摘要目的：比较一次性包皮环切缝合器与传统包皮环切术（背侧切开包皮环切术）治疗包皮过长及包茎患者的临床疗效及安全性。方法将2015年11月至2016年5月门诊就诊的161例包皮过长及包茎患者随机分成两组，缝合器组89例，包皮环切术中采用包皮环切缝合器；对照组72例，行传统包皮环切术治疗。结果缝合器组和对照组手术时间分别为（3.8±0.5）和（31.6±2.7） min，出血量分别为1.0（0.9，1.2）和6.2（5.7，7.0）ml，差异均有统计学意义（F＝71.21，P＝0.000；Z＝－10.90，P＝0.000）；术中疼痛视觉模拟评分分别为（1.4±0.6）和（2.9±0.8）分（F＝2.08，P＝0.151）。切口愈合时间分别为（14.0±1.3）和（16.8±2.1）d（F＝0.10，P＝0.754）；缝合器组术后2～3 d可自行拆除敷料，不需再次换药，对照组需换药2～3次／例；术后并发症发生率分别为10％（9／89）和4％（3／72），术后外观满意率分别为98％（87／89）和94％（68／72），差异均无统计学意义（χ2＝2.04，P＝0.153；χ2＝0.47，P＝0.494）。结论应用包皮环切缝合器行包皮环切术较传统手术时间短、失血量少。

abstractsObjective To compare the safety and effectiveness of disposable circumcision suture device (DCSD) with conventional circumcision in surgical treatment of phimosis and redundant prepuce . Methods One hundred and sixty one patients with phimosis or redundant prepuce were randomly assigned to be treated by circumcision using disposable circumcision suture device ( DCSD group , n =89 ) or conventional circumcision (CC group,n =72),respectively.Results The operation time was (3.8 ± 0.5)min in DCSD group and (31.6 ±2.7)min in CC group (F=71.21,P=0.000),blood loss was 1.0(0.9, 1.2)ml in DCSD group and 6.2(5.7, 7.0)ml in CC group (Z =-10.90,P=0.000).There were no significant differences in intraoperative pain score (1.4 ±0.6 vs.2.9 ±0.8, F=2.08, P=0.151) and wound healing time [(14.0 ±1.3) vs.(16.8 ±2.1) d, F=0.10, P=0.754] between two groups.There was no need to change the dressing for patients in DSCD group 3 days after the operation , while patients in CC group changed dressing 3 times after the operation .No significant differences in postoperative complication rate [10%(9/89) vs.4%(3/72),χ2 =2.04,P=0.153] and satisfaction rate with the penile appearance [98%(87/89) vs.94%(68/72), χ2 =0.47,P=0.494] were found between two groups .Conclusion DCSD exhibits superiority over CC for shorter operation time and less blood loss in circumcision .
