Epidemiologic aspects of complete rectal prolapse.

BACKGROUND AND AIMS: This study was undertaken to find out the incidence of rectal prolapse.

MATERIAL AND

METHODS

Ninety-nine patients operated on for rectal prolapse at Jyväskylä Central Hospital were studied. Patients operated between 1988 and 1998 were studied retrospectively from hospital records using chart review and thirty-five patients operated on between 1999 and 2002 were studied prospectively using our proctologic database.

RESULTS

The annual incidence of diagnosed complete rectal prolapse in the district of Central Finland was mean 2.5 (range, 0.79-6.08) per 100 000 population. There were ten men (10 percent) and 89 women (90 percent). Median age of the patients was 69 (range, 21-91) years. Forty-eight percent of the patients had concomitant cardiovascular disease and 15 percent psychiatric illness. Anal incontinence affecting quality of life was seen in 64 percent and constipation in 72 percent of patients. Constipation tended to be more attributed to difficult evacuation (72 percent) than to impaired bowel action (18 percent).

CONCLUSION

The annual incidence of rectal prolapse is 2.5 per 100 000 population. Rectal prolapse is associated with anal incontinence and constipation in majority of patients.
