Abstract：Objective To investigate the surgical techniques and clinical effects of percutaneous endoscopic interlaminar discectomy ( PEID ) in the treatment of prolapsed and sequestrated L5-S1 lumbar disc herniation. Methods A total of 94 patients with L5-S1 prolapsed and sequestrated lumbar disc herniation were treated by PEID from January 2010 to June 2012. There were 53 males and 41 females, whose average age was 29.69 years old ( range:13-56 years ). The Visual Analogue Scale ( VAS ), Oswestry Disability Index ( ODI ) and modiifed MacNab criteria were used for the evaluation of clinical effects. Results All the patients were followed up for a mean period of 26.5 months ( range:12-37 months ). The mean operation time was ( 66.4±8.4 ) min. The average intraoperative fluoroscopy time was ( 0.5±0.2 ) s. Sensory disturbance, muscle weakness and low back and leg pain were alleviated in different degrees after the operation in all the patients. The VAS scores of low back pain were ( 5.40±1.12 ), ( 3.36±0.96 ), ( 1.86±0.99 ), ( 1.18±0.83 ), ( 0.78±0.62 ) and ( 0.58±0.64 ) point preoperatively and at 1 day, 1 month, 3 months, 6 months and 12 months after the operation. The VAS scores of leg pain was ( 8.40±0.95 ), ( 2.66±1.53 ), ( 1.98±1.00 ), ( 1.20±0.81 ), ( 0.82±0.66 ) and ( 0.68±0.62 ) point in the corresponding follow-up time. The ODI scores were 51.88±8.88, 33.22±10.33, 23.46±7.47, 15.10±5.72 and 10.38±5.93 preoperatively and at 1 month, 3 months, 6 months and 12 months after the operation. Statistically signiifcant differences existed in the VAS scores and ODI scores of low back and leg pain preoperatively and in the corresponding follow-up time ( P<0.01 ). The excellent and good rate was 94.7%in the latest follow-up according to the modiifed MacNab criteria. Conclusions PEID is a safe, effective and minimally invasive procedure in the treatment of prolapsed and sequestrated L5-S1 lumbar disc herniation, with the advantages of less trauma, less blood loss, less intraoperative lfuoroscopy and quick recovery. Its short-term results are satisfactory, while its long-term outcomes require further follow-ups.
