Pancreatic ectopia (PE) consists in the existence of pancreatic tissue outside its usual location in the normal pancreas. This rare condition, with an uncertain incidence, occurs most often in the stomach, duodenum and jejunum. The ectopic pancreas is usually asymptomatic but it may become clinically significant when it becomes affected with the same kind of complications which affect the normal pancreas - inflammation, bleeding, obstruction of the anatomic structure where it is located and malignant transformation. As the most common site of this kind of lesion is the submucosa, endoscopic ultrasonography is the most useful exam in its characterization; the final diagnosis is, however, histological. Surgical resection is indicated in symptomatic cases and when there is malignant transformation of the lesion. In this article the author presents a clinical case of gastric PE and makes a theoretical review about this entity, its etiopathogenesis, semiology, method of diagnosis and therapy, noting the indications and surgical options to treat this rare condition.
胰腺异位（PE）是指胰腺组织存在于正常胰腺的正常位置以外。这种罕见病症的发病率尚不确定，最常发生于胃、十二指肠和空肠。异位胰腺通常无症状，但当它出现与影响正常胰腺相同类型的并发症时，可能具有临床意义，这些并发症包括炎症、出血、其所在解剖结构的梗阻以及恶变。由于这类病变最常见的部位是黏膜下层，内镜超声检查是对其进行特征描述最有用的检查；然而，最终诊断仍需依靠组织学检查。有症状的病例以及病变发生恶变时，均需进行手术切除。在本文中，作者呈现了一例胃PE的临床病例，并对该病症、其病因病机、症状学、诊断方法和治疗进行了理论综述，同时指出了治疗这种罕见病症的适应证和手术选择。
