The use of intraoperative ultrasound (IOUS) allows us to perform new conservative hepatectomies. The investigators previously reported the systematic subsegmentectomy by IOUS-guided finger compression for segments 2-3, which is currently applied for patients with hepatocellular carcinoma (HCC)on cirrhosis. The investigators herein describe a novel technique, which consists in the systematic right posterior sectionectomy by IOUS-guided finger compression.
A novel technique for the demarcation of the resection area by means of IOUS-guided finger compression to accomplish a right posterior sectionectomy is described. Dissection or encirclement of the sectional pedicles for resection area demarcation is thus avoided. Ten patients underwent this technique successfully without mortality or major morbidity. IOUS-guided finger compression of sectional portal pedicle feeding the right posterior section is a feasible, safe, and effective method.

The technique consists in IOUS-guided finger compression of the right posterior portal pedicle at the level closest to the tumor but oncologically suitable. This method allows us to anatomically mark the area of resection with nor hilar plate nor IOUS-guided puncture of vessels, which are up to date the only two techniques available to perform anatomical right posterior sectionectomy - namely the removal of segment 6 and 7.
