胃角处异位胰腺误诊为胃间质瘤的诊断与治疗

Diagnosis and treatment of heterotopic pancreas at the angular notch of stomach misdiagnosed as gastric stromal tumor

异位胰腺是指在胰腺以外部位生长，与正常胰腺组织无解剖和血管联系的孤立胰腺组织，属于先天性异常，是临床少见疾病。因其临床表现容易与其他消化道疾病相混淆，常规内镜检查不能为术前诊断提供可靠的依据，极易误诊为其他消化道疾病，导致确诊困难，从而造成不恰当的治疗。因此，鉴别异位胰腺和其他消化道疾病非常重要。2014年3月承德医学院附属医院收治1例胃部异位胰腺患者，探讨该类疾病的临床特点、鉴别诊断及治疗方法。

Heterotopic pancreas is usually defined as a presence of pancreatic tissue without any anatomical or vascular continuity, and is one of the congenital and rare diseases. The clinical manifestations are easily confused with other gastrointes- tinal diseases, and conventional endoscopic examination cannot provide a clear preoperative diagnosis, therefore heterotopic pan- creas is often misdiagnosed. It is very important to distinguish heterotopie pancreas and other digestive diseases. In this article, the clinical characteristics, differential diagnosis and treatment method of one patient with heterotopic pancreas who was admitted to the Affiliated Hospital of Chengde Medical College in March 2014 were analyzed.
