Comparative Analysis Of Medium-term And Short-term Efficacy Of Microendoscopic Disectomy And Fenestration Discectomy For Lumbar Disc Herniation

Objective:To compare the Medium-term and short-term efficacy, advantages and disadvantages of the mono-segment lateral lumbar disc herniated patients with the treatment of microendoscopic discectomy and fenestration discectomy.Methods:476 cases operated with mono-segment discectomy were analyzed from January 2001 to December 2005, among them, 215 cases operated with microendoscopic discectomy and 261 cases operated with fenestration discectomy.Were randomly selected 50 cases in two group, the length of surgical incision, the operating time, blood loss, the average temperature for three days after surgery, time stay-in-bed, duration of hospitalization after operation, preoperative and postoperative JOA score, low back pain and leg pain VAS score were compared.Results:The rate of excellent and good outcomeswas 98% in MED group, and 96% in fenestration discectomy group, no significant difference was found between them, and the same with the postoperative sciatica relief.Significant differences ould be observed in the postoperative Low back pain VAS score, the length of surgical incision, blood loss, time stay-in-bed and duration of hospitalization after operation.Conclusion:The symptoms of the lumbardisc herniation can be reliefed effectively by both methods, but microendoscopic discectomy has more advantages of less trauma, less bloodloss, earlier rehabilitation, less postoperative low back pain, but relatively narrow operative indication, still not a perfect substitute for fenestration discectomy.
