[Biliary fistula after concealed choledochal rupture in a polytraumatized patient]

This paper describes the case of a polytraumatised patient. Following primary care, a persistent fistulous wound developed. After initially good healing, the patient progressively deteriorated. Extensive diagnostic workup revealed a maximally elevated bilirubin concentration in the wound secretion. Five years previously, the patient had undergone a cholecystectomy. A leak in the common bile duct caused by the trauma was detected and was treated with a biliodigestive anastomosis with a Roux-Y loop, and bypass of the distal common bile duct.
