Anorectal anomaly: a review of 82 cases seen at JUTH, Nigeria.
BACKGROUND
The management of anorectal anomaly remains a challenge to Surgeons. This study was carried out to determine the pattern and outcome of management of anorectal malformations (ARM) in a Nigerian tertiary hospital.


METHODS
The clinical and operative records of consecutive children with anorectal anomaly managed between October 1990 and September 2000 at the Jos University Teaching Hospital, Jos, were reviewed.


RESULTS
There were 82 patients, (57.3%) males and 35 (42.3%) females (m:f=1.3:1). There were 20 (24.4%) cases each of the high and intermediate types, 40 (48.8%) low variety and 2 (2.4%) cases of persistent cloaca. The high type was proportionately commoner in the males. Less than one-third presented within 24 hours. Eighty three percent of patients (mainly males) presented in acute intestinal obstruction. Passage of stools from abnormal sites and "imperforate" anus were complaints in 60 (73.1%) patients each. A total of 63 patients had definitive corrective procedure. Four patients with stenotic anus were treated by serial anal dilatations while 29 with low anomaly had anoplasty during the neonatal period. Twenty eight patients with intermediate or high anomalies or persistent cloaca had definitive repair or pull-through operations carried out 6-12 months after an initial colostomy. The definitive pull-through operations included abdominoperineal pull-through in 11 patients, PSARP in 15, while 2 girls with persistent cloaca had posterior sagittal anorectovaginoure-throplasty (PSARVUP). Twenty nine children were fully continent of stools after surgery; three patients developed occasional faecal soiling; while six patients had faecal incontinence.


CONCLUSIONS
Anorectal anomaly is common, but presentation is late in our environment. Although mortality rate was high (26%), early results of definitive operation among survivors were generally good after a mean follow-up period of 19 months.
