下部直腸癌의 腹背部術式

Abstract

From January 1988 to October 1990，14 patients with lower rectal cancer below the peritoneal reflection were treated by sphincter preserving surgery and postop radiation therapy. We performed abdominosacral resection in seven patients whose lower margin of the tumor was located at 6-9 cm from the anal verge and abdominotranssphincteric resection in seven patients whose lower margin was 3-6 cm from the anal verge without invasion of the sphincter muscle. Five of the 14 developed leakage at the anastomotic sites. Of four patients whose lower margin of the tumor was located at 3cm from the anal verge, two developed anal stenosis. There was no motality in these 14 patients. In conclusion, these procedures are considered most suitable for lower rectal cancers located below the peritoneal reflection. The complication rate should decrease as experience increases.
