Annular pancreas is a rare congenital anomaly characterized by the presence of ectopic pancreatic tissue surrounding the descending part of the duodenum. It is one of the few congenital anomalies of the gastrointestinal tract which can produce symptoms late in life. In adults, the factors initiating symptoms are recurrent pancreatitis, duodenal stenosis at the site of the annulus, or duodenal or gastric ulceration. We report a new case involving a 24-year-old woman hospitalised for epigastric pain, nausea and vomiting. Radiological examination was consisted with an annular pancreas. At operation a complete obstruction of the second part of the duodenum was found, caused by an annular pancreas, no other congenital anomaly of the intra-abdominal organs was noted. A gastroenterostomy was performed.
环状胰腺是一种罕见的先天性异常，其特征是十二指肠降部周围存在异位胰腺组织。它是少数几种可在生命后期出现症状的胃肠道先天性异常之一。在成年人中，引发症状的因素包括复发性胰腺炎、环状部位的十二指肠狭窄或十二指肠或胃溃疡。我们报告了一例新病例，患者为一名24岁女性，因上腹部疼痛、恶心和呕吐入院。放射学检查显示为环状胰腺。手术中发现十二指肠第二部完全梗阻，由环状胰腺引起，未发现腹腔内其他器官有先天性异常。遂行胃肠吻合术。
