摘要
目的探讨慢性功能性便秘患者排便频率与结肠通过时间的关系。方法采用一次性口服20粒不透X线标志物后每24h连续7d摄片对168例患者进行结肠运输试验。测定全结肠及其分段结肠通过时间(CTT)。比较排便频率(次/周)与结肠通过时间的关系。结果全结肠和分段结肠通过时间在低排便频率(03次/周)和高排便频率(≥3次/周)便秘病人间差异无统计学意义(P>0·05)。结肠通过时间正常和异常便秘病人均以低排便频率为主,分别为58·6%和48·8%,但二者间差异无统计学意义(P>0·05)。结论慢性便秘排便频率与结肠通过时间无相关性,提示排便频率不能判断结肠传输是否正常。
Objective To investigate the possible relation between defecation frequency and colonic transit time in patients with chronic functional constipation（CFC）. Methods The colonic transit studies were performed by obtaining X-rays every 24 h for seven successive days after ingestion of 20 radiopaque marks in 168 patients with chronic functional constipation. Total and segmental colonic transit time （CTY） were measured and compared with defecation frequency. Results The CTrs between the patients with low defecation frequency （0 ～ 3/week ） and those with high defecation frequency （ ≥3/week ） displayed no significant difference （ P 〉 0. 05 ）. No significant difference of defecation frequency were found between the patients with normal or abnormal CTT （P〉0. 05 ） , although low defecation frequency preponderance predominated in both group patients （58, 6% and 48.8%, respectively）. Conclusions No significant correlation between defecation frequency and CTT could be demonstrated in the study. The results suggest the defecation frequency in patients with CFC can not indicate the colonic transit condition.
