Abstract

OBJECTIVE:

Years after surgery for Hirschsprung's disease, many children continue to suffer from fecal incontinence or constipation. The purpose of the present investigation was to define the physiology underlying the persistent symptoms in children after surgery for Hirschsprung's disease, and to determine the outcome of interventions based on the results of the motility testing.

METHODS:

We studied 46 symptomatic patients (5.5+/-3.3 yr old, 35 male) >10 months after surgery for Hirschsprung's disease. We performed a colonic manometry with a catheter placed with the tip in the proximal colon. We used a structured questionnaire and phone interview to follow up the patients an average of 34 months after the manometry.

RESULTS:

We identified four motility patterns: 1) high-amplitude propagating contractions (HAPCs) migrating through the neorectum to the anal sphincter, associated with fecal soiling (n = 18); 2) normal colonic manometry associated with fear of defecation and retentive posturing (n = 9); 3) absence of HAPCs or persistent simultaneous contractions over two or more recording sites (n = 15), associated with constipation (n = 13); and 4) normal colonic motility and a hypertensive internal anal sphincter (>80 mm Hg) (n = 4). We based treatment on results of the motility studies. There was improvement in global health (mean score, 3.9+/-1.1 vs 2.8+/-1.3 at the time of initial evaluation, p < 0.001) and emotional health (3.8+/-1.1 vs 2.6+/-1.1, p < 0.0001). Improvement in the number of bowel movements occurred in 72% of children. Resolution or decreased abdominal pain was reported in 80%.

CONCLUSIONS:

Colonic manometry clarifies the pathophysiology and directs treatment in symptomatic children after surgery for Hirschsprung's disease.
