Abstract
In 20 post-mortem dissections, the subvesical bile duct of Luschka was noted in six specimens. Microscopic examination of ten other post-mortem gallbladders revealed small bile ducts on the gallbladder surface in five. Four cases of injury to the duct of Luschka during cholecystectomy are described and illustrated with cholangiographic and histological evidence. Post-cholecystectomy bile leaks from the drain tube, which closed spontaneously without sequelae, were noted in 9 per cent of 204 randomly selected cases and were regarded, at least in some, as being caused by a divided duct of Luschka. The practical significance of this duct during cholecystectomy is to keep close to the gallbladder wall during removal of the gallbladder, and to ligate a divided bile duct of Luschka if recognized at surgery.
