Rouviere's sulcus
Pronunciation: roo-vee-AIRZ
Anatomical groove on the liver surface that serves as a landmark during laparoscopic cholecystectomy for identifying the hepatocystic triangle.
Full Definition
A consistent anatomical landmark located on the posterior aspect of segment VI of the liver, running parallel to the portal vein. During laparoscopic cholecystectomy, Rouviere's sulcus serves as a crucial reference point for safe dissection and helps identify the correct plane for achieving the critical view of safety. The sulcus typically contains small vessels or bile ducts and its identification helps prevent inadvertent injury to major hepatic structures during dissection of Calot's triangle.
Usage
Usage note: Named after Henri Rouviere; capitalize when referring to the eponym.
