FEATURES AND SURGICAL TREATMENT OF EARLY RECTAL CARCINOMA

THE VALUABILITY OF INTRARECTAL ULTRASONIC EXAMINATION ON DETERMINATION OF THE TREATMENT

Abstract

Twenty eight early rectal cancers (11 mucosal and 17 submucosal ones) treated between January 1973 to October 1988 were retrospectively evaluated, which were found in 11 males and 17 females with the average age of 62.0 years. The half of the patients complained of bloody stool, while five had no symptoms. The mucosal cancers were located equally over the all rectal regions, but almost of all submucosal cancers were placed on the lower rectum. Almost of all mucosal cancers occurred as focal cancers in adenomas, and many of submucosal cancers did not have any adenomatous components.
Intrarectal ultrasonic examination was valuable in diagnosing the depth of invasion of early rectal cancer. Webelive that intrarectal ultrasonic examination is necessary for deciding the protocol of treatment for rectal cancers.
