Four patients who complained of symptoms and signs compatible with biliary tract disease and in whom the diagnosis of gallbladder (three cases) and common bile duct ascariasis (one case) was made sonographically are reported. In two patients with gallbladder ascariasis, cholecystectomy corroborated the presence of the round-worms, and was curative. The third patient was a pregnant woman (32nd gestational week) who took piperazine citrate, and a second sonogram performed 29 days later was completely normal. The fourth patient with common bile duct ascariasis underwent choledochotomy with extraction of one ascaris lumbricoides from the common duct, and a T tube was left in place for 15 days. All patients received antiparasitics and had a favorable outcome. Ultrasonography is an important noninvasive diagnostic procedure in the work-up of these patients, who usually describe a clinical picture suggesting gallstone disease: this is especially true in the presence of pregnancy.
报告了4例主诉有与胆道疾病相符的症状和体征的患者，经超声检查诊断为胆囊蛔虫病（3例）和胆总管蛔虫病（1例）。在2例胆囊蛔虫病患者中，胆囊切除术证实了蛔虫的存在，且具有治愈效果。第3例患者是一名孕妇（妊娠第32周），服用了枸橼酸哌嗪，29天后进行的第二次超声检查完全正常。第4例胆总管蛔虫病患者接受了胆总管切开术，从胆总管中取出1条蛔虫，并留置T管15天。所有患者均接受了抗寄生虫治疗，预后良好。超声检查是这些患者检查过程中的一项重要无创诊断方法，这些患者通常描述的临床表现提示胆结石疾病：在妊娠情况下尤其如此。
