The Cystohepatic Septum: Anatomical Findings and Surgical Considerations

Abstract

A CHS of variable length was identified in a large percentage of cadaveric dissections. This finding has important implications for surgical interventions on the biliary tract such as choledochotomy for common bile duct exploration, transcystic bile duct exploration, or bilioenteric anastomosis. The presence of a CHS may also represent an anatomic factor predisposing to Mirizzi's syndrome.
