Abstract

In performing PD, it is very important to understand the running and anatomy of the hepatic artery and the positional relation with the tumor before surgery, leading to planning a proper surgical procedure. In this case series, we report 2 cases in which radical resection was achieved by pancreaticoduodenectomy(PD)with combined hepatic artery resection(without reconstruction)while paying attention to the positional relationship between the bifurcated hepatic artery and the tumor in the head of the pancreas. Case 1: A 73-year-old man. He visited the hospital with jaundice and was diagnosed with distal bile duct cancer. Preoperative contrast-enhanced CT showed that the replaced right hepatic artery(RRHA)was involved by the tumor. Intraoperatively, it was confirmed by ultrasonography that the arterial blood flow in the right lobe of the liver was flowing from the left hepatic artery through the hepatic hilar plate after clamping the right hepatic artery. Thus, PD with combined RRHA resection(without reconstruction)was performed. After the operation, there was no problem with hepatic artery blood flow, and R0 resection was achieved. Case 2: A 65-year-old man. He visited the hospital with jaundice as the chief complaint and was diagnosed with pancreatic head cancer with encasement in the proper hepatic artery(PHA). In this case, the right hepatic artery branches from the SMA and the left hepatic artery branches from the left gastric artery. Intraoperative findings showed no problem with hepatic artery blood flow even after test-clamping the common hepatic artery, and the common hepatic artery was not reconstructed. There is no postoperative complication, and R0 resection was achieved pathologically. Conclusion: For pancreatic head tumors with hepatic artery infiltration, it is important to understand the anatomy of hepatic artery preoperatively and to confirm the intraoperative blood flow. In such cases, pancreaticoduodenectomy with hepatic artery resection may contribute to achieving R0.
