Efficacy and prognostic factors of percutaneous intervertebral foramen BEIS technique in the treatment of recurrent lumbar disc herniation / 临床外科杂志

ABSTRACT

Objective To evaluate the efficacy of percutaneous endoscopic BEIS technique in the treatment of recurrent lumbar disc herniation and to analyze its possible prognostic factors.Methods A total of 39 patients who are diagnosed as lumbar disc herniation and treated with percutaneous endoscopic BEIS technique were selected from March 2013 to March 2015.The clinical efficacy was evaluated according to VAS,ODI,JOA and modified MacNab criteria in the follow-up,and the possible prognostic factors were analyzed.Results The average follow-up time was 14 months(12 ～ 18 months).According to the MacNab standard,the excellent and good rate was 82.1％.The average score of back and leg pain VSA was reduced from(7.33 ± 1.01)before operation to(2.69 ± 1.50)after operation,t =16.111,the difference was statistically significant (P ＜ 0.05);ODI and JOA were used to evaluate lumbar function,the score of ODI was reduced from (59.08 ± 7.16) to (13.54 ± 3.36),t =35.946,and that of JOA was increased from(14.92 ±3.37) to(26.05 ± 1.76),t =-18.526,the difference was statistically significant (P ＜ 0.05).Patients with symptoms lasting no more than 3 months and with no lateral recess stenosis were able to obtain good therapeutic effect.Conclusion This study indicates that percutaneous endoscopic BEIS technique is effective in the treatment of recurrent lumbar disc herniation,and duration of symptoms and lateral recess stenosis are important prognostic factors.
