摘要
背景和目的：比较内镜下超声引导下肝活检（EUS-LB）和经皮超声引导下肝活检（PC-LB）在组织充分性、组织学产量、不良事件和患者满意度方面的数据有限。方法：在这项单中心、平行组、非效性试验中，我们将参与者1:1随机分配到EUS-LB （19 g Franseen-tip活检针；改良的湿肝素吸吸；左和/或右肺叶）或PC-LB （18 g BioPince™全芯针；右肺叶）。主要终点是标本充足性，定义为总标本长度(TSL)≥15 mm，完整门脉束(CPT)≥8。非劣效性评估采用绝对风险差，预先规定的边际为-10%。结果：90名参与者被随机化。在意向治疗分析中，44/45（97.8%）的EUS-LB和29/45（64.4%）的PC-LB组达到了主要终点（风险差异+33.3%;95%CI: +17.9%至+48.1%），符合非劣效性并显示出优势(p结论：EUS-LB在预先指定的充分性终点上不劣于PC-LB，且优于PC-LB，产生更大的标本长度和CPT计数，更常见但主要是轻微的不良事件。试验报名：CTRI/2023/10/058529；NCT06047327。
EUS-guided biopsy using 19-gauge Franseen needle versus percutaneous ultrasound-guided biopsy using 18-gauge full-core cutting needle for parenchymal liver disease: A randomized controlled, non-inferiority trial.
Background and aims: There is limited data comparing endoscopic ultrasound-guided liver biopsy (EUS-LB) with percutaneous ultrasound-guided liver biopsy (PC-LB) regarding tissue adequacy, histologic yield, adverse events, and patient satisfaction.
Methods: In this single-center, parallel-group, non-inferiority trial, we randomized participants 1:1 to EUS-LB (19-G Franseen-tip biopsy needle; modified wet-heparin suction; left and/or right lobe) or PC-LB (18-G BioPince™ full-core needle; right lobe). The primary endpoint was specimen adequacy, defined as total specimen length (TSL) ≥15 mm and complete portal tracts (CPT) ≥8. Non-inferiority was assessed using absolute risk difference with a prespecified margin of -10%.
Results: Ninety participants were randomized. In intention-to-treat analysis, the primary endpoint was achieved in 44/45(97.8%) of EUS-LB and 29/45(64.4%) of PC-LB group (risk difference +33.3%; 95%CI: +17.9% to +48.1%), meeting non-inferiority and demonstrating superiority (p<0.001). With EUS-LB and PC-LB, the median TSL was 6.9cm versus 2.0cm and the median CPT number was 42 versus 9, respectively (both p<0.001). Even a single pass of EUS-LB outperformed PC-LB, with respect to sample adequacy, TSL, total CPT, and biopsy area (all p<0.001). PC-LB specimens were less fragmented (median 1 vs 13; p<0.001) and had greater median width (747.8μm vs. 667.2μm; p<0.001). Adverse events occurred more frequently with EUS-LB (26.7% vs. 4.4%; p=0.007); all but one were minor. Post-procedural pain was minimal, and satisfaction ratings were high in both groups.
Conclusions: EUS-LB was non-inferior and superior to PC-LB for the prespecified adequacy endpoint, yielding substantially greater specimen length and CPT counts, with more frequent but predominantly minor adverse events.
