Abstract: Objective　To compare the clinical efficacy and safety of TESSYS technology in the treatment of lumbar disc herniation with and without a drainage tube.Methods　From January 2015 to March 2016，110 patients with lumbar disc herniation，who underwent percutaneous transforaminal endoscopy using TESSYS technology in the Department of Bone Tumor Surgery of the First Affiliated Hospital of Xinjiang Medical University were enrolled and divided into two groups：the no-drainage group with no drainage tube（n=53） and the drainage group with a drainage tube（n=57），according to the random grouping method of region group.The postoperative drainage volume of the drainage group was observed.The operation time，intraoperative blood loss，hospitalization time，incidence of postoperative complications and the postoperative activity time were compared between the two groups.A visual analogue scale（VAS） and the Oswestry Disability Index（ODI） were completed 1 day before operation，1 day after the operation，1，3 and 6 months after the operation，and 1 year after the operation.Results　The postoperative drainage volume of the drainage group was（50±10） ml，and the duration of drainage tube placement of this group was（26.0±2.2） h.There were no significant differences in operative time，intraoperative blood loss and surgical complications between the two groups（P>0.05）．The duration of hospitalization and the time to be able to stand on the groud after the operation of the patients in the no-drainage group were significantly shorter than those of the patients in drainage group（P<0.05）．There were no correlations between treatment methods or time and the VAS score（Finteraction=2.981，P>0.05）．The effect of treatment on VAS was significant（Ftreatment=20.200，P<0.05），but the effect of time on the VAS score was not significant（Ftime=4.241，P>0.05）．The VAS for the drainage group was significantly higher than that for the no-drainage group on the first day after the operation（P<0.05）．There was no correlation between treatment method and time according to the ODI（Finteraction=2.298，P>0.05）．The treatment method and time had no significant effects on the ODI score（Fgroup=1.090，Ftime=4.391，P>0.05）．Conclusion　Use of the TESSYS technology for percutaneous transforaminal endoscopic discectomy treatment in lumbar disc herniation without drainage tube placement does not increase the incidence of complications，indeed it can reduce postoperative pain as well as shortening the duration of hospitalization and improving postoperative activity.
