肛管直肠测压在肛门外伤中的应用

目的：研究肛管直肠测压对肛管损伤的定位诊断意义。方法：在杂种犬动物模型上，通过肛管直肠测压的方法，比较手术前后各导联的反映肛门括约肌复合体高压区的压力及间期变化情况，探讨肛管直肠测压在肛门外伤中的定位诊断价值。结果：术前静息和收缩压力及其间期差别无统计学意义。术后结果表现为第3导联的静息压与收缩压降低；收缩间期延长；静息间期无统计差异。术前术后的收缩间期无统计学差异，其余均有统计学差异。结论：在肛门外伤或手术后有局部的肛周括约肌损伤时对损伤部位的定位诊断有明确意义。对手术切口的选择有指导意义。

Application of anorectal manometry in the anal injury

Objective:To locate the anal injury by continuous anorectal manometry. Methods: The pressures and periods of the radial 8 channels manometry in the anus were compared on an experimental model of 10 dogs pre- and post-operatively. The statistics was carried out by student`s t test. Results: The resting and squeezing pressures and their periods had not statistical significance preoperatively, but they decreased postoperatively. The resting and squeezing pressure of channel 3 decreased comparing with channel 7 , the squeezing period prolonged, the resting period had not statistical significance. Conclusion: The anorectal manometry is a reliable method to locate the anal injury.
