[Treatment of lumbar intervertebral disc herniation and sciatica with percutaneous transforaminal endoscopic technique].
OBJECTIVE
To analyze the clinical effects of percutaneous transforaminal endoscopic technique in treating lumbar intervertebral disc herniation and sciatica.


METHODS
From June 2011 to January 2012,the clinical data of 46 patients with lumbar intervertebral disc herniation and sciatica underwent percutaneous transforaminal endoscopic technique were retrospectively analyzed. There were 28 males and 18 females,ranging in age from 11 to 77 years old with an average of (39.7_ 15.3) years old,20 cases were L5S1 and 26 cases were L4,5. All patients had the symptoms such as lumbago and sciatica and their straight-leg raising test were positive. Straight-leg raising test of patients were instantly repeated after operation;operative time,volume of blood loss,complication, length of stay and duration of back to work or daily life were recorded. The clinical effects were assessed according to the VAS,JOA and JOABPEQ score.


RESULTS
All operations were successful,postoperative straight-leg raising test were all negative. Operative time,volume of blood loss,length of stay,duration of back to work or daily life,follow-up time were (93.0+/-28.0) min, (20.0+/-9.0)ml, (3.1+/-1.5) d, (11.6+/-4.2) d, (13.9+/-1.6) months,respectively. VAS score of lumbar before operation and at the 1st and 3rd,6th,12th month after operation were 5.3+/-1.2,1.9+/-1.1,1.0+/-0.8,0.9+/-0.8,0.8+/-0.6,respectively;VAS score of leg before operation and at the 1st and 3rd,6th,12th month after operation were 7.2+ 1.2,0.8+/-1.2,0.5+/-0.8,0.5+/-0.8,0.3+/-0.8,respectively. Five factors of JOABPEQ score,including lumbar pain,lumbar function, locomotor activity,social life viability and mental status,were respectively 27.0+/-30.6,37.3+/-27.4,38.5+/-26.6,33.0+/-13.7,55.4+/-19.0 before operation and 83.6+/-24.8,89.4+/-15.7,87.0+/-17.9,58.4+/-14.6,79.5+/-13.4 at final follow-up. Preoperative and postoperative JOA score were 9.1+/-2.6 and 27.3+/- 1.7, respectively. The postoperative VAS,JOA and JOABPEQ score had significantly improved (P<0.05).


CONCLUSIONS
Percutaneous transforaminal endoscopic technique is safe and effective method in treating lumbar disc herniation and sciatica,it can fleetly relieve pain and the patient can recover daily life and work after treatment.
