To explore the feasibility and
efficiency of percutaneous endoscopic lumbar discectomy (PELD) for
treatment of double-segment lumbar disc herniation through a single
A retrospective study was conducted
on 27 patients who underwent PELD through a single incision for
treatment of double-segment lumbar disc herniation from March 2010 to
March 2016 in our hospital. The visual analogue scale (VAS) , Oswestry
Disability Index (ODI) and modified MacNab criteria were used to
evaluate the outcomes.
All the patients
underwent operation successfully with operation time of 95 min on
average (75~135 min) , blood loss of 20 ml (15~25 ml) and hospital stay
of 6 days (3~14 days) . All the patients were followed up for an average
of 26 months (9~60 months) . The VAS significantly decreased from
(9.00±0.35) preoperatively to (3.15±1.25) at discharge, (2.51±1.67) at
1month after surgery and (1.41±0.33) at the latest follow-up (P<0.05)
. Likewise, the ODI statistically reduced from (71.21±15.22)
preoperatively to (29.46±9.23) at discharged, (17.58±7.16) at 1 month
postoperatively and (10.13±5.29) at the latest follow-up (P<0.05) .
In term of modified MacNab criteria, the clinical results graded as
excellent in 18 patients, good in 6, fair in 1 and poor in 2, with
satisfactory rate of 88.9%(24/27) .
Percutaneous endoscopic lumbar discectomy through a single incision is feasible and safe technique for treatment of double-segment lumbar disc herniation with sound clinical consequences, which should be performed by experienced surgeon, however take advantages of minimized trauma, reduced complications and improved postoperative recovery.
