摘      要：BACKGROUND A right-sided round ligament(RSRL)is a rare,congenital anomaly of the intrahepatic portal vein,with a reported frequency of 0.2%-1.2%.For patients with perihilar cholangiocarcinoma associated with an RSRL,an accurate understanding of the vascular and biliary anatomy is *** SUMMARY We report a 70-year-old male with perihilar cholangiocarcinoma associated with an *** percutaneous transhepatic embolization of the left and anterior portal branches,we conducted a left trisectionectomy of the liver with extrahepatic bile duct resection and *** postoperative course was uneventful,and R0 resection was *** the liver volume of each section was compared between 7 patients with an RSRL and 20 patients with normal portal vein anatomy,the posterior section in RSRL patients was significantly larger than that in patients with normal portal vein anatomy(median:457 mL vs 306 mL,P=0.031).In patients with perihilar cholangiocarcinoma associated with an RSRL,left trisectionectomy has several surgical advantages:(1)The posterior branch of the portal vein often ramifies independently,and the division of the portal vein is easily conducted;(2)A relatively large amount of remnant liver can be retained;and(3)The anatomy of the posterior branch of the Glissonian pedicle is similar to that in patients with normal *** In patients with an RSRL and perihilar cholangiocarcinoma that does not involve the posterior section,left trisectionectomy may be a favorable choice.
