Abstract
High dorsal resection (HDR) of the liver is a systematic resection technique for hepatocellular carcinoma (HCC) arising in the caudate lobe. HDR is rarely performed, as the procedure requires a high level of operative skill, knowledge of liver anatomy and is performed in patients with limited hepatic function. Between 2002 and 2012, we performed HDR on 9 patients. The median operation time was 534 min (range, 349-903 min), and the median blood loss volume was 430 mL (range, 94-4,530 mL). The severe morbidity rate was 11.1%, but there was no operative mortality, and the median hospitalization was 13 days (range, 8-93 days). The overall survival was 49.7 months (range, 3.1-89.0 months). Despite the hard-to-approach anatomic location, HDR can be carried out safely with good survival compared to other segments.
