Heterotopic pancreas (HP) is a relatively uncommon entity that is defined as pancreatic tissue without a true anatomical or vascular connection to the pancreas. HP does not cause symptoms in most cases but can occasionally produce various manifestations, including nausea, vomiting, abdominal pain, and even heterotopic pancreatitis. Here, we report an unusual case in which heterotopic pancreatitis complicated by the formation of a pseudocyst that caused gastric outlet obstruction was diagnosed based on serum hyperamylasemia and findings from endoscopic ultrasonography (EUS)-guided fine needle aspiration (EUS-FNA) cytology. EUS-guided single pigtail stent insertion was successfully performed for recurrent gastric outlet obstruction. The patient has remained healthy and symptom-free during 4 years of surveillance. In the context of the relevant literature, the described case is a rare case of HP complicated by a pseudocyst treated EUS-FNA and stent insertion.
异位胰腺（HP）是一种相对少见的实体，其定义为与胰腺无真正解剖或血管连接的胰腺组织。在大多数情况下，HP 不会引起症状，但偶尔会出现各种表现，包括恶心、呕吐、腹痛，甚至异位胰腺炎。在这里，我们报告了一个不寻常的病例，在该病例中，异位胰腺炎合并假性囊肿形成导致胃出口梗阻，根据血清淀粉酶升高和内镜超声引导下细针抽吸（EUS-FNA）细胞学检查结果诊断。EUS 引导下的单猪尾支架置入术成功用于复发性胃出口梗阻。在 4 年的监测期间，患者保持健康，无症状。在相关文献的背景下，所描述的病例是一例罕见的 HP 合并假性囊肿，经 EUS-FNA 和支架置入治疗。
