Anorectal malformations

ABSTRACT

A total of 1326 patients with anorectal malformations were admitted to the department of paediatric surgery, Nishtar Medical College, Mutton, during January, 1984 to June, 1993. Amongst them, 990 were males and 336 were females; 862 patients had high [including intermediate] and 464 had low variety of anorectal malformations [ARM]. Two hundred and thirty seven [237] i.e. 17.88% babies had associated anomalies. Low variety cases were treated either by dilatations [77] or anoplasty [271] or cut-back [83] or anal transpositioning [33]. Patients with high variety underwent preliminary colostomy. A total of 102 pullthroughs were performed. Posterior sagittal anorectoplasty was performed in 61 cases. The remaining 41 cases underwent abdomino-sacro-parineal and sacro-perineal pullthroughs. Post-colostomy complications were seen in 115 out of 828 cases and pullthrough operation was followed by various complications in 33 patients. Mortality following pullthrough was 1.9%. Posterior sagittal anorectoplasty is safe and effective method of dealing with high and intermediate variety of anorectal malformations
