Ultrasonically guided subsegmentectomy.

TLDR

The study introduces a novel ultrasound‑guided systematic subsegmentectomy technique. The procedure uses intraoperative sonography, ultrasound‑guided puncture with dye injection, and hemihepatic blood occlusion to perform systematic subsegmentectomy, which was applied to 57 patients with no operative deaths. In 35 hepatocellular carcinoma patients, the one‑year, two‑year, and three‑year survival rates were 80.3%, 63.3%, and 52.6%, respectively.

Abstract

A new operative procedure for systematic subsegmentectomy guided by ultrasound has been described. This operation consists of operative sonography, ultrasonically guided puncture and injection of dye and hemihepatic blood occlusion. Systematic subsegmentectomy was performed upon 57 patients without operative mortality. The cumulative one year survival rate of 35 patients with hepatocellular carcinoma who underwent operation at our hospital was 80.3 per cent. The two and three year survival rates were 63.3 and 52.6 per cent, respectively.
