Thirteen patients treated with percutaneous discectomy for relapse of lumbar disc herniation were evaluated. All patients had been treated by partial laminectomy and herniotomy in the first operation.The period between the first operation and percutaneous discectomy ranged from 4 to 204 months, mean 76 months. The observation period after the second operation ranged from 12 to 39 months' mean 25 months.According to MacNab's criteria, the results of surgry were excellent in 1 patient, good in 11 patients, and poor in 1 patient.Percutaneous discectomy is simple, safe and only slightly invasive since it causes no direct damage to the dura or nerve roots. Since 1989 we have performed this operation on 363 patients with lumbar disc herniation, with no serious surgical complications encountered.The study of our series suggests that this techique is a useful preocedure for treating relapse of lumbar disc herniation.
