Anatomic, isolated complete caudate lobectomy using an anterior transhepatic approach with glissonian pedicle approach and indocyanine green fluorescence guidance: a case report

Hepatocellular carcinoma (HCC) in the caudate lobe presents surgical challenges due to the lack of distinct anatomical landmarks. This case report introduces a novel surgical approach combining Takasaki's classification and indocyanine green negative counterstaining for precise anatomical caudate lobectomy. A 78-year-old patient with hepatocellular carcinoma in the caudate lobe underwent surgery following preoperative volumetric assessment. The method involved a glissonian approach for both left and right pedicles, coupled with meticulous dissection of hepatic pedicles of the caudate lobe guided by taping of left and right glissonian pedicles, followed by indocyanine green administration for improved visualization of caudate lobe boundaries. The procedure enabled complete tumor resection with minimal blood loss. At 50 months postsurgery, the patient maintains favorable liver function and performance status. This innovative approach offers a promising solution for precise resection of caudate lobe hepatocellular carcinoma, potentially improving surgical outcomes and long-term prognosis.
