The longest interval were above the 11 years (21.9%) and the shortest interval were below the 1 month(15.6%). 4) The main pathologic findings of reoperated 32 cases were epidural fibrosis(31.2%), incomplete disc removal+epidural fibrosis(31.2%), new disc herniation(21.8%), foraminal stenosis(9.4%) and opposite site herniation(6.3%) in orders. 5) The results of 32 reoperated cases were good(43.7%), excellent(21.8%), fair(18.7%) and poor(15.6%) in orders.
