摘要
目的功能性便秘可分为不同的类型,临床治疗方法也不尽相同,正确的分型对治疗方法的选择具有指导意义。本研究旨在探讨结肠通过时间检查对儿童功能性便秘分型的临床意义。方法结肠传输时间检查方法,采用不透X线标志物测定,分别于24h、48h、72h摄腹部平片各1张。根据肠内是否含气及结肠的走行,可区分小肠和结肠利用腹部平片骨性标志判断标志物在结肠中的位置,通过以上3个区域描述标志物的位置并计算不同时间各区的标志物数。运输指数(transitindex,TI):(48h,72h)TI=SRm/(RCm+LCm+SRm)。结肠排出率=(20-残留标志物数)/20×100%。为判断是结肠缓慢型或出口梗阻型,本研究应用传输指数TI,TI表示直肠乙状结肠区存留标志物数/全结肠标志物数之和,反映直肠乙状结肠区与其他部位标志物的比例。中位数为0,TI≤0.5说明STC可能性大,TI>0.5或接近1.0,提示标志物留存乙状结肠和直肠部位多,FOOC可能性大。结果正常组、便秘组结肠各区48、72h标志物潴留对比,均有显著差异。TI作为STC的动力学参数,可作为区别STC和FOOC的简单可靠指标。本组17例(占68%)FC患儿TI于48h、72hP均<0.5,符合结肠STC的特点。资料报道结肠STC占FC的64%,与本文结果接近。8例TI于48h、72h均>0.5,符合FOOC的特点。结论本研究结果显示结肠通过时间检查可以较准确地反映结肠传输功能是否正常,可评价功能性便秘患者结肠传输减弱的严重程度,正确、合理地进行分型对临床治疗具有重要指导意义。
Objective Functional constipation can be divided into different types. Clinical correct type of treatment the choice of guiding is significant. The purpose of this study is to use with functional constipation type of clinical significance. Methods Colonic transit time method X - ray marker measured, respectively, 24h, 48h, 72h Perturbation abdominal plain film of the 1 treatment methods are not the same. The colonic transit time to check on children of examination and not through the use of According to whether intestinal gas and colon course, can distinguish between the small intestine and colon using abdominal X - ray signs of bone markers to determine the loca- tion in the colon through the above three regions to describe the location of markers and calculate the different times in various districts of the marker a few. The transport index （transitindex, TI） ： （48h, 72h） TI = SRm / （RCm ＋ LCm ＋ SRm）. Colon discharge rate = （20 - the number of residual marker） / 20×100%. Results For judging slow colon or outlet obstruction, the research and application of transmission index TI , TI said the rectosigmoid area retained marker number / total colectomy and the number of markers, reflecting the rectosigmoid area and other parts of the proportion of markers . Median 0, TI≤ 0.5 Note STC likelihood, TI 〉 0.5 or close to 1.0, suggesting marker retained many parts of the sigmoid colon and rectum, FOOC possibility. Normal group, constipation group colon 48,72 hour markers district retention contrast, have significant differences. TI as the STC＇ s kinetic parameters can be used as the difference between STC and the simple and reliable indicators FOOC. 17 cases in this group （accounting for 68% ） FC children with TI in 48 h, 72 h were 〈0.5, in line with the characteristics of the colon STC. Information reported STC colon FC accounted for 64% , with results close to this article. 8 cases of TI in 48 h, 72 h were 〉 0.5, in line with the characteristics of FOOC. Conclusion The results of th
