Double common bile duct, a rare anatomical variant of the bile tract. Case report

Abstract

the presence of a double common bile duct is an infrequent anatomical variant with less than 200 cases published in the literature to date, and preoperative studies that must be performed on patients are essential in order to have suspicion or diagnosis confirmed, not only of the anatomical variant, but of the associated pathology, these being choledocholithiasis and malignant pathologies of the biliary tree the most frequent. The case of an 81-year-old male is presented, with a history of cholecystectomy 20 years previos, with a diagnosis of obstructive icteric syndrome, and magnetic resonance cholangiography and ERCP studies that report choledocholithiasis, where he is taken to surgery and the presence of a double bile duct as a finding. Biliodigestive bypass was performed with satisfactory results, and the biopsy result was negative for malignancy.
