ABSTRACT
Imperforate anus is a common anomaly associated with many other anomalies. The aim of this study is determining the frequency of associated anomalies in children with imperforated anus. This retrospective, cross sectional study was conducted over 245 neonates and children [137 male, 105 female and 3 ambiguous genitalia] with imperforated anus diagnosis, in Ali-Asghar Hospital 1999-2008. Our information was extracted from patients' records. SPSS 17 was used for data analysis. 50.6% of the patients had associated anomalies including 18% cardiovascular, 15.5% renal, 14.7% gastrointestinal, 13.9% vertebral, 13.1% genitourinary, and 8.2% external genitalia. The most prevalent associated anomaly was genitourinary system anomalies followed by cardiovascular anomalies. Patients with imperforated anus should undergo a detailed general physical, systemic and radiological examination [infant gram, echo cardiography, ultrasonography of urogenital system] in neonatal period for on time detection of associated anomalies
