During the past 9 years the autonomic nerve preserving operation was performed for 375 cases of rectal cancer in order to reduce the postoperative urinary and male sexual dysfunctions. The suvival rates and the local recurrence rates of the cases of the autonomic nerve preserving operation were compared with those of the extended radical operation. And the indication for the autonomic nerve preserving operation was discussed.<BR>Five year and nine year survival rates of the overall cases of the autonomic nerve, preserving operation were 77.7% and 70.3%, respectively, whereas those of the extended radical operation were 62.3% and 57.2%, respectively.<BR>Five year and nine year local recurrence rates of the automomic nerve preserving operation were 12.6% and 13.9%, respectively, whereas those of the extended radical operation were 23.1% and 24.7%, respectively. According to the clinicopathological factors such as the location, the lymph node metastasis, the depth of invasion and the type of histological diagnosis, the both groups were divided and the survival and local recurrence rates were compared.<BR>As a result, the survival and the local recurrence rates of the each group of the autonomic nerve preserving operation were better than or almost the same as those of the case of the extended radical operation. Among then, 5 year suvival and local recurrence rates of intramuscular well-defferentiated adenocarcinoma of rectum without lymph node metastasis were 95% and 8%, respectively. And these cases are indication for the autonomic nerve preserving operation. As to the more advanced cases, as the local recurrence rates of the autonomic nerve preserving operation were about 20%, much more effort to obtain the radicality and curability are required without being statisfied with the better result than the extended radical oper ation and, if possible, the autonomic nerve preserving operation including partial preservation is recommended.
