Abstract

Background: Anterior anus (AA) is a congenital anatomical variant with unclear clinical implications and management strategies. This study evaluated the clinical features, associated anomalies, and outcomes of AA in female infants.

Methods: This multicenter retrospective cohort study included infants diagnosed with AA between 2020 and 2024 at six tertiary referral centers in South Korea. The clinical characteristics, coexisting anomalies, and outcomes including constipation and urinary tract infections were analyzed.

Results: Among the 64 patients included in this study, 51.6% had a concomitant perineal groove. Congenital heart diseases were the most common coexisting anomaly, occurring in 32 patients. During a mean follow-up of 22.9 months, constipation was observed in 23% of the patients. Urinary tract infections were not observed. The perineal groove resolved spontaneously in 87.9% of cases.

Conclusion: AA is a benign anatomical variant that does not increase the risk of constipation or urinary tract infections. Given the observed association with congenital heart disease, cardiac evaluation should be considered when clinically indicated.

女婴前肛门的临床特征和预后：一项多中心回顾性队列研究。

背景：前肛门（AA）是一种先天性解剖变异，临床意义和治疗策略尚不清楚。本研究评估了女婴AA的临床特征、相关异常和预后。方法：这项多中心回顾性队列研究纳入了2020年至2024年间在韩国6个三级转诊中心诊断为AA的婴儿。分析两组患者的临床特点、并发异常及便秘、尿路感染等结局。结果：本组64例患者中，51.6%伴有会阴沟。先天性心脏病是最常见的共存异常，共32例。在平均22.9个月的随访期间，23%的患者出现便秘。未观察到尿路感染。87.9%的会阴沟自行消退。结论：AA是一种良性的解剖变异，不会增加便秘或尿路感染的风险。鉴于观察到的与先天性心脏病的关联，临床指征时应考虑心脏评估。
