Clinical scenario :
A 27-year-old male with no significant comorbidities presented with a history of episodic, recurrent abdominal pain of 4 years duration. The patient described the pain as colicky, remaining for 1–2 hours necessitating intravenous analgesics predominantly in the upper abdomen. His abdominal pain had no reference or radiation and there was no jaundice associated with it. The patient had been admitted four times in various hospitals during this period and every time basic laboratory evaluation including liver function tests and serum amylase were within normal limits. His ultrasound examination had been within normal limits on each occasion he was hospitalized for his abdominal pain. The patient denied any high-risk behavior or drug abuse. Over this period he had a stable appetite and constant weight. On examination, he was conscious oriented and he had stable vitals. There was no icterus or lymphadenopathy. His systemic examination was unremarkable.
Evaluation and course :
Laboratory data revealed normal hemogram, normal liver function tests, and his abdominal ultrasound was also within normal limits. There were no eggs or ova in his stool examination. Keeping in view recurrent biliary colics magnetic resonance cholangiopancreatography (MRCP) was done which showed a doubtful filling defect in the common bile duct but intra-hepatic biliary radicals were not dilated. There were no gall stones and the rest of the viscera were within normal limits.
Endoscopic retrograde cholangiopancreatography (ERCP) was undertaken which revealed normal papilla. Selective common bile duct (CBD) cannulation was done and cholangiogram revealed a filling defect in the lower end of the common bile duct. There was mild dilatation of the common bile duct (Figure 1 however, biliary radicals were not dilated.
Sphincterotomy was done and CBD was swept with a biliary balloon and a live Fasciola hepatica was seen coming out of the common bile duct (Figure 2 and Fig 3)
Later using biopsy forceps the worm was taken out of duodenum and confirmation of the species, Fasciola hepatica was made by the microbiology department of the hospital. The patient was given two tablets of triclabendazole 250 mg (manufactured by Novartis) after the procedure. Following therapeutic ERCP patient became symptom-free and is attending our clinic for the last 24 months now.
Teaching message :
Fascioliasis is one of the unusual causes of recurrent biliary colics and it warrants a high degree of clinical suspicion especially in non-endemic areas. The current report emphasizes that ERCP may be considered for the management of recurrent biliary colics even though classical features of biliary obstruction may not be present.
