Annular pancreas (AP) is a rare cause of congenital duodenal obstruction that is usually discovered at the neonatal period, but clinical severities can vary over a wide range and definite diagnosis could be delayed until late childhood or adulthood. We report here a case of AP detected in an 11-year-old girl who had a long history of symptoms of partial duodenal obstruction. Upper gastrointestinal (UGI) study revealed narrowed second portion of duodenum by extrinsic compression, and computed tomography demonstrated complete ring of pancreatic tissue surrounding the second portion of the duodenum. Diamond-shaped duodenoduodenostomy successfully cured the patient, and the postoperative UGI study showed smooth passage through the bypass segment. Although rare, AP should be differentiated in children with unresolved symptoms of partial duodenal obstruction.
环状胰腺（AP）是先天性十二指肠梗阻的罕见病因，通常在新生儿期被发现，但临床严重程度差异很大，确切诊断可能会延迟到儿童晚期或成年期。我们在此报告一例11岁女孩中检测到的环状胰腺病例，该女孩有长期的部分十二指肠梗阻症状史。上消化道（UGI）造影显示十二指肠第二部因外部压迫变窄，计算机断层扫描显示胰腺组织完全环绕十二指肠第二部。菱形十二指肠十二指肠吻合术成功治愈了该患者，术后上消化道造影显示通过旁路段的通道顺畅。尽管罕见，但对于有未缓解的部分十二指肠梗阻症状的儿童，应鉴别环状胰腺。
