[摘 要] 目的:总结胆道闭锁(biliary atresia,BA)Kasai 术(Kasai procedure,KP)后自体肝生存(native liver survival,NLS)状
况,分析KP后早期死亡或者需肝移植(death or liver transplantation,D/LT)的相关因素。方法:收集2020年5月—2024年5月在
南京医科大学附属儿童医院接受KP的Ⅲ型BA患儿临床资料,Kaplan⁃Meier生存分析法总结术后1年NLS特点,通过单因素和
多因素Cox回归模型分析寻找KP后早期D/LT的相关因素。结果:共105例接受KP的BA患儿纳入研究,随访期12~60个月,
中位随访时间34个月,41例D/LT,其中术后第1年内D/LT 35例,占总D/LT人数的85.4%。Kaplan⁃Meier生存曲线估计KP后平
均NLS时间为(38.4±2.5)个月,1年实际NLS率为66.7%,2年估计自体肝累积生存率为59.6%,估计3~5年内累积生存率与2年
累积生存率一致。单因素和多因素Cox 回归模型发现术前超声肝脏硬度(liver stiffness measurement,LSM)和术后3个月内未
能达到黄疸清除(jaundice clearance,JC)是KP术后D/LT的独立相关因素[HR(95%CI):1.031(1.001~1.064),P=0.049;HR(95%
CI):6.394(3.141~13.015),P < 0.001]。66例(62.9%)术后3个月内发生胆管炎,其中18例(27.27%)发生在术后1个月内,术后
1个月内发生胆管炎的患儿术后3个月JC率低于术后1个月后发生胆管炎的患儿(50.0% vs. 77.1%,χ =4.546,P=0.033)。结论:
2
KP后D/LT多发生在术后1年内,术后2年可达到NLS稳定状态。术前超声LSM及术后JC时间是术后早期D/LT的独立相关因
素,术前LSM高于11.6 kPa、Metavir预分级F2以上、JC时间>3个月,NLS率明显降低。KP后1个月内发生胆管炎会降低KP术
后3个月的JC率。

[Abstract] Objective:To summarize the status of native liver survival(NLS)in the early stage after Kasai procedure(KP)in patients
with biliary atresia(BA),and to analyze the factors associated with early death or liver transplantation(D/LT)after KP. Methods:The
clinical data of children with type Ⅲ BA who underwent KP at the Affiliated Children’s Hospital of Nanjing Medical University from
May 2020 to May 2024 were collected. The Kaplan⁃Meier survival analysis was used to summarize the characteristics of NLS after KP
at 1 year postoperatively. Univariate and multivariate Cox regression models were employed to identify associated factors for early D/LT
after KP. Results:A total of 105 children with BA who underwent KP were enrolled in the study,with a follow⁃up period of 12 to 60
months and a median follow⁃up time of 34 months. Among them,41 cases experienced D/LT,including 35 cases of D/LT within the first
year after surgery,accounting for 85.4% of the total D/LT cases. The Kaplan⁃Meier survival curve estimated an average NLS time of
(38.4±2.5)months after KP,with an actual 1⁃year NLS rate of 66.7% and an estimated 2⁃year cumulative NLS rate of 59.6%. The
estimated 3⁃5 year cumulative survival rate was consistent with the 2⁃year cumulative survival rate. Univariate and multivariate Cox
regression models revealed that the preoperative liver stiffness measurement(LSM)by ultrasonography and a jaundice clearance(JC)
time exceeding 3 months postoperatively are two independent associated factors with early D/LT after the KP[HR(95%CI):1.031
