摘要
目的:对系统性硬皮病(PPS)患者进行食管动力功能影像学研究,并对治疗前后的结果进行比较,旨在提高食管造影在PSS中的应用价值。方法:采用食管气钡双重造影,钡剂浓度为220%。正常组和PSS组各70例,其中PSS组中22例进行了治疗后复查。结果:正常组立、卧位排空时间分别为(7.906±2.068)s和(12.697±3.97)s。70例PSS组排空时间、管腔直径、粘膜改变等均有不同程度异常。22例治疗前后对比,立位排空时间及卧位排空指数P<0.01,有统计学意义。结论:PSS组立位、卧位排空时间与健康组相比差异有显著性意义。22例治疗后复查者,立位排空时间和卧位钡剂排空指数是观察食管动力功能较为有效的指标。通过各项影像观察内容,明确食管影像动力学改变,进行早期诊断。可用于治疗前后对比,有效说明疗效判定。
Objective： For the purpose of improving its practical and clinical value, the radiographic esophageal dynamics of patients with PSS were studied and the relative pre- and post-treatment signs were correlatively compared. Methods： In our study,a collection of 140 patients was involved and divided into 2 groups of 70 patients each, designated as ＂normal group＂ and ＂PSS group＂ respectively, Air and barium double contrast esophageal radiographic examination was used. The concentration of the barium emulsion was 220% （W/V）. In the PSS group,22 cases had been radiographically re-examined after relative treatments. Results： The emptying times in patients of the normal group in standing and lying position were （7. 906±2.068）s and （12. 697±3.97）s respectively. In the 70 cases of group PSS, significant differences were shown in emptying times, lumen diameter and mucous fold changes of the esophagus in comparison to those of the normal group. There was statistical significance in the emptying times of the 22 radiographically re-examined pSS cases pre- and posttreatment. Conclusion： The emptying times of esophageal barium meal in patients with PSS were significantly different to those of the normal group in our study. In the 22 cases of PSS with posttreatment radiiographic re-examination,it seemed that the value of emptying times in both standing and lying positions might be an efficient parameter for the study of esophageal dynamic functions. Esophageal dynamic changes, early diagnosis and also the evaluation of post-treatment therapeutic effect could be acquired through the observation and interpretation of the esophageal radiographic barium meal signs of patients with PSS.
