High dorsal resection for recurrent hepatocellular carcinoma originating in the caudate lobe.

Standards that enable surgeons to balance radical operative procedures with functional preservation for recurrent hepatocellular carcinoma (HCC) in the caudate lobe have not yet been established. A 54-year-old man with recurrent HCC originating in the caudate lobe was readmitted to our hospital. The combined resection of the adjacent hepatic parenchyma may have carried a risk of postoperative liver failure. The anterior transhepatic approach may have caused massive bleeding due to the presence of scarring from the previous hepatectomy. Therefore, we performed an isolated total caudate lobectomy, i.e., a "high dorsal resection" as a second hepatectomy. The postoperative course of the patient was uneventful, and there has been no local recurrence 1 year after the repeat hepatectomy. Indeed a "high dorsal resection" is rarely required, but it is still ingenious, and this surgical modality can balance the curability with the hepatic functional reserve even for recurrent caudate HCC in patients with liver cirrhosis.
