【摘 要】目的：探讨小探头超声内镜检查胃异位胰腺等特点，分析其诊断价值。方法：总结35例经小探头超声内镜诊断并有病理及免疫组化证实的胃异位胰腺的病例资料。记录胃异位胰腺的部位、病变层次、回声特征及治疗情况，总结其内镜及超声图像特征。结果：胃异位胰腺病例中病变部位最多见于胃窦，其次位于胃体。多数累及粘膜下层及固有肌层，部分仅累及粘膜下层。超声内镜下异位胰腺呈高回声、稍高回声及不均质回声团块，所有病例均行手术切除后送病理及免疫组化检查，明确诊断为异位胰腺。结论：超声小探头检查能辅助诊断胃异位胰腺，并对指导胃异位胰腺治疗具有重要的意义。

    [Abstract] Objective：To explore the value of endoscopic ultrasonography (EUS)mini probes in diagnosing Heterotopic pancreas Methods A retrospective analysis and a summary were made to the endosonographic features of 35 cases of Heterotopic pancreas confirmed by pathological study or immunohistochemical study.Results The most frequent localizations of Heterotopic pancreas were at antral and body.Endoscopic ultrasonographic characteristics of Heterotopic pancreas most revealed hyperechoic and internal echoic images located in submucosal lesions and muscularis propria.All the cases were confirmed by pathological study or immunohistochemical study.Conclusions EUS mini probes can provide auxiliary diagnosis and it is of certain reference value in assisting treatment of Heterotopic pancreas. ......
