  • Abstract
  • Look Inside

 Cases with adenoma and/or early cancer found by total colonoscopy were analysed (208 cases and 378 polys). The following results were obtained:

 (1) Smaller polyps were found distributed rather evenly throughout the large intestine.

 (2) Larger polyps especially early cancers were predominant at the left side colon and rectum.

 (3) Approximately 20% of all polyps and 10% of early cancers existed at the right colon.

 (4) Right-sided polyps were a quarter of all polyps.

 (5) Early cancers were found in 23% of patient with polyps. Fourteen of the total number of polyps were cancerous.

 (6) The rate of cancer among polyps was higher at the left-side colon.

Therefore, total colonoscopy was recommended for persons above fifty who consulted gastroenterologists.
