[Biliary ascariasis after cholecystectomy and papillotomy in a non-endemic area]
History And Admission Findings:
A 61-year-old woman was admitted to hospital with nausea and vomiting. Four years earlier she had undergone cholecystectomy and papillotomy.
Investigations:
Laboratory examination showed a slight increase of aspartate and alanine aminotransferase, glutamyl transpeptidase, and moderate eosinophilia. Ultrasound revealed an elongated echogenic structure within the common bile duct. At endoscopic cholangiopancreaticography (ERCP) a 23 cm-long Ascaris lumbricoides was found.
Treatment And Course:
The worm was removed endoscopically with forceps. Antihelmintic therapy with mebendazole was given. After that the patient was well and laboratory findings were normal.
Conclusion:
Biliary ascariasis should also be considered in a non-endemic area. Previous cholecystectomy and papillotomy are predisposing factors. In our case ERCP was the diagnostic and therapeutic method of choice.
