In this case report we document an unusual variant of common bile duct duplication in a 79-year-old man who underwent a pancreaticoduodenectomy for ampullary cancer. The duplication consisted of two unseparated, completely-layered, common bile ducts which originated above the cystic duct junction and terminated prior to the point of insertion into the pancreas, where the two lumens converged into a single duct. Duplication of the bile duct is rare and often goes undetected. In the present case, the anomaly was found incidentally in a patient who had a pancreaticoduodenectomy for an ampullary carcinoma. However, duplication may be associated with choledocholithiasis, cholangitis, pancreatitis, and pancreaticobiliary malignancies and it is important to be aware of the condition.<\/jats:p>","DOI":"10.22551\/2024.43.1102.10289","type":"journal-article","created":{"date-parts":[[2024,8,7]],"date-time":"2024-08-07T08:05:14Z","timestamp":1723017914000},"page":"56-60","source":"Crossref","is-referenced-by-count":1,"title":["An unusual variant of Type I common bile duct duplication associated with ampullary carcinoma"],"prefix":"10.22551","volume":"11","author":[{"name":"Department of Cellular Pathology, Nottingham University Hospitals NHS Trust, Queen\u2019s Medical Centre, Nottingham, UK","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Andrei","family":"Bancu","sequence":"first","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Thomas","family":"Poundall","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Clinical Radiology, Nottingham University Hospitals NHS Trust, Queen\u2019s Medical Centre, Nottingham, UK","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"given":"Claudia","family":"Santos","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]},{"name":"Department of Cellular Pathology, Nottingham University Hospitals NHS Trust, Queen\u2019s Medical Centre, Nottingham, UK","sequence":"additional","affiliation":[],"role":[{"role":"author","vocabulary":"crossref"}]}],"member":"9837","published-online":{"date-parts":[[2024,6,30]]},"reference":[{"key":"ref0","doi-asserted-by":"publisher","unstructured":"\"1.
