Clinical evaluation of modified ALPPS procedures based on risk-reduced strategy for staged hepatectomy.

INTRODUCTION AND

OBJECTIVES

Radical resection remains the only curative treatment for liver tumors. Although associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) can increase the resection rate, huge controversy exists for high reported mortality and morbidity. This study was to evaluate the efficacy and safety of modified ALPPS procedure.

PATIENTS AND

METHODS

Patients who were performed ALPPS in single-center in recent 5 years were retrospectively reviewed. The modified strategy included strict patient selection, precise future liver remnant (FLR) assessment and operation planning, and usage of minimally invasive methods. Data including clinical records, functional FLR increase, complications, and overall survival (OS) were analyzed.

RESULTS

Sixty patients underwent modified ALPPS procedure and recovered well. No severe complications happened after the 1-stage operation, and the increasing FLR was 179.3 cm3(±72.4 cm3), with similar functional FLR increase. The OS was 20.0 months (±4.5month).

CONCLUSIONS

ALPPS could be a feasible treatment for complex liver tumors by risk-reduced modification. It could be expected to provide long-term survival for patients without enough FLR.
