西藏那曲地区肺结核117例的X线分析(附广东省湛江市肺结核109例X线对照)

The radiological findings of pulmon ary tuberculosis:the analysis of 117cases in Nagquka,Tibet(with the comparison of 109cases in Zhanjiang,Guangdong)

目的提高对藏北那曲高原地区肺结核X线表现的认识。方法藏北那曲地区1996年7月至1999年9月间肺结核117例,初诊均拍摄胸部平片,并与沿海城市湛江同期、同年龄109例肺结核作对照,按1998年结核病新分类法分类,作者用双盲法分析两组的X线表现,用χ2检验作统计分析。结果(1)原发型肺结核比例高,占7.69%,其中成人比例高,占4.3%,对照组继发型肺结核比例高,占93.6%;(2)病变形态呈肺段大片状比例高,占16.2%,对照组呈斑片状比例高,占74.3%;(3)病变侵及4个肺野及以上占31.6%,对照组约占16.5%;少见部位多见,如下肺野结核,占12.8%,而对照组仅占0.9%;(4)以空洞病变为主比例并不高,占11.97%,对照组占32.1%。两组比较,均有显著性差异(均P<0.01)。结论西藏那曲地区肺结核X线表现有明显不同于南方沿海城市湛江的特点。

Objective It' s an investigation of the characteristic radiological findings of pulmo nary tuberculosis in population of Nagquka,northern T ibet.Method During July,1996to September,1999,the initial chest film(CXR)of 117cases of pulmonary tuberculosis from Nagquka,were compared with t he CXR of 109cases encountered in sea -side city Zhanjiang,with the same constituent ratio of age.According to the classification system fo r pul-monary tuberculosis of 1998,double-blinded investigation was made on t he two groups and(χ2test was applied for statistical analysis.Result Higher rate(7.69%)of primary pulmonary tuberculosis w ith higher ratio of adult patients were revealed in Nagquka group,while high rate(93.6%)of secondary pulmonary tuberculosis was found in the control group.More cases(16.2%)presented segmental consolidation in Nagquka group than that in control group,while in most of cases(74.3%)of control group,small patchy lesio ns were the predominant pattern.In 31.6%cases of the research group,4or more lung fields were involved,while in t he control group the ratio was 16.5%.More rare locations of the lesion,li ke inferior lung field were revealed in the research group,and the ratio o f rare location was 12.8%in research group and 0.9%in the control group.The rate of cavity(11.97%)was not high in research group,but 32.1%in control group.Statistical significance wa s indicated(P<0.01)by the(χ2test.Conclusion For the radiological manifestation s of pulmonary tuberculosis,there a re significant differences between the population of Nagquka and the sea -side city Zhanjiang.
