The patient was 82 years old male. He was admitted with a complaint of narrowing of the stool, and was incidentally pointed out a 25mm wide basal elevated lesion with an irregular surface in the gallbladder body, by enhanced CT scan. We strongly suspected the gallbladder cancer. Unlike the normal anatomy, because the round ligament was located on the right side of the middle hepatic vein, and portal vein of the dorsal anterior segment was branched from the vincity of the umbilical portion, he was diagnosed with the right sided round ligament. Also intrahepatic bile ducts mutation was found. We performed the open cholecystectomy, and found that the gallbladder bed was on the left paramedian region of the liver and the calot triangle was covered by the body of gallbladder. The histopathological diagnosis was T2 (SS) N0M0 pStage II. 4 years and 6 months after the surgery, he is alive without recurrence.
The right round ligament is a rare anatomical mutation that accounts for 0.2-1.2%, and there are few reports of resection of gallbladder cancer with the right round ligament. It was considered to be a valuable case, and we reported it with some review of the literature.
