简介:摘要目的观察分析PPH手术方式治疗痔疮患者的临床效果,并探讨体会。方法随机选取我院肛肠外科在2011年7月~2012年1月期间收治入院的经视诊、直肠指检以及肛门镜检查确切诊断为痔疮的患者25例,均行PPH手术方式治疗,观察分析其疗效,以患者治愈率、平均住院时间、住院舒适率、术后并发症发生率、半年复发率等为指标。结果经治疗,患者均治愈,治愈率为100%,平均住院时间为(3.5±1.4)天,住院感觉非常舒适15例,比较舒适9例,欠佳1例,住院舒适率为96%,术后发生并发症1例,并发症发生率为4%,6个月后无患者复发,半年复发率为0。结论对于痔疮患者,采用PPH手术方式治疗疗效肯定,优点较多,值得在临床肛肠外科大力推行。
