Abstract:Objective：To introduce a new anus preserving operation for low rectal cancer-ultralow anterior resection and colorectal/coloanal anastomosis by using supporting-bundling up method.
Methods：The clinical data of 310 patients who underwent anus preserving operation by supporting-bundling up method for low rectal cancer were retrospectively reviewed.
Results：The mean distance of tumor from the anal verge was 4.7±1.2cm; the TNM stage was stage Ⅰin 40 cases, stage Ⅱ30 cases, stage Ⅲ109 cases and stage Ⅳ 31 cases. the mean distance of the anastomosis from the anal verge was 2cm(1-4cm). the occurrence rate of postoperative anastomosis leak was 2.3%, the rate of excellent anal sphincter control was 82.25%. The 5-year local recurcence rate was 5.8%.
Conclusions：Ultralow anterior resection and colorectal/coloanal anastomosis by supporting-bundling up method may be one of the best anus preserving operations for low rectal cancer. It is a safe and feasible operation, and the long-term outcome is excellent.
