功能性结肠运输时间延长与便秘的相关性

Relationship between fundional elongated colonic transit time and constipation

目的 通过回顾性比较分析,探讨结肠运输试验检查在便秘病因学诊断所起的作用。方法 收集3年中根据Agachan计分确定为便秘并至少做过一次结肠运输实验的病人87例,分为:A组,全结肠运输时间正常组;B组,全结肠运输时间延长组。比较分析各组乙直肠运输占全结肠运输的比(简称乙全比)值过小的情况。结果A组32例,占总例数的36.8％;B组55例,占63.2％。A组乙全比过小者的有10例,占31.3％;B组9例,占16.4％。经x2检验,A,B两组之间的差异显著(P<0.01)。结论 结肠运输时间的测定对于便秘病因的确定有重大帮助,其中乙直肠运输功能的测定至关重要。

Objective To retrospectively analyze the role of colonic transit test in diagnosis and aetiology of constipation. Methods 87 cases of constipation diagnosed under Agachan scoring system and having completed transit test at least once were enrolled. All cases were divided into two groups: group A have normal colonic transit time, group B have clongated transit time. A comparison of the ratio of rectosigmoid transit by total colon (RRT) between group A and B. Result 32 cases were enrolled in group A and 55 in group B. Low value of RRT was presented in 10 cases out of 32 in group A (31. 3% ), while in group B the abnormality was observed in 9 cases out of 55 (16.4%). A statistical difference between the two group was revealed by x2 test (P < 0.01). Conclusion Colonic transit test helps the confirming the aetiology of constipation, and the evaluation of rectosigmoid transit function is especially valuable.
