Subvesical bile ducts of Luschka were first described by the German anatomist Herbert von Luschka in 1863.1In the strictest definition, these ducts usually range in size from 1 to 2 mm in diameter and course through the gallbladder fossa to empty into the right hepatic or common hepatic duct.2While ducts of Luschka are present in 3% to 5% of cadavers at autopsy,3their true incidence is unknown. Recent articles describe symptomatic biliary leaks in approximately 0.1% to 0.5% of patients after open cholecystectomy.4Of these symptomatic leaks, approximately 15% to 20% are attributed to ducts of Luschka.4Identifying intraoperative damage to a duct of Luschka is difficult. Keeping close to the gallbladder wall during dissection is the best way to prevent injury. A careful visual inspection of the gallbladder fossa at the end of the operation may confirm the presence of a biliary leak.2Placing a dry gauze pack in the gallbladder fossa and inspecting it for bile staining is a useful maneuver in open procedures. If an injury is identified during the operation, ligation of the divided bile duct is indicated.2Owing to the small size of these ducts, most symptomatic leaks do not manifest until several days postoperatively. Many go unrecognized and resolve without intervention.
