外剥内扎加部分括约肌离断术治疗环状混合痔的临床疗效

External Dissection ＆ Internal Ligation plus Interruption for Partial Sphincter in the Treatment of Circum- ferential Mixed Hemorrhoids

为探讨外剥内扎加部分内括约肌和外括约肌皮下部离断术治疗环状混合痔的临床疗效及安全性，将我院收治的90例环状混合痔患者按照手术方法不同分为治疗组（外剥内扎加部分内括约肌、外括约肌皮下部离断术，48例）和对照组（单纯外剥内扎术，42例），比较两组患者手术疗效、创面愈合时间、术后并发症等情况。结果显示，两组患者总有效率、创口愈合时间比较差异无统计学意义，P〉0．05；但治疗组住院时间明显短于对照组，P〈0．05，术后并发症明显少于对照组，P〈0．05或P〈0．01。结果表明，外剥内扎加部分内括约肌和外括约肌皮下部离断术治疗环状混合痔安全，疗效肯定，患者术后并发症少、恢复快，值得临床推广应用。

In order to explore the clinical effect terruption for parial internal sphincter and sub ential mixed hemorrhoids,the 90 patients with and safety of external dissection ＆ internal ligation then incutaneous external sphincter in the treatment of circumferthis hemorrhoids who admitted and received the therapy in author＇s hospital were selected into this study, and according to different procedures adopted were divided into treatment group （received above combination procedure）, n =48, and control group（ n = 42）, alone external dissection ＆ internal ligation; then the surgical effect, the time for wound-surface healing and complication status were compared between both groups. As results, in total effective rate, the time for wound-surface healing there was no statistical difference（ P〉0.05） between both groups, but, hospitalization stay of treatment group was significantly shorter than that of control group（ P〈0.05 or P〈0.01）. Results show that this combination procedure is safe, of certain effect, less postoperative complication and faster recovery, thus worthy to be popularized to use clinically.
