Disorders of defecation in children

Abstract

In a series of 123 children with disorders of defecation, constipation was the main problem in 89 and fecal incontinence in 34. All but three of the latter also had constipation. The principal physical findings were abdominal protuberance with palpable stool in the bowel and the presence of a fecal mass in the rectal ampulla. Laboratory and radiologic findings were nonspecific except in two of the three patients found to have congenital megacolon (Hirschsprung's disease). Rectal suction biopsy, performed in 69 patients, was diagnostic in all three with Hirschsprung's disease. Anorectal manometry, done in 11 patients, was of limited value. In general, treatment consists of patience and understanding on the part of physician and family, a regimen of orally administered (noncathartic) laxatives with dose gradually reduced over weeks to months, frequent telephone communication between physician and parents, and occasional office visits. Patients with nonretentive fecal incontinence require an intensive psychologic approach. A patient, empathetic, and available physician is one of the most important ingredients in the treatment regimen.
