摘要

目的：内镜超声引导下组织采集（EUS-TA）作为经皮活检的替代方法，在肝脏病灶的治疗方面已受到广泛关注。尽管有报道称 EUS-TA 治疗肝脏局灶性病变的效果良好，但还没有研究关注小的肝脏局灶性病变（≤2 厘米）。本研究旨在评估 EUS-TA 治疗肝脏小病灶（≤2 厘米）的效果：方法：回顾性研究了2016年至2022年期间为肝脏局灶性病变实施的EUS-TA的详细情况。方法：回顾性研究了2016年至2022年期间为肝脏局灶性病变实施的EUS-TA的详细情况，比较了≤2厘米病变和>2厘米病变病例的结果。主要结果为诊断能力和不良事件：结果：对109例肝局灶病变进行了EUS-TA检查。109例病例中，32例（29.3%）病变≤2厘米，77例（70.6%）病变>2厘米。≤2厘米组的右叶病变和经十二指肠穿刺明显较少。两组之间在针规、针型和穿刺次数上没有明显差异。≤2厘米组的灵敏度、特异性和准确率分别为96.8%、100%和96.8%，>2厘米组分别为97.4%、100%和97.4%，组间无明显差异。各组之间的不良反应无差异（≤2厘米组为0%，＞2厘米组为2.3%）：结论：EUS-TA治疗≤2厘米的肝脏小病灶效果良好，与治疗＞2厘米的病灶效果相似。

The outcomes of endoscopic ultrasound-guided tissue acquisition for small focal liver lesions measuring ≤2 cm

Objectives

Endoscopic ultrasound-guided tissue acquisition (EUS-TA) for focal liver lesions has gained attention as an alternative to percutaneous biopsy. Although the outcomes of EUS-TA for focal liver lesions have been reported to be favorable, no studies have focused on small focal liver lesions (≤2 cm). The aim of this study was to evaluate the outcomes of EUS-TA for small focal liver lesions (≤2 cm).

Methods

The details of EUS-TA performed for focal liver lesions between 2016 and 2022 were retrospectively reviewed. The outcomes were compared between cases involving ≤2 cm lesions and those involving >2 cm lesions. The primary outcomes were diagnostic ability and adverse events.

Results

EUS-TA for focal liver lesions was performed in 109 cases. Of the 109 cases, 32 (29.3%) involved ≤2 cm lesions and 77 (70.6%) involved >2 cm lesions. Right lobe lesions and transduodenal puncture were significantly fewer in the ≤2 cm group. There were no significant differences in needle gauge, needle type, or number of punctures between the groups. The sensitivity, specificity, and accuracy rates were 96.8%, 100%, and 96.8%, respectively, in the ≤2 cm group and 97.4%, 100%, and 97.4%, respectively, in the >2 cm group, with no significant differences between the groups. There was no difference in adverse events between the groups (0% in the ≤2 cm group and 2.3% in the >2 cm group).
