Laparoscopic right posterior sectionectomy for a large hepatocellular carcinoma close to inferior vena cava.

Abstract

Approximately 20% of hepatocellular carcinomas (HCC) occur in noncirrhotic livers. Resection may be considered for patients with HCC, provided sufficient future liver remnant is available, regardless of the tumor size. Tumors located posteriorly near the right hepatic vein (RHV), or inferior vena cava can be managed through anterior or caudal approaches. RHV is typically conserved during right posterior sectionectomy. When a large posteriorly placed tumor causes chronic compression on RHV, the right anterior section drainage is redirected preferentially to the middle hepatic vein. The division of RHV in such instances does not cause congestion of segments 8 and 5. The technical complexity of laparoscopic right posterior sectionectomy arises from the large transection surface, positioned horizontally. We describe in this multimedia article, a case of large HCC in segments 6 and 7, which was successfully treated using laparoscopic anatomic right posterior sectionectomy.
