Clinical Importance of Surgical Treatment of Low Rectal Carcinoma in Anus-Preserving Procedure—an Analysis of 86 Cases

We investigated the methods and experiences of an anus-preserving procedure in curative resection of low rectal carcinoma. Eighty-six patients with low rectal carcinoma underwent Dixon's procedure with device assistance. Patients were then observed for the effects of operation. The operation was successful in all patients. Pathologic examination of specimens revealed negative margins. Complications such as anastomotic leakage were found in 7 cases. All patients recovered well. Device assistance may contribute to the successful performance of anus-preserving procedure in low rectal carcinoma. Whether the anus can be preserved or not depends on the accurate measurement of the distal length of the rectum. A meticulous hemostasis and avoidance of tension on the stoma are key measures for avoiding anastomotic leakage.
