Surgery for Hepatocellular Carcinoma Located in the Caudate Lobe

Tumors were located in the Spiegel lobe in three patients, the caudate process in six, and the paracaval portion in three. The procedure performed most was isolated partial caudate lobe resection (six patients). Three patients underwent partial caudate lobe resection combined with other hepatectomy, and the remainder underwent total caudate lobe resection combined with other hepatectomy. Tumors of the patients who underwent combined total caudate lobe resection were mainly in the paracaval portion. The median operating time for the six patients who underwent combined resection was 400 min, and their median intraoperative blood loss was 1,683 ml. There were no postoperative complications in patients who underwent combined total caudate lobe resection, except one case of total resection combined with central bisegmentectomy. In that case, the remaining right posterior sector was twisted after liver extraction, causing blockage of the outflow of the right hepatic vein. The overall and recurrence-free survival rates did not differ between the isolated and combined resection groups.
