Background: In case of bilobar colorectal liver metastases (CLM)associating liver partition and portal vein ligation for staged hepatectomy (ALPPS)has been proposed. Enhanced one-stage ultrasound-guided hepatectomy (e-OSH)may represent a further solution for these patients. Aim of this study was to compare by case-match analyses the outcome of ALPPS and e-OSH. Methods: Between 2012 and 2017, patients undergoing ALPPS for bilobar CLM were matched 1:2 with patients receiving e-OSH. Patients were matched according to the Fong Score (1–3/4–5), the number of CLM (3–7/≥8), the number of CLM in the left liver (1–2/≥3)and preoperative chemotherapy. All the patients in the e-OSH group had a right -sided major vascular contact. The main endpoints of the study were perioperative outcomes, overall (OS)and disease-free survival (DFS). Results: Seventy-eight patients were selected (26 ALPPS and 52 e-OSH)based on matching process. The two treatments differed significantly in major morbidity (26.9% ALPPS vs 7.7% e-OSH, p = 0.017). Median OS (31.7 vs 32.6 months)and DFS (10.6 vs 7.8 months)were comparable between the two groups. Conclusions: This study demonstrates that ALPPS and e-OSH for bilobar CLM achieve comparable long-term results, despite higher morbidity reported after ALPPS. These findings should drive to reposition e-OSH in managing these patients.

Abstract

Background: In case of bilobar colorectal liver metastases (CLM)associating liver partition and portal vein ligation for staged hepatectomy (ALPPS)has been proposed. Enhanced one-stage ultrasound-guided hepatectomy (e-OSH)may represent a further solution for these patients. Aim of this study was to compare by case-match analyses the outcome of ALPPS and e-OSH. Methods: Between 2012 and 2017, patients undergoing ALPPS for bilobar CLM were matched 1:2 with patients receiving e-OSH. Patients were matched according to the Fong Score (1–3/4–5), the number of CLM (3–7/≥8), the number of CLM in the left liver (1–2/≥3)and preoperative chemotherapy. All the patients in the e-OSH group had a right -sided major vascular contact. The main endpoints of the study were perioperative outcomes, overall (OS)and disease-free survival (DFS). Results: Seventy-eight patients were selected (26 ALPPS and 52 e-OSH)based on matching process. The two treatments differed significantly in major morbidity (26.9% ALPPS vs 7.7% e-OSH, p = 0.017). Median OS (31.7 vs 32.6 months)and DFS (10.6 vs 7.8 months)were comparable between the two groups. Conclusions: This study demonstrates that ALPPS and e-OSH for bilobar CLM achieve comparable long-term results, despite higher morbidity reported after ALPPS. These findings should drive to reposition e-OSH in managing these patients.
