Coeliac and posterior pancreatico duodenal nodes are removed.* T2 - Cases Radical cholecystectomy involving removal of segment 4b and 5 along with nodes.* T3- Radical cholecystectomy or Extended Right Hepatectomy is done* If only segment 5 was involving removal of Segment 4b and 5 would have been done* Some cases will also require a central hepatectomy- Removal of segments 4, 5 and 8* Some cases will also need Right Trisegmentectomy- Removal of segments 5,6,7,8 and segment 4
