IMMEDIATE AND LONG-TERM RESULTS OF SURGICAL-MANAGEMENT OF LOW IMPERFORATE ANUS IN GIRLS

Background: The majority of girls with imperforate anus are reported t o have a malformation of the low variety. Despite this, much of the li terature has focused on the more complex, high lesions. Methods: This study reviews our experience with 44 girls with low imperforate anus f rom a 22-year period. Results: The incidence of associated anomalies w as 61%, which is higher than generally reported. All patients in the s tudy had anal fistulae. Fifty-seven percent had perineal fistulae, 23% had fourchette fistulae, and 20% had vestibular fistulae. Cutback ano plasty was performed in 55%, Potts transfer anoplasty was used in 27%, and 18% of patients were treated with either limited posterior sagitt al anorectoplasty or anterior sagittal anorectoplasty. Surgical compli cations were uncommon. Long-term follow-up was carried out by telephon e survey. This showed 89% of the girls to be successfully toilet train ed. However, 47% of patients experience at least occasional soilage or episodic fecal incontinence. Conclusions: Low imperforate anus can be successfully treated using a variety of procedures without colostomy. Most girls with low imperforate anus are successfully toilet trained, but problems with continence persist in a significant number of these patients. Copyright (C) 1998 by W.B. Saunders Company.
