Duplication of the common bile duct associated with dorsal pancreas agenesis: a diagnostic enigma and a major therapeutic turning point.

We present a pioneering case of a duplication of the common bile duct associated with agenesis of the dorsal pancreas in a 66-year-old man. After an episode of cholestatic jaundice, radiological investigations revealed complex vascular and biliary anomalies, redefining the therapeutic strategy. Instead of risky surgery, endoscopic biliopancreatic drainage resolved the symptoms. This rare and complex case offers new perspectives for the management of such anomalies, underlining the importance of a personalized, multidisciplinary approach.
