Biliary ascariasis is not an uncommon paediatric problem in Cape Town. Real-time ultrasound examination offers a rapid method of diagnosis and treatment monitoring. In transverse scans, a 'triple echo' of gallbladder, dilated main bile duct and portal vein can be recognized. The worm gives an intense 'bull's-eye' echo within the duct and its tubular structure can be followed ultrasonically.
胆道蛔虫病在开普敦是一个常见的儿科问题。实时超声检查提供了一种快速的诊断和治疗监测方法。在横向扫描中，可以识别出胆囊、扩张的胆总管和门静脉的“三重回声”。蛔虫在胆管内产生强烈的“靶心”回声，并且可以通过超声追踪其管状结构。
