Anatomical Resection of Hepatocellular Carcinoma Located in a Deep Position of Segment 7 by Preoperative 3D-CT Simulation: A case report

Abstract

A 66-year-old man underwent follow up for chronic hepatitis type B and hepatocellular carcinoma, about 20 mm in size, was found. The preoperative liver function was ICGR15 15%. Liver damage A, and Child-Pugh score 5 points, class A. The clinical cancer stage was T1N0M0 stage I. The tumor was found deep in the liver, it is determined to be located in Segment 7 during preoperative simulation with 3D-CT. While it was difficult to identify the tumor during intraoperative ultrasonography, we identified segment 7 using counterstaining. We performed complete resection of liver segment 7. The patient was discharged on the ninth day after the operation without postoperative complications.
