X线钡餐造影十二指肠降部憩室的消化道诊断特点分析

The X- ray Barium Gastrointestinal Imaging Characters of the Descending Duodenal Diverticulum

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。

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 diverticulum 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 obtained. 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 imaging is high to detect the descending duodenal diverticulum,which is a simple,safe and reliable diagnostic method.
