Manometric evaluation of postoperative patients with anorectal anomalies.
OBJECTIVE
To evaluate the outcome of surgical treatment in patients with anorectal malformations and to correlate the clinical, manometric and electromyographic studies in assessment of postoperative continence in these patients.


METHODS
Forty-one patients operated on for anorectal malformations were evaluated retrospectively. These included 13 patients with low anomalies, 24 with high anomalies, and 4 with congenital pouch colon. Functional results after surgical correction were assessed on clinical basis using the Kelley's scoring system and by anorectal manometry. In addition, the electrical activity of contraction of the external sphincter muscle was studied using electromyography.


RESULTS
There was direct correlation between anal canal pressures and Kelley's score in patients with both high and low anomalies; Kelley's score of 6, 5, 4, 3 and less had pressures ranging between 60-75, 45-59, 30-44, 15-29 and less than 15 cm H2O, respectively. However, the electromyographic activity did not correlate well with Kelley's score.


CONCLUSIONS
Anorectal manometry correlates well with Kelley's scoring system and may be a more objective method of analyzing the results of surgery. Poor correlation between Kelley's score and electromyography may be a reflection of poor compliance with instructions to voluntarily contract the muscles of continence.
