Two-stage hepatectomy with or without portal vein embolization allows to treat multiple bilobar metastases expanding surgical indications for these patients. However, it has some related drawbacks: two operations are needed, and some patients do not complete the treatment strategy for disease progression. Using experience gained from our ultrasound guided resection policy we explored the safety and effectiveness of one-stage surgical procedures in patients otherwise recommended for the two-stage approach.

Condition Intervention
Colorectal Cancer Liver Metastases Procedure: One-stage ultrasound guided hepatectomy

Study Type: Observational
Study Design: Observational Model: Cohort
Time Perspective: Prospective
Official Title: One-Stage Ultrasound-Guided Hepatectomy for Multiple Bilobar Colorectal Metastases: a Feasible and Effective Alternative to Two-Stage Hepatectomy

Further study details as provided by University of Milan:

Primary Outcome Measures:
  • The primary outcome was the safety of the procedure. To this purpose we studied morbidity, mortality, amount of blood loss, rate of blood transfusions, and postoperative trend of liver function tests. [ Time Frame: 30-day and 90-day postoperatively ]

Secondary Outcome Measures:
  • The secondary outcome measure was the reliability of the procedure from an oncological standpoint. For this purpose we studied the rate of true local recurrence (cut-edge) after a minimum follow-up of 6 months. [ Time Frame: Minimum Follow-up of 6 months ]

Enrollment: 19
Study Start Date: September 2001
Study Completion Date: December 2007
Primary Completion Date: May 2007 (Final data collection date for primary outcome measure)
Groups/Cohorts Assigned Interventions
Prospective cohort of consecutive patients who undergo surgery for colorectal cancer liver metastases
Procedure: One-stage ultrasound guided hepatectomy
Surgical strategy was based on tumor-vessel relationship at intraoperative ultrasonography (IOUS)and on findings at color-Doppler IOUS.

Study Population
Patients carriers of colorectal cancer liver metastases

Inclusion Criteria:

  1. Patients presenting with resectable colorectal cancer liver metastases (CLM)
  2. 4 or more lesions
  3. Bilobar involvement of the liver
  4. Contact or close adjacency (less than 0.5 cm) of at least one CLM with major intrahepatic vascular structures (1st or 2nd order portal branches and/or hepatic vein at caval confluence).

Exclusion Criteria:

  1. Patients with 3 or less resectable CLM
  2. Patients with 4 or more resectable CLM but nor bilobar
  3. Patients with 4 or more bilobar resectable CLM without any lesion presenting condition of point 4 of the inclusion criteria
