P-L11 Comparison of clinical efficacy between LAPS and ALPPS in the Treatment of Hepatitis B Virus-related Hepatocellular Carcinoma. (16th December 2021) - Chen, Zebin
Abstract: Background: The aim of the study is to compare the safety and efficacy of modified ALPPS (laparoscopic microwave ablation and portal vein ligation for staged hepatectomy, LAPS) and classical associating liver partition and portal vein ligation for staged hepatectomy (ALPPS) in the treatment of hepatitis B virus (HBV)-related hepatocellular carcinoma (HCC). Methods: Clinical data of patients with HBV-related HCC who underwent LAPS or ALPPS surgery in our institute from April 2013 to October 2020 were retrospectively analyzed. Results: 31 patients with HBV-related HCC were retrospectively collected in this study (LAPS = 8, ALPPS = 23). 7 patients with LAPS and 19 patients with ALPPS proceeded to resection (resection rate: 87.5% vs. 82.6%, P > 0.05). The hypertrophy rate of future liver remnant (FLR) caused by ALPPS was higher than that of LAPS (24.3 vs. 11.7 mL/d, P = 0.024). Compared with the ALPPS, LAPS was associated with less blood loss (300ml vs. 40ml, P < 0.001) during stage 1, lower comprehensive complication index (CCI) after stage 1 (8.7 vs. 0, P = 0.023) and lower total CCI (20.9 vs 0, P = 0.018) for two stages. Two years' recurrence-free survival rate and over survival rate for ALPPS and LAPS were 17.3%, 34.3% (P = 0.105), and 28.9%, 100.0% (P = 0.011) respectively. Conclusions: Compared with ALPPS, LAPS can reduce the occurrence of complications in patients with HBV-related HCC and improve patients' prognoses.
