    Bottom line The evidence indicated that operative time, blood loss and complication rates were significantly reduced with percutaneous endoscopic lumbar discectomy in patients with recurrent lumbar disc herniation in comparison with open lumbar microdiscectomy. Whereas, the difference between the treatment groups were similar in terms of pain reduction, global perceived effect (MacNab score), re-operation and recurrence rate. Hence, percutaneous endoscopic lumbar discectomy could be used as an alternative to the conventional procedure in the treatment of recurrent lumbar disc herniation. Search terms were provided, but a full search strategy was not reported, therefore it was not possible to judge if all relevant studies had been retrieved. Further high-quality randomised controlled trials were required to address the present review question.
