Twenty (7.2%) cases occurred in twin pregnancies and 24 (8.7%) with chromosomal anomalies\/genetic syndromes were excluded. There were 234 cases (total prevalence\u2009=\u20092.7, 95% confidence interval [CI]: 2.4, 3.1 per 10,000 live and stillbirths). There was no evidence of a trend in prevalence over time (Chi<jats:sup>2<\/jats:sup> test for trend: <jats:italic>p<\/jats:italic>\u2009=\u20090.789). There was a male predominance (70.9%). Of the 234 cases, 167 (71.4%) were live born, two (0.9%) were late miscarriages, seven (3.0%) were stillbirths, and 58 (24.8%) were terminations of pregnancy for fetal anomaly. There was no significant association with maternal age at delivery (<jats:italic>p<\/jats:italic>\u2009=\u20090.095). 7.2% of isolated cases (cases with no other congenital anomalies) were diagnosed prenatally.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSION<\/jats:title><jats:p>The prevalence of anorectal anomalies in this study is comparable to other case series.
