FUNCTIONAL APPRAISAL OF LOW ANTERIOR RESECTION FOR RECTAL CANCER

During the eleven-year period from 1970 to 1981, 311 patients underwent primary operation for rectal cancer. Anal sphincter-saving operation was performed in 156 patients (147 of low anterior resection, 8 of pull-through method and 1 of abdomino-sacral method). One hundred and five of the 147 patients with low anterior resection had undergone curative resection and were studied as to function of defecation and urination, sexual potency and rehabilitation in this review.
Defecation function was evaluated by the following examination : The number of times, the rectal movement analyzed by 16mm X-ray cinematogram and anal contraction activity measured by intracanal pressure.
Although various differences in postoperative anal function were observed between those who had anastomotic site at more than 4cm oral from the anal verge and those with it within 4cm, long-term observation had revealed no difference between them.
Since lymphadenectomy of the obturator foramen has been carried out from 1976 disturbance of urination has necessarily occurred in most of the patients. But consequently self-urination recovered in all of them. Sexual impotency has been also observed in all of male patients, and this problem is still remained ulsolved.
