Summary
Brief summary (as posted)
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.

Show eligibility criteria text
Inclusion Criteria: * Patients with tumors at least at 1 cm distally to the bifurcation of the right portal vein (bifurcation of P5-8 and P6-7) eligible for right posterior sectionectomy, namely the anatomical removal of segment 6 and 7, were considered potential candidates to this procedure. Precisely, these criteria were adopted: * Patients with hepatocellular carcinoma (HCC) with infiltrative growing pattern in contact with P6-7; * Patients with any type of HCC in contact with P6-7 with distal bile duct dilation; * Patients with colorectal liver metastasis (CLM) in contact with P6-7. Exclusion Criteria: * Exclusion criteria for carrying out the herein described procedure was considered the presence of tumoral thrombosis in P6-7.
