Development of black gallstones after the nonsurgical management of splenic injury: report of a case.

A 22-year-old man was admitted to our Emergency Department after suffering splenic injury in a traffic accident. His intraabdominal bleeding was treated nonsurgically by the administration of total parenteral nutrition (TPN) and blood transfusions of packed red cells. He presented again 2 months after his discharge, being 3 months after the injury, for right hypochondralgia, at which time a gallstone was demonstrated on ultrasound (US) and computed tomography (CT). After endoscopic laparoscopic cholecystectomy, his symptoms disappeared and he has remained well since. The clinical course of this patient indicates that hemolytic hyperbilirubinemia can cause black gallstones as a late complication of the nonsurgical management of abdominal blunt trauma.
