Abstract:
Between January 1995 and May 1998, 177 patients with proven lumbar disc herniation were treated by microdiscectomy or by percutaneous endoscopic discectomy(PED). Among them, 43(24.2%) patients underwent PED and were followed for long term outcome. We included only those patients who were followed up more than 13 months. Three patients who did not improved immediately after PED and underwent microdiscectomy were excluded for this study. Of remaining 40 patients, there were 22 men and 18 women who ranged in age from 23 to 68 years (mean 38.1 years). The disc herniations were located at L1-2(1), L2-3(1), L3-4(1), L4-5(26) and L5-S1(11). Three patients were treated by biportal approach. The mean follow up period was 34.7 months(range 13-47 months). Overall, excellent and good results were achieved in 12(30%) and 19(47.5%) patients, and fair and poor results in 7(17.5%) and 2(5%) patients, respectively. Thirty-eight(95%) patients returned to their previous works and the mean duration was 5.7 months. Thirty-three(82.5%) patients answered that they would recommend this procedure to others. There was no complication except for one patient who suffered from discitis. The indication of PED is restricted to contained or small subligamentous lumbar disc herniation without stenosis, spondylolisthesis and sequestration. PED can be performed under local anesthesia and tissue trauma, risk of epidural scarring, hospitalization time and postoperative morbidity are minimal. The result of the present study justify the assumption that PED can be a surgical alternative for patients suitable for its indications.
