In this report, we present a 38-year-old female with acute cholecystitis, in which an aberrant right hepatic duct draining directly into the cystic duct was revealed by intraoperative cholangiography during a laparoscopic cholecystectomy. This anomaly was classified as the class V variant using the Hisatsugu classification schema, which has an incidence of 1.02%. The use of Strasberg’s critical view of safety has become ubiquitous in laparoscopic cholecystectomy. Intraoperative cholangiography provides and additional layer of safety, and should be considered as a routine practice, particularly when imaging to delineate biliary anatomic aberrancies has not been performed prior to surgery.
Key Words: Aberrant right hepatic duct, Cholangiography, Critical field of view, Laparoscopic cholecystectomy.
