  • Abstract
  • Look Inside

 The authors analysed 1,272 adenomas and 690 arcinomas of the colon and rectum including 228 early carcinomas detected during a seven-year period from 1978 to 1985 at the Nogaki Hospital, Nagoya and evaluated screening efficiency by the results obtained.

 Early carcinomas accounted for 33% among all colorectal carcinomas, and 89% of them were located in the rectum and left colon distal to the splenic fiexure.

 Diagnostic procedures such as optical examlnation of the anal region, digital rectal examination, anoscopy, proctoscopy or proctosigmoidoscopy were able to pick-up 32% of the early carcinomas.

 Some of them were found incidentally during surigcal operations for anal diseases such as hemorrhoids etc. 68% of them were detected by barium enema or colonoscopy capable of investigating the entire colon.

 The authors feel strongly that a detailed screening with sequential use of colonoscopy and barium enema on the same day at a clinic is especially efficient in patients suspected of having a protruded lesion, and in cases of elderly people, or of patients who live a long way from the clinic.
