Abstract:Objective To evaluate the efficacy and safety of modified ALPPS procedure. Methods Patients who were performed ALPPS in Chinese PLA Air Force Medical Center and Zibo Central Hospital 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 month (±4.5month). Conclusion 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.
