封闭式高压负压吸引对直肠肿瘤腹会阴联合切除会阴切口愈合的促进作用

目的探讨封闭式高压负压吸引对直肠肿瘤腹会阴联合切除术（APR）后会阴切口一期愈合的影响。方法按随机数字表法．将2009年1月至2011年1月间武汉同济医院胃肠外科中心收治并行APR手术的120例直肠肿瘤患者．随机分为试验组（61例,行封闭式高压负压吸引）和对照组（59例,行骶前引流）。比较两组术后会阴切口引流量、一期愈合率及愈合时间。结果试验组和对照组术后前3d会阴切口引流量分别为（448．1±142．9）ml和（548．3±190．6）ml,第3天引流量分别为（28．1±12．7）ml和（125．9±84．3）ml,一期愈合率分别为93．4％（57／61）和74．6％（44／59）,愈合时间分别为（13．5±3．5）d和（20．1±5．1）d,差异均有统计学意义（均P〈0．01）。结论封闭式高压负压吸引能促进APR手术后会阴切口的一期愈合。

Effect of closed high-pressure suction drainage on primary healing of perineal wound after abdominoperineal resection for rectal cancer

Objective To evaluate the impact of closed high-pressure suction drainage on the healing of the perineal wound after abdominoperineal resection. Methods Patients undergoing rectal abdominoperineal resection in the Wuhan Tongji Hospital from January 2009 to January 2011 were randomized into two groups including the study group（n=61, closed high-pressure suction drainage） and the control group （n=59, presacral drainage）. The drainage volume, primary healing rate, and the healing time of perineal wounds were compared. Results The total volume of the drainage in the first 3 days was （448.1±142.9） ml in the study group and （548.3±190.6） ml in the control group, the volume of the drainage on the third day was （28.1±12.7） ml and （125.9±84.3） ml respectively. The primary healing rate was 93.4%（57/61） in the study group and 74.6% （44/59） in the control group, the healing time was （13.5±3.5） days and （20.1±5.1） days respectively. Conclusion Closed high-pressure suction drainage may promote perineal wound healing following rectal abdominoperineal resection.
