Endoscopic Contrasted With Open Carpal Tunnel Release For Carpal Tunnel Syndrome: A Meta-analysis

Objective The purpose of this study was to determine the effect of endoscopic andopen operation by meta-analysis.Method Relevant literatures were searched using MEDLINE,Cochrane library,CNKI,Wanfang Data and related meetings. Randomized controlled trials thatcompared endoscopic and open operation were included in the meta-analysis from1989to2014. All literatures were assessed by the inclusion and exclusion criteria,quality assessment and data abstraction. The meta analysis was performed by RevMan5.0software.Results Twenty-two literatures were included into the meta analysis. There were1962cases including930cases in the endoscopic group and1032cases in the opengroup.There was no difference between groups in time of operation （MD=1.96；95%CI [-0.25，4.18]，P=0.08）,postoperative remission (MD=0.87；95%CI [0.55，1.39]，P=0.57),postoperative complications (MD=0.67；95%CI [0.42，1.05]，P=0.08) andsatisfaction (MD=1.58；95%CI [0.96，2.60]，P=0.07).The cases treated withendoscopic carpal tunnel release showed greater pinch strength (MD=0.77；95%CI[0.13，1.41]，P=0.02) and grip strength (MD=5.25；95%CI [0.03，10.48]，P=0.05).Conclusion Patients treated with endoscopic group showed greater pinch strengthand grip strength.There was no difference between groups in time ofoperation,postoperative remission,postoperative complications and satisfaction.
