Celiac ganglia (CG) can be seen by endoscopic ultrasound; they play an important role in pain management and are a potential site for extrapancreatic tumor neural invasion.
To evaluate the frequency of CG visualization during endoscopic ultrasound examination and to evaluate the feasibility of this technique to identify extrapancreatic tumor neural invasion in patients with pancreatic lesions.
We retrospectively reviewed all endoscopic ultrasound studies performed between November 2007 and June 2010. Images of the celiac region were presented to an endosonographer, who reported the presence or absence of CG.
We included 31 cases. CG were identified in 14 (45%) cases. Average size was 10mm (range 4-25mm) by±1mm (range 1-7mm). In 2 cases, fine needle aspiration biopsy was performed and reported nerve cell bodies; in one case malignant cells were seen.
CG were identified in 45% of the cases. Fine needle aspiration biopsy can detect unanticipated extrapancreatic tumor neural invasion in pancreatic malignancies.
腹腔神经节（CG）可通过内镜超声观察到；它们在疼痛管理中发挥重要作用，并且是胰腺外肿瘤神经侵犯的潜在部位。
评估内镜超声检查期间CG可视化的频率，并评估该技术识别胰腺病变患者胰腺外肿瘤神经侵犯的可行性。
我们回顾性分析了2007年11月至2010年6月期间进行的所有内镜超声检查。将腹腔区域的图像呈现给一位内镜超声医师，由其报告CG的有无。
我们纳入了31例病例。14例（45%）病例中识别出了CG。平均大小为10mm（范围4 - 25mm），直径±1mm（范围1 - 7mm）。2例进行了细针穿刺活检，报告有神经细胞体；1例可见恶性细胞。
45%的病例中识别出了CG。细针穿刺活检可检测出胰腺恶性肿瘤中意外的胰腺外肿瘤神经侵犯。
