吻合器痔上黏膜环切术前后肛肠动力学变化的临床观察

Clinical Observation on Kinetic Changes in the Anorectum before and after Procedure for Prolapse and Hemorrhoid

目的研究直肠肛门痔手术前后肛肠动力学的变化。方法对20例重度痔患者用直肠肛管测压法检测手术前后的肛管静息压、高压区长度、肛管蠕动波频率及直肠肛管抑制反射阈值等4项指标。对痔病患者手术前后肛肠动力学进行比较,并与正常对照组进行对比。结果手术后直肠肛管抑制反射阈值完全恢复,敏感率提高(P<0.05),肛管静息压较术前明显降低(P<0.05),高压区长度及肛管蠕动波频率手术前后差异无显著性意义(均P>0.05);以上4项指标术后与正常对照组比较差异均无显著性意义(均P>0.05)。结论吻合器痔上黏膜环切术可使重度痔患者的肛门静息压及直肠肛管抑制反射阈值恢复正常。

Objective To study the kinetic changes in the anorectum before and after procedure for prolapse and hemorrhoid. Methods The anorectal pressure was measured with 4 indexes, such as analrest pressure （ARP）, the district length of high pressure, anal wriggle wave frequency, the anorectal suppressed reflex threshold, in 20 cases of severe hemorrhoids. The comparisons, pre-and post-operation, and between 20 cases of severe hemorrhoids and 20 normal people, were made. ResultsAfter the procedure for prolapse and hemorrhoid, the anorectal suppressed reflex threshold in 20 cases of severe hemorrhoids was recovered completely, sensitive rate was raised （P〈0.05）, and ARP decreased obviously as compared with those preoperation （P〈0.05）, but the district length of high pressure and wriggle wave frequency had no difference perioperation （all P〉0.05）. Four above indexes post-operation had no difference between 20 cases of severe hemorrhoids and 20 normal people. Conclusion After procedure for prolapse and hemorrhoid, ARP and the anorectal suppressed reflex threshold of patients with severe hemorrhoid were recovered completely.
