275例成人十二指肠壅积症分析

A Diagnostic Analysis of Duodenal Stasis in 275 Adult Patients

目的 :探讨成人十二指肠壅积症的病因、病变部位及各种诊断方法的效果。方法 :应用钡餐、低张性十二指肠造影、B超或CT等单项或多项诊断方法 ,对 2 75例成人十二指肠壅积症进行定位和定性诊断 ,并比较各种诊断方法的效果。结果 :12 4例肠系膜上动脉综合征经钡餐定位 ,与定性诊断符合率分别达 94.3%与 5 4.0 % ,结合低张性十二指肠造影 ,则分别提高至 97.5 %与 87.0 % ;15 1例其他患者经钡餐定位 ,与定性诊断符合率分别为 81.4%与 2 1.1% ,结合低张性十二指肠造影、B超或CT ,则分别可达 94.0 %与 6 9.5 %。结论 :肠系膜上动脉综合征经钡餐检查大多可作出定位诊断 ,结合低张性十二指肠造影可明显提高定性诊断符合率 ;其他患者经钡餐检查效果较差 ,结合低张性十二指肠造影、B超或CT ,可明显提高定位与定性诊断的符合率。

Objective:To investigate the causes and loci of adult duodenal stasis and compare the efficiency of different diagnoses in it.Methods:275 adults with duodenal stasis were examined by single or multiple ways such as barium study,hypotonic duodenography,ultrasound (US) or CT.Results:By barium study,correct rates of niveau and etiological diagnoses in 124 adults with superior mesenteric artery syndrome were 94.3% and 54.0% respectively;combined with hypotonic duodenography,their rates were raised to 97.5% and 87.0% respectively.By barium study,correct rates of niveau and etiological diagnoses in 151 adults with other causes were 81.4% and 21.1% respectively;combined with hypotonic duodenography,US or CT, their rates were raised to 94.0% and 69.5% respectively.Conclusions:Niveau diagnosis in the majority of adults with superior mesenteric artery syndrome can be made by barium study;correct rate of etiological diagnosis in them can be raised obviously combined with hypotonic duodenography.By barium study,diagnostic efficiency in adults with other causes was lower.Combined with hypotonic duodenography,US or CT,correct rates of niveau and etiological diagnoses in them may be raised remarkably.
