PATIENT PRESENTATIONA 51‐year‐old man without a past medical history presented to our emergency department with 2 months of intermittent epigastric pain radiating to the back, tan stools, fatigue, and weight loss. He denied current alcohol use. He appeared diffusely jaundiced. His abdomen was soft with mild epigastric tenderness and a negative Murphy sign. Serum analysis showed total bilirubin 13.7, aspartate transaminase 207, alanine transaminase 463, alkaline phosphatase 634, lipase > 4000, elevated carcinoembryonic antigen/carbohydrate antigen 19‐9, and negative hepatitis panel. Imaging included point‐of‐care (POC) ultrasound (Figure 1, Video 1), computed tomography (CT; Figure 2), magnetic resonance imaging (MRI; Figure 3), and endoscopic retrograde cholangiopancreatograph (ERCP; Figure 4).1FIGUREPoint‐of‐care ultrasound: Gallbladder (star), pancreatic duct (arrow), and common bile duct (circle).1VIDEOPoint‐of‐care ultrasound of pancreas revealing double duct sign.

Abbreviation: MRI, magnetic resonance imaging.4FIGUREEndoscopic retrograde cholangiopancreatography: Duodenum ulcer.DIAGNOSISDouble duct signOur patient had obstructive jaundice. POC ultrasound revealed a distended gallbladder with sludge without signs of acute cholecystitis. The dilated common bile duct >10 mm (normal < 6 mm) and dilated pancreatic duct >5 mm (normal < 3 mm) were consistent with the rare
