目的 对痔切除吻合器痔上黏膜环切术（PPH）与传统手术在治疗混合痔环状脱垂或内痔环状脱垂的疗效进行比较。方法 回顾性分析2002年1月至2004年9月西苑医院收治的832例经内镜确诊为内痔及混合痔患者的临床资料。结果 PPH组： 混合痔247例，治愈228例（92.3%），显效19例（7.7%）; 内痔168例均治愈（100%）； 术后发生大出血2例（0.5%），住院时间3.1~6.3 d，无一例创面感染。传统手术组： 混合痔229例中治愈215例（93.9%），显效14例（6.1%）; 内痔188例中治愈175例（93.1%），显效13例（6.9%）； 术后发生出血3例，肛管狭窄12例，并发症发生率为3.6%，住院时间26.2~27.1 d。结论 对痔的环形脱垂，采用PPH手术并与外痔切除或外剥内扎方法相结合，具有手术操作简单、安全、术后疼痛轻、恢复快等特点，优于传统的外剥内扎手术。
目的探讨痔切除吻合器痔上粘膜环切术（PPH）的临床应用价值。方法采用33 mm痔切除吻合器痔上粘膜切除术对严重脱垂性痔30例进行治疗。结果全组病例平均手术时间10分钟，术后住院时间1～3天，脱出痔块均回缩，切除直肠粘膜完整率达98%，术后90%的患者无肛门疼痛，随访3个月，28例满意，2例基本满意。结论采用痔切除吻合器痔上粘膜环切术治疗严重脱垂性痔是一种新技术，其手术操作简单，具有安全、有效、手术时间短、术后疼痛轻、恢复快等特点，有望替代传统的治疗方法。
Objectives To evaluate the effect of metrinidazole treatment after conventional hemorrhoidectomy pain in patients with third and fourth degree hemorrhoids. Methods We searched the Cochrane Library (Issue 1 2009), PubMed (1966 to March 2009), EMbase (1974 to March 2009), SCI (1974 to March 2009), CBM (1978 to March 2009), CNKI (1994 to March 2009), and VIP (1989 to March 2009) to identify randomized controlled trials or quasi- randomize controlled trials of metronidazole versus placebo for treating post hemorrhoidectomy pain. We evaluated the quality of the included studies by using the Handbook 4.2.6 recommend standards and analyzed data using the Cochrane Collaboration’s RevMan 4.2.10. Results We included seven randomized controlled trials or quais-randomized controlled trials (n=553). Meta-analyses showed that there were statistical differences between metronidazole and placebo in pain after hemorrhoidectomy and the use of an additional dose of analgesia. Conclusions The current evidence shows that metronidazole relieves the pain after conventional hemorrhoidectomy and reduces the additional used of analgesics. Further high quality, large sample randomized controlled trials should be carried out.
目的:探讨吻合器痔上黏膜环切吻合术(PPH术)+外痔切除和单纯外剥内扎术治疗重度环状混合痔的临床效果。方法:对收治的48例III,IV度环状混合痔患者随机分为2组,分别采用PPH术+外痔切除术和单纯外剥内扎术予以治疗的疗效进行比较。结果:通过对手术时间、术中出血、疼痛程度、住院时间、患者满意度等进行比较观察,表明PPH术+外痔切除具有明显优势。结论:PPH术+外痔切除术仍能保持单纯PPH优势,克服其不足之处,较传统外剥内扎术治疗重度环状混合痔有明显的优势。
目的 比较吻合器痔上黏膜环切术(PPH)与传统痔切除术(Milligan-Morgan，MM)治疗混合痔的临床疗效。方法 200例混合痔患者中行PPH和MM治疗各100例，比较2组患者的疗效及并发症。结果 PPH在疗效及术后并发症发生方面与MM组比较，差异均无统计学意义（P＞0.05）。结论 在治疗混合痔方面PPH不优于MM。
