Analysis of risk factors for recurrence after unilateral biportal endoscopy in patients with lumbar disc herniation / 中国内镜杂志

ABSTRACT

Objective To explore the risk factors for recurrence after unilateral biportal endoscopy in patients with lumbar disc herniation.Methods Clinical data of 156 patients with lumbar disc herniation were retrospectively analyzed.All the patients underwent unilateral biportal endoscopy treatment.Follow up for 2 years after surgery,and the recurrence rate of all patients was recorded.The clinical characteristics of patients in the recurrent and non recurrent groups were compared,the factors influencing postoperative recurrence were analyzed by multivariate Logistic regression.Results After a 2-year follow-up,a total of 22 patients experienced recurrence,with a recurrence rate of 14.10%(22/156).The results of multivariate Logistic analysis showed that,the age>60 years old,fiber ring break>5 mm,incomplete nucleus pulposus removal,and postoperative intervertebral motion>10 ° were independent risk factors for recurrence after unilateral biportal endoscopy in patients with lumbar disc herniation(P<0.05).Conclusion Age>60 years old,fiber ring break>5 mm,incomplete removal of the nucleus pulposus,and postoperative intervertebral motion>10 ° were independent risk factors for recurrence after unilateral biportal endoscopy in patients with lumbar disc herniation,and prevention should be strengthened.
