Abstract:Objective To compare the efficacy and prognosis between minimally invasive puncture and traditional trepanation and drainage in the treatment of chronic subdural hematoma.Methods According to the inclusion and exclusion criteria, the quality of literature was evaluated strictly. The ReMan 5.0 software was used to perform meta-analysis of enrolled clinical randomized control trials (RCTs).Results Eleven clinical RCTs with a total of 909 patients were enrolled as subjects. There were significant differences in operation time, amount of intraoperative bleeding, amount of residual liquid after operation, postoperative drainage time, cure rate, incidence of complications, and recurrence rate between the two surgical approaches (MD=-28.31, 95%CI [-29.53,-27.09], P <0.00001; MD=-27.50, 95%CI [-36.89,-18.11], P<0.00001; MD=-6.34, 95%CI [-8.51,-4.18], P<0.00001; MD=1.08, 95%CI [0.21, 1.95], P=0.01; RR=1.22, 95%CI [1.07, 1.40], P=0.004; RR=0.23, 95%CI [0.11, 0.48], P<0.0001; RR=0.29, 95%CI [0.16, 0.53], P<0.0001). According to the analyses, there was no publication bias in enrolled studies.Conclusions Minimally invasive puncture and drainage is substantially superior in operation time, amount of residual liquid after operation, postoperative drainage time, and cure rate compared with traditional trepanation and drainage. Furthermore, minimally invasive puncture and drainage can substantially reduce postoperative complications and hematoma recurrence.
