ObjectiveTo evaluate whether radiofrequency-assisted associating liver partition and portal vein ligation for staged hepatectomy (RALPPS) is a safer and more effective modified treatment for patients with cirrhosis-related hepatocellular carcinoma (HCC). MethodsRALPPS were performed in patients with HCC and insufficient volume of future liver remnant (FLR<40%). Data of the patients during perioperative period such as operative morbidity, mortality, operative time, blood loss, percent increase in FLR, and interval between operations, were analyzed to assess the effectiveness and safety of the operation. ResultsA total of 8 patients were performed the RALPPS operation, and 6 cases completed both stages, 2 cases of postoperative complications or tumor metastasis did not complete the two phase of surgery. The average first and second stages operative time was (214.3±35.7) min, (266.7±46.0) min, respectively, and the average two stages blood loss during the operation was (218.8±113.2) mL,(501.7±224.5) mL, respectively. The mean preoperative FLR was (26.4±7.1)%, and the mean FLR before the second stage was (46.2±4.6)%. The average percentage increase in FLR during the interval time was 35%-113%, and the mean time interval between operations were (22.2±6.4) days. One case died of renal failure and severe pulmonary infection after two operation. Seven patients were followed-up (11.6+2.0) months (8-15 months). Two patients who had not completed the two-stage operation died within 3 months after discharge. Three patients who had completed the two-stage operation were tumor recurrence in 3-9 months after discharged from hospital and supplemented interventional therapy, 1 of them died,and 2 patients were followed-up to now without recurrence. ConclusionsRALPPS is equivalent to ALPPS for treating patients with cirrhosis-related HCC and insufficient FLR volume.
