Objective:To analyze the X-ray barium gastrointestinal imaging characters of the descending duodenal diverticulum, and discuss its diagnostic values. Method: 114 patients with descending duodenal diverticulum admitted to our hospital from January 2011 to October 2013 and diagnosed by X-ray barium gastrointestinal imaging were selected by retrospective analysis. The number, size and complications of diver-ticulum were recorded respectively, and the gastrointestinal imaging characters of the descending duodenal diverticulum were analyzed. All patients were followed up for one year and short-term prognosis was ob-tained. Result:82 patients had solitary descending duodenal diverticulum and the size of diverticulum was from 1.0cm×1.0cm to 3.0cm×3.0cm. The bigger diverticulums resulted in empty delay or incomplete empty. The gastrointestinal complications in the 1. 0cm × 1. 0cm to 3. 0cm × 3. 0cm group or narrow neck group were higher than those in other groups ( P<0.05) . In addition, the patients with biggerdiverticulum and/or narrow neck had poor short-term prognosis. Conclusion:The examination rate of X-ray barium gastrointestinal ima-ging is high to detect the descending duodenal diverticulum, which is a simple, safe and reliable diagnostic method.%目的:分析十二指肠降部憩室的消化道X 线钡餐造影的特点,并探讨其诊断价值. 方法:采用回顾性分析方法,选择2011年1月至2013年10月行消化道X线钡餐造影确诊为十二指肠憩室患者114例,观察憩室个数、大小、形态及并发症,总结分析其影像学特点. 对所有患者1年随访,探讨憩室与预后关系. 结果:十二指肠降部憩室中单发憩室82 例( 71. 93%) ,大小在2. 0cm × 2. 0cm~3. 0cm×3.0cm之间,憩室越大排空延迟或不能完全排空. 憩室直径≥3.0cm×3.0cm及颈窄时消化道症状出现率明显高于其他各组( P<0.05) ,并且较大憩室伴/不伴颈窄患者近期预后差. 结论:消化道X线钡餐造影检查十二指肠降部憩室的检出率较高,是一种简单、安全、可靠的诊断方法.
