We reviewed 9 cases (4 men, 5 women, mean 49.9 years) who underwent revision surgery after Microendoscopic Discectomy (MED). Primary causes of revision were residuum in four, relapse in two and instability in three patients. Residuum and relapse were treated by the Love method in five cases and in one case by osteoplastic discectomy. Cases of instability were all treated by anterior lumbar interbody fusion. In all cases, the residual lumbar disc herniation migrated. Preoperative and postoperative hernia disc level was at L5/S in four revision cases. These results suggest that more attention to migrated lumbar disc herniation and lumbar disc herniation at L5/S disc level is necessary during surgery.
