[Anorectal manometry. Practical use in a pediatric surgical clinic]

Over a series of 158 cases of anorectal manometry the authors describe the technique used in a general pediatric surgery department. Results are reported in Hirschsprung's disease specially in the neonatal period, chronic constipation, fecal incontinence after anorectal malformations and meningomyelocele, encopresis. Biofeedback was performed in 28 patients. Technique varies with the etiologies and results are reported. Anorectal manometry to be effective must be simple, reliable, safe and non invasive. The reported technique seems effective for this goal.
