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

ABSTRACT

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.
