PROCTOSIGMOIDOSCOPY-INCIDENCE OF POLYPS IN 50,000 EXAMINATIONS

JAMA. 1957;163(6):411-413. doi:10.1001/jama.1957.02970410001001
Abstract

• Proctosigmoidoscopy was accomplished in 50,000 cases with but a single instance of perforation by observing these precautions: digital examination of the rectum before inserting the instrument, blind insertion of the instrument only as far as the finger has explored, infrequent use of air inflation, special care in passing diseased segments, and care not to push the instrument forcibly against the intestinal wall until the lumen ahead has been identified. All subjects were asymptomatic and between the ages of 20 and 76. Polyps were found in 3,952 cases. Of these, 328 were malignant. In addition, 19 cases of moderately advanced rectal cancer were also found. Digital examination and proctosigmoidoscopy are effective in early detection of cancer. The early removal of rectal polyps will prevent many carcinomas of the colon.
