藏族内镜下十二指肠球部解剖结构的变异分析

目的　了解汉族、藏族不同民族间球部解剖结构变异及球部溃疡的发生率有无差异。方法　内镜观察 2 2 4 74例汉族和 1 987例藏族的球部解剖结构及球部溃疡发生情况。结果　藏族十二指肠球部解剖结构变异率 2 7.83%,明显高于汉族 1 6.2 3%(P <0 .0 1 ) ,球部溃疡检出率5 .69%,明显低于汉族 1 5 .76%(P <0 .0 0 1 )。结论　藏族十二指肠球部解剖结构变异率明显高于汉族 ,藏族球部溃疡检出率明显低于汉族。

THE ANATOMICAL MUTATION AT BALL-PORTION OF DUODENUM IN TIBETAN

Objective To investigete the difference of anatomic structure and the morbidity rate of ulcer at ball-portion of duodenum between Hans and Tibetans.Methods The anatomic structure of duodenum of 22474 Hans and 1987 Tibetans was observed under endoscope.Results The anatomic mutation rate at ball-portion of duodenum in Tibetans was 27.83%,higher than that in Hans obviously(16.23%,P<0.001).but ulcer morbidity rate at duodenum in Tibetans was 5.69%,lower than that in Hans significantly(15.76%,P<0.001).Conclusion The anatomic mutation rate at ball-portion of duodenum in Tibetans was higher than that in Hans obviously,but ulcer morbidity rate at duodenum in Tibetans was lower than that in Hans significantly.
