Impact of Preoperative Planning Using Virtual Segmental Volumetry on Liver Resection for Hepatocellular Carcinoma

Abstract

Hepatectomy simulation in 3D predicted segmental liver volume and the resection margin accurately. This virtual method should contribute to preoperative planning to achieve safe, curative resection in HCC patients, whose hepatic function is compromised.

Hepatic resection versus transcatheter arterial chemoembolization for the treatment of hepatocellular carcinoma with portal vein tumor thrombus

“…The safety of liver resectional surgery has been improved with the use of liver volumetry and portal vein embolization. [30][31][32][33][34][35] It is now generally accepted that patients should receive HR for HCC irrespective of the number of tumors if there is a reasonable sized functional future liver remnant left behind. Similarly, resection for a single large HCC (>10 cm) has been reported to be associated with favorable long-term survivals.…”

Perfusion and drainage difference in the liver parenchyma: Regional plane in segment 6

“…The preoperative liver volume measurements based on 3D anatomy imaging have been shown to agree with the actual volume of the liver resected at operation (17)(18)(19). The median volume difference between the portalvein-based and hepatic-vein-based anatomies in S6 was 73 mL.…”

3D CT simulation in minimally invasive thoracic surgery

“…For such cases, sub-lobar resections are favorable both for oncological reasons and for the pulmonary functions preservation. For these patients, there developed several simulation software which process three dimensional images to find location of the target and indicate the precise safety margin from the cancer (13). Some software provided with the function which enables visualization of the intersegmental septa and, there are several reports of sublobar resections with the best use of this function (2,14).…”
