Abstract：Objective To evaluate midterm outcomes of microendoscopic discectomy ( MED ) in the treatment of lumbar disc herniation.Methods From December 2010 to December 2013, 73 patients ( 74 discs, 46 males and 27 females ) with lumbar disc herniation received MED. The average age was 45.8 years ( range: 22 - 75 years ). Clinical outcomes were evaluated by the visual analogue score ( VAS ) and MacNab standard.Results All patients completed the follow-up. The mean follow-up was 49.8 months ( range: 36 - 60 months ). VAS scores preoperatively, 3 months postoperatively, 1 year postoperatively and the latest follow-up were ( 6.93 ± 0.86 ) points, ( 1.56 ± 0.83 ) points, ( 1.36 ± 0.74 ) points, and ( 1.26 ± 0.74 ) points. Postoperative VAS scores were signiifcantly lower than those before the surgery (P< 0.01 ). Medium-term follow-up efficacy: MacNab standard, excellent in 55 cases, good in 11 cases, fair in 4 cases, poor in 3 cases, the excellent and good rate was 90.4%. Postoperative recurrence occurred in 3 cases: 1 case received conservative treatment and 2 cases underwent the second stage operation, the recurrence rate was 4.1%. One case with foot drop was not satisifed with the result.Conclusions MED is an effective procedure with good mid-term outcomes in the treatment of lumbar disc herniation. The advantages of the procedure include less tissue trauma, less postoperative complications and early postoperative recovery.
