Ultrasound endoscopes with mechanical sector forward scan transducers make it possible to perform FNA under EUS, and drainage by tracing the needle in the ultrasound pictures by using the same monitor unit as for radial scan ultrasound endoscopes for EUS diagnosis. It is important to diagnose the lesions from the histological findings; however, there remain some problems about false negatives, histological diagnosis from very tiny materials, and the risk of disseminating the malignant cells by the procedure.
带有机械扇形前向扫描换能器的超声内镜使得在超声内镜引导下进行细针穿刺抽吸（FNA）成为可能，并且通过使用与用于超声内镜诊断的径向扫描超声内镜相同的监测单元，在超声图像中追踪针来进行引流。从组织学结果诊断病变很重要；然而，在假阴性、从非常微小的材料进行组织学诊断以及该操作导致恶性细胞播散的风险方面仍然存在一些问题。
