ABSTRACT

Objective A meta-analysis was performed to assess the routine use of drainage after thyroid and parathyroid surgery with respect to the postoperative hematoma、haemorrhage、wound infection、seroma and hospital stay.Methods Medline、EMBASE、Cochrane Controlled Trials Register and China Biological Medicine Disk from Jan 1966 to Apr 2007 were searched for the randomized controlled trials of the routine use of drainage after thyroid and parathyroid surgery.Eleven studies were enrolled into the analysis.The details about the trial design,characters of the subjects,results of the studies were reviewed by two independent authors and analysed by using Revman4.2 software.Results Compared the drain group with non drain group,the drain group was not associated with significantly lower incidence of hematoma(OR=1.31,95%CI0.71～2.42,P=0.38) 、wound infection(OR=1.51,95%CI0.53～4.28,P=0.44)、hemorrhage(OR=1.21,95%CI0.35～4.24,P=0.77) and seroma(OR=0.50,95%CI0.22～1.15,P=0.10).Length of hospital stay between the two groups was significantly different(OR=1.29,95%CI0.69～1.88,P
