Annular pancreas is a rare congenital malformation of the gut; frequently it becomes manifest in adult life. The clinical picture and radiological appearances are dominated by stenosis of the duodenum. The only method for diagnosing annular pancreas up to the present was the barium meal. Its diagnostic accuracy, however, is limited. A knowledge of the characteristic radiological appearances is helpful unless other abnormalities confuse the interpretation. E.R.C.P. is an important advance in diagnosis. The diagnosis of annular pancreas can be made by demonstrating an accessory duct system. The literature is reviewed.
环状胰腺是一种罕见的肠道先天性畸形；它常常在成年期出现症状。临床症状和放射学表现主要为十二指肠狭窄。到目前为止，诊断环状胰腺的唯一方法是钡餐检查。然而，其诊断准确性有限。了解其特征性放射学表现会有所帮助，除非其他异常表现干扰了诊断。内镜逆行胰胆管造影（ERCP）是诊断方面的一项重要进展。通过显示副胰管系统可诊断环状胰腺。本文对相关文献进行了综述。
