摘要
目的评价超声内镜在异位胰腺诊治中的价值。方法回顾分析该院2003年1月～2009年1月诊治的43例上消化道异位胰腺患者的内镜下表现及超声内镜(EUS)影像特征,记录病变的部位、大小、生长方式、来源层次、回声特征及治疗情况。结果异位胰腺好发于胃窦,尤其大弯侧,内镜下主要表现为黏膜隆起中央见脐样凹陷;EUS下呈多样性,有高、低或混杂回声,可发生于管壁任何一层或几层。其主要特点为黏膜下层偏低或网格样混杂回声,内部回声不均匀,部分内部出现特征性管状结构样回声,边界大多清晰。病理确诊异位胰腺10例(其中9例行EUS检查),7例的EUS结果与病理一致(78%)。结论超声内镜提供了更准确的诊断异位胰腺的途径,可指导选择相应的治疗措施。
[ Objective ] To evaluate the value of endoscopic ultrasonography （EUS） in the diagnosis and treatment of heterotopic pancreas by means of retrospective analysis of their endoscopic and EUS features. [ Methods ] Totally 207 cases with upper gastrointestinal protrusive lesions were examined by using endoscope and EUS from January 2003 to January 2009. And the location, size, growth pattern of the lesions, layer of origin, internal echo pattern and therapy were recorded. The EUS images of heterotopie pancreas in 43 cases were reviewed. [ Results ] Heterotopie pancreas was usually found in gastric antrum, especially in greater curvature. Most of them were found by EUS to have umbilicate pits with opening on the top of the lesions which had different echoes such as hypoecho, hypereeho or mixed echo, and were located in one or more gastrointestinal layers with clear boundary. Most of them originated from submucosa with hypoecho or mixed echo, some were characterized by tube-like echo in the center of the lesions. In 10 cases confirmed by pathologic data, 9 cases were followed by EUS, the coincidence of EUS and pathologic diagnosis was 78% （7/9）. [ Conclusion] EUS is an useful technique for diagnosing heterotopic pancreas and guiding the corresponding treatment. Because most of them are benign, they need not treatment but follow-up by endoscopy if no evident symptoms appear.
