目的：对照观察PPH加LigaSureTM痔切除术治疗环状混合痔的临床疗效。方法：将62例环状混合痔PPH环切后痔回缩不全患者随机分为对照组和治疗组各31例，治疗组加用LigaSureTM痔切除术，对照组加用传统外剥内扎术，观察疗效情况、术中出血量、手术时间、术后疼痛评分、术后肛缘水肿、创面愈合时间、术后肛门狭窄等临床情况。结果：治疗组与对照组相比，其术中出血量、手术时间、术后疼痛评分有统计学意义(P<0.05)，治疗组优于对照组；但两组在疗效、术后肛缘水肿、创面愈合时间、术后肛门狭窄等方面无统计学意义(P>0.05)。结论：对于环状混合痔PPH环切后痔回缩不全患者加LigaSureTM痔切除术疗效可靠，并具有术中出血量少、手术时间短、术后疼痛轻的优点，是一种安全有效、操作方便、术后痛苦小的手术方法，值得临床推广应用。

English Summary:

To observe the clinical effects of PPH & LigaSureTM hemorrhoidectomy for severe circumferential mixed hemorrhoids. Methods:A total of 62 severe circumferential mixed hemorroids patients who were operated PPH with incomplete hemorrhoid retraction were randomly divided in control group (31 patients) and treat group (31 patients). Apply LigaSureTM hemorrhoidectomy to the treat group, and traditional Milligan Morgan to the control group. Curative effects, blood loss during operation, operation duration, postoperative pain scores, postoperative edema of anal, wound healing time and postoperative anal straitness were observed. Results: There was significant difference in blood loss during operation, operation duration, postoperative pain scoring between the treat group and control group(P<0.05), the former was superior to the latter, but no significant difference of curative effects, postoperative edema of anal, wound healing time or postoperative anal straitness have been detected(P>0.05). Conclusion: For severe circumferential mixed hemorrhoids patients that are operated with PPH with incomplete hemorrhoid retraction, LigaSureTM hemorrhoidectomy can raise clinical curative effects with obvious merits including less blood loss during operation, shorter operation duration and rather subtle pains. Therefore, it is considered as convenient operation with safety, efficacy and less pains and is worthy of clinic application.
