BACKGROUND/AIMS: Non-invasive tissue sampling from the lower intra-abdominal and pelvic cavity is challenging. The role of endoscopic ultrasound-guided fine-needle aspiration (EUS-FNA) in this situation is not well-established because of the limitations of the curved linear-array echoendoscopy-EUS for colonic insertion. The aim of this study was to report our institutional experience of transcolonic EUS-FNA using forward-viewing therapeutic linear echoendoscopy-EUS (FV-EUS) in combination with fluoroscopic guidance.
Medical records of 13 patients who underwent transcolonic EUS-FNA of extracolonic lesions using FV-EUS in combination with fluoroscopic guidance at Aichi Cancer Center Hospital, Nagoya, Japan from June 2015 to November 2018 were retrospectively reviewed.
Using FV-EUS under fluoroscopic guidance, the FNA procedure could be performed successfully in all patients (100% technical success), with a median procedure time of 31 minutes. The sensitivity, specificity, and accuracy of EUS-FNA for detecting malignant lesions in this study were 91%, 100%, and 92%, respectively. There were no adverse events associated with the EUS-FNA procedure.
FV-EUS in combination with fluoroscopic guidance is an easy, safe, and effective technique for FNA of extracolonic lesions in the lower abdomen.
背景/目的：从腹腔下部和盆腔进行非侵入性组织采样具有挑战性。由于用于结肠插入的弯曲线阵超声内镜（EUS）存在局限性，内镜超声引导下细针穿刺抽吸术（EUS-FNA）在这种情况下的作用尚未完全确立。本研究的目的是报告我们机构使用前视治疗性线性超声内镜（FV-EUS）联合荧光透视引导进行经结肠EUS-FNA的经验。
回顾性分析2015年6月至2018年11月在日本名古屋爱知癌症中心医院接受FV-EUS联合荧光透视引导对结肠外病变进行经结肠EUS-FNA的13例患者的病历。
在荧光透视引导下使用FV-EUS，所有患者均成功完成FNA操作（技术成功率100%），中位操作时间为31分钟。本研究中EUS-FNA检测恶性病变的敏感性、特异性和准确性分别为91%、100%和92%。EUS-FNA操作未发生不良事件。
FV-EUS联合荧光透视引导是一种用于下腹结肠外病变FNA的简便、安全且有效的技术。
