Clinical Study Of Reservations Of Nerve Root Accompanying Vascular Through Percutaneousendoscopic Lumbar Disc Herniation

ObjectiveObserved a correlation between Reserved nerve root Concomitant Vessels and Numbness discomfort after Percutaneous endoscopic treatment of lumbar disc herniation.MethodsRetrospective analysis 133 patients with lumbar disc herniation patients was admitted in spinal ward,Wuhan General Hospital of Guangzhou Military Region from January 2014 to December 2015 And all patients were under local anesthesia along with monitoring during the surgery,Of which 71 patients preserved intraoperative nerve root intact accompanying vessels,with 62 patients not.Observed Postoperative discomfort numbness and record operation time.Using visual analog scale(VAS)scores to assess low back pain preoperative and postoperative day,three days,1 month,3 month,a year after;Lumbar JOA score(29 points system)to evaluate the relief of symptoms before surgery and postoperative day,three days,1 month,3moths and a year after;ODI Disability Index(Oswestry disability index,ODI)score to assess the function of the lumbar spine preoperative and postoperative a mounth,3 montn,and a yearResult133 cases of patients were successfully operated,without surgery procedure changed,intraoperative nerve root injuried and cerebrospinal fluid leaked,and leg pain reliefed,no intervertebral infection and other complications.133 cases of patients were followed in 3 month,110 patients were followed up for more than one year,Observer Group lost 16 cases after a year,a 22.5%dropout rate,and Comparison group 7 seven cases,a rate of 11.3%.all patients were followed up ranged from 3 to 22 months,with an average of 14.5 months through regular review,telephone and E-mail follow-up.Observer group operative time was 55~110min,an average 71.5min;and comparison group operative time 54~82min,an average of 62.lmin,with a significant differences(P<0.05).Straight leg raising test before and after surgery,postoperative hospital stay was no significant difference(P>0.05)bettween two groups.After each stage VAS score,JO A score,ODI score and preoperative VAS score,JOA score,ODI scores were statistically significant(P<0.05)in observergroup and in comparison group seperitely.Postoperative VAS score,JOA score and ODI scorescompared between groups were normally distributed by using homogeneity of variance test,and Postoperative VAS,was statistically significant(P JOA score between groups<0.05),postoperative ODI scores between groups was not statistically significant(P>0.05)through independent samples t-test ConcluionPercutaneous endoscopic had the advantage of precise targeting,trauma,postoperative recovery,shorter operative time,less complications,little impact on the stability of the spine,reliable short-term effect,etc in the treatment of lumbar disc herniationIntraoperative nerve root intact concomitant vascular patients has less possibility of mild limb of lumbar discomfort and numbness after surgery than those without reservations,and the recent effect is significant.
