. ARP is the best choice for LRC.
