ABSTRACT
STUDY DESIGN:
A prospective, non-randomized studyOBJECTIVES:
To evaluate the early clinical results of percutaneous endoscopic lumbar discectomy (PELD) and microdiscectomy (MD) using a tubular retractor. SUMMARY OF THE LITERATURE REVIEW There are few reports comparing the clinical results of different minimal invasive surgical procedures for disc herniation. MATERIALS ANDMETHODS:
Out of 41 patients who underwent a discectomy at the L4-5 level, 16 patients (Group I) underwent PELD and 25 patients (Group II) underwent MD. The surgical techniques were based on the patient's selection. The characteristics of the operation(operation time, time for C-arm, amount of removed disc) were compared with the clinical outcomes by evaluating the SLR (straight leg raising test), leg VAS (visual analogue scale), ODI (Oswestry Disability Index), hospital day, changes in disc height.RESULTS:
Group I showed a larger amount of disc removed and exposure time for the C-arm than group II (p<0.05). However, the hospital day was shorter in group I than in group II (p<0.05). There were no differences in the leg VAS, ODI, the change in disc height and surgery time between the two groups at the last follow up. One case in group I had a neuropraxia of the L5 root that had recovered fully at postoperative 3months. In group II, there was one case of a postoperative hematoma and 2 cases of a dural tear.CONCLUSION:
Although the early clinical outcomes were similar in both groups, group I showed a larger amount of disc removed and more exposure time to radiation but a shorter hospital stay.
