  Purpose

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.

Groups/Cohorts Assigned Interventions
Right posterior section group
Patients with tumors in the right posterior section of the liver (segments 6-7)
Procedure: Anatomical right posterior sectionectomy of the liver by IOUS-guided finger compression.
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.
Other Name: anatomic resection of segment 6-7

Detailed Description:

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.

  Eligibility

Ages Eligible for Study:   18 Years to 85 Years
Genders Eligible for Study:   Both
Accepts Healthy Volunteers:   No
Sampling Method:   Non-Probability Sample
Study Population

The study population include patients with primary or secondary liver tumors in the right posterior section of the liver eligible to a right posterior sectionectomy as a primary surgical procedure.

Criteria

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.
