Aberrant right posterior sectoral duct injury necessitating liver resection.

Aberrant insertion of the right posterior sectoral duct is a particularly hazardous variation of biliary anatomy which makes it prone to injury during laparoscopic cholecystectomy. Such injuries are challenging to manage, as multiple therapeutic options are available with no clear consensus in the literature for an optimal approach. Options include conservative management, intraoperative ligation of the injured duct, Roux-en-Y reconstruction and segmental liver resection. Most cases in the literature advocate for nonoperative management or hepaticojejunostomy. We present an unusual case of aberrant right posterior sectoral duct injury in which neither of these approaches was viable, necessitating a bi-segmental liver resection.
