| 目的：评价钡糊法排粪造影(DTB)与钡液法排粪造影(DBS)对功能性出口梗阻的诊断价值。方法：25例便秘者均于检查当日进行钡液法与钡糊法排粪造影自身对比。结果：直肠平均内径钡糊法比钡液法大1.16cm；直肠平均容积钡糊法为钡液法的2.2倍；发现异常的24例钡糊法均显示钡剂梗阻或嵌塞，钡液法仅2例有少量滞留；排粪(空)时间钡糊法平均每例9s，钡液法为2.5s；显示出口梗阻原因的能力钡糊法较优者14例，钡液法较优者6例。结论：对功能性出口梗阻的排粪造影检查以钡糊法为好，先灌入少量高浓度钡液能提高造影质量。 |

| Abstract: |
| Objective: To select the better method for the examination of functional outlet obstruction, the defecography with thickened barium (DTB) and the defecography with barium suspension (DBS)were compared and evaluated objectively. Methods：The comparison of DBS and DTB were carried out on the same day in 25 cases of constipation. Results: The average internal rectal diameter of DTB was 1.16cm larger than that of DBS. The average rectal volume of DTB was 2.2 times as large as of DBS. In 24 abnormal cases detected, the blocking and inlaying of barium were all revealed by the DTB and little barium remained in only 2 cases by the DBS. The average time of defecating with DTB were 9s, and with DBS were 2.5s. The capability of revealing the cause of obstruction at outlet were better in 14 DTB cases and better in 6 DBS cases. Conclusion: For the examination of functional outlet obstruction, the DTB is better than the DBS. The revealing quality can be improved if little concentrated barium suspension is injected before the thickened barium. |
