Abstract

OBJECTIVES

To describe visualization of gastrointestinal neural ganglia by endoscopic ultrasound (EUS).

METHODS

We retrospectively identified patients in whom neural ganglia were visualized during EUS and the diagnosis of ganglion confirmed by EUS guided fine needle aspiration (FNA) cytology.

RESULTS

Ten patients were identified. Celiac ganglia were visualized in nine, and a perirectal ganglion was visualized in one. Ganglia appeared as discrete hypoechoic structures, often with associated hypoechoic threads that may represent neural rami. Aspiration of ganglia yielded scant material and caused transient pain. Ganglia were best visualized with linear array echoendoscopes. Celiac ganglia (but not the perirectal ganglion) were retrospectively identified on computed tomography scans.

CONCLUSIONS

Gastrointestinal neural ganglia can be imaged by EUS and their identity confirmed by EUS FNA.

摘要

目的

描述通过内镜超声（EUS）对胃肠道神经节的可视化。

方法

我们回顾性地确定了在EUS检查期间神经节被可视化且通过EUS引导下细针穿刺（FNA）细胞学确诊为神经节的患者。

结果

共确定了10例患者。9例患者的腹腔神经节被可视化，1例患者的直肠周围神经节被可视化。神经节表现为离散的低回声结构，通常伴有可能代表神经分支的低回声线。对神经节进行穿刺仅获得少量物质，并引起短暂疼痛。使用线性阵列超声内镜能最佳地可视化神经节。在计算机断层扫描中可回顾性识别出腹腔神经节（但不是直肠周围神经节）。
