Frequency and findings of the acquired anorectal disease in the pediatric population with chronic constipation

To determine the frequency of anorectal disease associated with chronicconstipation in children we conducted an observational, descriptive,retrospective study. One hundred and sixty eight patients were evaluatedby anorectal manometry over a 10-year period. The population was dividedinto organic constipation (OC) and functional constipation (FC) per ROMEIII criteria. Of those: 95 (56.54%) presented with anorectal disease. The agerange was 1-17 (mean 5.3). Eighteen presented with OC and 77 with FC.Acute anal fissure was found in 45 patients (38 FC, 7 OC), chronic analfissure in 38 (30 FC, 8 OC), perianal erythema in 26 (23 FC, 3 OC), scartissue was found in 28 (24 FC, 4 OC), anal mucosa congestion in 27 (22FC, 5 OC), hemorrhoidal disease in 26 (20 FC, 6 OC) and perianal venousdilatation in 21 (16 FC, 5 OC). Anal fissure, perianal erythema, and venousdilation occurred more frequently in patients with an anterior ectopic anus. Ananal fissure was present in more than 80% of patients who had puborectalismuscle and external anal sphincter dysfunction.We concluded that the frequency of acquired anorectal disease in childrenwith chronic constipation is high; early diagnosis and treatment are prioritiesfor the successful management of these patients.
