Gastroenterology clinical image challenge: A 40-year-old man was admitted to our hospital with sustained upper abdominal pain after dinner. He denied alcohol intake or taking any prescription or over-the-counter medications. He had undergone a laparoscopic cholecystectomy two years ago. A computed tomography scan demonstrated the acute pancreatitis companied with dilation common bile duct (CBD). Laboratory data revealed abnormal elevation of the serum bilirubin (53 μmol/L) and alanine transaminase (85.7 U/L) levels. Emergency endoscopic retrograde cholangiopancreatography was performed. The cholangiogram showed a spindle-shaped filling defect measuring 7 × 20 mm in the proximal CBD. Then an oval pearl-like material with smooth appearance was extracted by endoscopic retrograde cholangiopancreatography.
