The protocol presents a step-by-step laparoscopic protocol for radical resection of Bismuth-Corlette type IIIb perihilar cholangiocarcinoma. The procedure integrates preoperative PTCD, complex vascular dissection and repair, and biliary reconstruction for application in high-volume hepatobiliary centers.
FAQs
The hepatogastric ligament extends between the liver and the lesser curvature of the stomach, whereas the hepatoduodenal ligament continues toward the first part of the duodenum. Their different attachments help organize neighboring organs and create distinct pathways for vessels, nerves, lymphatics, and connective tissue within the peritoneal arrangement.
The hepatoduodenal ligament encloses the hepatic artery, portal vein, and bile duct, placing three essential structures together in a recognizable anatomical region. This relationship helps explain how blood vessels and bile drainage are organized near the liver and provides an important reference point when interpreting upper-abdominal anatomy or considering access to these structures.
The peritoneal layers create organized surfaces and connective pathways around the upper abdominal organs. Because the lesser omentum forms a boundary around the lesser sac, fluid or disease processes may be guided or contained by these anatomical relationships. Understanding the boundaries therefore helps relate peritoneal structure to patterns of movement and spread.
By contributing a boundary around the lesser sac, the lesser omentum separates and organizes spaces behind the stomach and near the liver and duodenum. This spatial arrangement supports interpretation of how organs relate to one another and why fluid movement or disease involvement may follow defined anatomical planes rather than spreading randomly.
Its importance in surgery comes from the concentrated arrangement of structures within the hepatoduodenal ligament. The bile duct, hepatic artery, and portal vein lie together there, while the surrounding peritoneal layers provide an anatomical route to the region. Recognizing these relationships helps surgeons orient access to biliary and hepatic vascular structures.
A useful approach is to trace its attachments from the liver toward the stomach and duodenum, then identify the structures traveling within its peritoneal layers. This connects organ position with vascular, neural, lymphatic, and connective-tissue pathways, giving anatomy students and researchers a framework for interpreting fluid movement, disease spread, and surgical relationships.
