[A grenade splinter as the cause of cholangitis and icterus]

Forty five years after being injured by a grenade splinter a now 74-year old man suddenly developed colicky pain in the right upper abdomen, accompanied by colourless stools, jaundice and fever. The white cell count was 21,000/microliters, bilirubin was raised to 10.9 mg/dl, and ultrasound examination revealed a sharply circumscribed echo in the distal choledochal duct. Retrograde endoscopic cholangiography revealed a metal-dense concrement, presumably the nidus of gallstone formation. After endoscopic emptying of the bile duct the patient quickly improved so that cholecystectomy could be performed. The long symptom-free interval was most likely due to an at first peripheral position of the splinter in liver tissue. The secretory pressure of the liver cells then probably caused a slow migration into the choledochal duct.
