成人非梗阻性巨十二指肠症1例病例报告和文献复习

A case report and literature review of adult non-obstructive megaduodenum disease

巨十二指肠是一种以十二指肠显著扩张为特征的疾病,临床较为少见。其病因可分为梗阻性和非梗阻性。本文报道了1例在南京市第一医院河西院区首次确诊的巨十二指肠症患者。入院后完善胃肠镜,CT小肠造影,肠系膜上动脉CT血管造影检查,排除其他梗阻因素后诊断为先天性非梗阻性巨十二指肠症。先天性巨十二指肠大多在婴幼儿时期确诊,且需要手术治疗。成人先天性巨十二指肠极为罕见,需与其他梗阻性病因鉴别。本病例提供了该病的胃肠镜图像及影像学检查资料,为本病的确诊提供思路。

Macroduodenum is a disease characterized by significant dilation of the duodenum,relatively rare in clinic.Its etiology can be divided into obstructive and non-obstructive.This paper reports a case of megaduodenum disease diagnosed for the first time in Hexi Hospital,Nanjing First Hospital Affiliated to Nanjing Medical University.After admission,gastroenteroscopy,CT enterography,and CT angiography of superior mesenteric artery were performed.After excluding other obstructive factors,congenital non-obstructive megaduodenum disease was diagnosed.Congenital megaduodenum is most often diagnosed in infancy and requires surgical treatment.Congenital megaduodenum in adults is extremely rare and needs to be distinguished from other obstructive causes.This case provides the gastroenteroscopy image and imaging data of the disease,providing ideas for the diagnosis of the disease.
