Proctosigmoidoscopies of 6,293 patients revealed a 14.0% disease incidence, including polyps in 7.5% and cancer in 2.8%, with adenomatous polyps showing an age-specific distribution similar to large bowel cancer.

This retrospective study analyzed 7,679 routine proctosigmoidoscopies performed on 6,293 patients at Tohoku University Hospital between 1962 and 1974, reporting polyps in 470 patients (7.5%) and large-bowel cancer in 178 patients (2.8%). The authors also observed several other colonic conditions, including ulcerative colitis (129 patients), and rare cases of endometriosis coli (2 patients), along with melanosis coli and radiation proctitis. Among patients with polyps who underwent biopsy under observation (82.4% of 273 polyps over 1969–1974), 46.7% had adenomatous polyps, with age-specific distributions broadly consistent with those of cancer cases identified during 1962–1974. This paper does not explicitly discuss endometriosis or adenomyosis; it was included in the corpus via a keyword match in the upstream search index.

Abstract

7,679 proctosigmoidoscopies were performed on 6,293 patients during a period from 1962 to 1974 at the Third Department of Internal Medicine, Tohoku University Hospital. Results were summarized as follows: Polyps were observed in 470 patients (7.5%) and cancer was found in 178 patients (2.8%). 129 patients (2.0%) were observed to have ulcerative colitis. There were 57 patients with melanosis coli, 12 radiation proctitis, 7 amebic colitis, 5 granulomatous colitis, 2 endometriosis coli, 2 carcinoid and 2 intestinal tuberculosis. Thus, 879 out of 6,293 patients examined had some forms of disease, an over-all incidence being 14.0%. Biopsies were performed under the proctosigmoidoscopic observation in 82.4% out of 273 patients with polyps during the 6-year period from 1969 to 1974 and 105 patients (46.7%) were observed to have adenomatous polyps. The age-specific distribution pattern and incidences of these patients with adenomatous polyps were mostly consistent with those of 178 patients with cancer of the large bowel, which were observed by proctosigmoidoscopy during the 13-year period from 1962 to 1974. Thus, it is suggested that etiological correlation exists between polyps of adenomatous type and cancer of the large bowel.

Abstract

7, 679 proctosigmoidoscopies were performed on 6, 293 patients during a period from 1962 to 1974 at the Third Department of Internal Medicine, Tohoku University Hosptial. Results were summarized as follows: Polyps were observed in 470 patients (7.5%) and cancer was found in 178 patients (2.8%). 129 patients (2.0%) were observed to have ulcerative colitis. There were 57 patients with melanosis coli, 12 radiation proctitis, 7 amebic colitis, 5 granulomatous colitis, 2 endometriosis coli, 2 carcinoid and 2 intestinal tuberculosis. Thus, 879 out of 6, 293 patients examined had some forms of disease, an over-all incidence being 14. 0%. Biopsies were performed under the proctosigmoidoscopic observation in 82.4% out of 273 patients with polyps during the 6-year period from 1969 to 1974 and 105 patients (46.7%) were observed to have adenomatous polyps. The age-specific distribution pattern and incidences of these patients with adenomatous polyps were mostly consistent with those of 178 patients with cancer of the large bowel, which were observed by proctosigmoidoscopy during the 13-year period from 1962 to 1974. Thus, it is suggested that etiological correlation exists between polyps of adenomatous type and cancer of the large bowel. © Tohoku University Medical Press Favorites & Alerts Recently viewed articles - About this Journal The Tohoku Journal of Experimental Medicine (TJEM) was founded in 1920 by professors of Tohoku Imperial University, Medical School.
