摘要/Abstract

摘要：

环状胰腺是一种相对罕见的先天性发育异常，影像学表现无特异性，所以有误诊的可能。本文报道1例术前误诊为壶腹部肿瘤的环状胰腺合并十二指肠球部狭窄致上消化道梗阻病例，经手术探查后确诊。通过回顾诊疗过程及文献复习，进一步探讨内镜下胰胆管造影术（ERCP）在该类疾病治疗中的潜在应用价值。

Abstract:

Annular pancreas is a rare congenital anomaly that is frequently misdiagnosed due to its nonspecific imaging characteristics. This article presented a case of annular pancreas with duodenal bulb stenosis causing upper gastrointestinal obstruction, which was initially misdiagnosed as ampullary tumor preoperatively and subsequently confirmed by surgical exploration. Through retrospective case analysis and literature review, we aimed to evaluate the potential clinical value of endoscopic retrograde cholangiopancreatography (ERCP) in the management of this condition.

Key words: Annular pancreas, Ampullary tumor, Pancreaticoduodenectomy
