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患者 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 5 5例 ,占 6 3.2 %。 A组乙全比过小的患者有 10例 ,占 31.3% ;B组 9例 ,占 16 .4 %。经χ2 检验 ,A,B两组之间的差异显著 (P <0 .0 1)。结论 :结肠运输时间的测定对于便秘病因的确定有重大的帮助 ,其中乙直肠运输功能的测定至关重要
Objective: To investigate the role of colon transport test in the diagnosis of constipation etiology by retrospective comparative analysis. Methods: Eighty-seven patients with constipation and at least one colonic transit test were scored according to Agachan score in three years. They were divided into group A, group with normal colon transport time, group B with extended colon transport time. Comparative analysis of each group of B-transport of total colon transport ratio (referred to as B full ratio) value is too small. Results: A group of 32 cases, accounting for 36.8% of the total number of cases; B group 55 cases, accounting for 6 3.2%. In group A, there were 10 cases of patients whose B ratio was too small, accounting for 31.3%; 9 cases of B group, accounting for 16.4%. After χ2 test, the difference between A and B groups was significant (P <0.01). CONCLUSIONS: The determination of colon transit time is of great help in determining the cause of constipation, of which determination of the function of the B-rectum is crucial
