In this retrospective study, 85 patients previously operated on for lumbar disc herniation who had undergone reoperation due to persistent pain or recurrence of the symptoms were investigated. The surgical findings were: recurrent herniation (20%), epidural fibrosis alone (36.4%), small recurrent herniation with epidural fibrosis (28.2%), herniation at another level (10.6%), spinal stenosis (2.4%), lumbar pseudomeningocele (1.2%) and adhesive arachnoiditis (1.2%). The overall success rate of re-operation was 60%. The best results were obtained in recurrent disc herniation (47.1% excellent and 35.3% good results) and in herniation at another level (77.8% excellent and 22.2% good). Re-operation in epidural fibrosis had less-satisfactory results (29.1% excellent and 12.9% good).
