ABSTRACT

Objective To investigate the application of abdominal drainage after liver resection.Methods From Jan 2008 to June 2009,210 consecutively admitted patients undergoing liver resection by the same surgical team were chronologically allocated into drainage group(120)and non-drainage group (90).Patient's preoperative characteristics,operation-related factors,postoperative complications and hospital stay were compared between the two groups.Results Postoperative complications were comparable between the two groups,which was not significantly different among preoperative characteristics and operation-related factors(P>0.05).Mortality was 0.8% in drainage group and 1.1% in non-drainage group,again,the difference was not significant(X~2=0.042,P>0.05).Snrgical complications were significantly higher in drainage group than in non-drainage group,especially for abdominal infection and ascites occurrence(P<0.05).The hospital stay was significantly longer in the drainage group(13.1 ±5.2)days than the non-drainage group(11.4±5.6)days.Conclusions Postoperative abdominal drainage is not necessary for patients undergoing liver resection,furthermore,abdominal drainage increases postoperative complications.
