Rouviere's Sulcus
traditional anatomy method
Rouviere's sulcus is a 2 to 5 cm sulcus running to the right of the liver hilum anterior to the caudate process and usually containing the right portal triad or its branches.Dissection may be started safely by division of the peritoneum immediately ventral to the sulcus and continued in a triangle bounded by the liver surface, the neck of the gallbladder and the plane of the sulcus.
Ratcheted grasper is inserted through the lateral 5-mm port to retract the gallbladder fundus in cephalad fashion. An atraumatic grasper is inserted through the middle 5-mm port to retract the gallbladder infundibulum laterally, exposing the anteromedial aspect of the triangle of Calot.
