Highlights • Aberrant subvesical bile ducts are a rare anatomical variation defined as a network of bile ducts located in the peri-hepatic tissue of the gallbladder fossa. • Their injury is almost inevitable and it leads to bile leakage, which is a life-threatening complication of laparoscopic cholecystectomy. • Meticulous operative technique and detailed exposure of the operative field is the cornerstone of a safe laparoscopic cholecystectomy, when surgeons encounter this rare anatomical variation. Introduction Aberrant subvesical bile ducts are a scarce anatomical variation, consisted by a network of bile ducts located in the peri-hepatic capsule of the gallbladder fossa. These rare ducts are usually discovered intraoperatively and their presence poses the risk of bile injury and clinically significant bile leak. Presentation of case Aberrant subvesical bile ducts were unexpectedly identified in a young woman during laparoscopic cholecystectomy. These three ducts were clipped carefully for avoidance of bile duct injury and subsequent bile leak. The operation was uneventful. A meticulous review of the recent literature was conducted as well. Discussion This unusual anatomical variation of the biliary tract is mainly discovered during the operation. Thus, surgical injury of these ducts is nearly inevitable and it provokes the severe complication of bile leak. Bile injury represents the most crucial and life-threatening postoperative complication of cholecystectomies. Surgeons in the right upper quadrant of the abdomen should be constantly aware of this rare anatomical variation. Conclusion Aberrant subvesical bile ducts are associated with a high risk of surgical bile duct injury. Nevertheless, meticulous operative technique combined with surgeons’ perpetual awareness concerning this peculiar anatomical aberration leads to a safe laparoscopic cholecystectomy.
