A study on the factors related to postoperative recurrence of lumbar disc herniation treated with percutaneous transforaminal endoscopic discectomy
Objective To analyze the risk factors for postoperative recurrence of lumbar disc herniation(LDH)treated with percutaneous transforaminal endoscopic discectomy.Methods A total of 290 patients with lumbar disc herniation admitted to Guangxi Orthopaedic Hospital from January 2018 to January 2021 were selected as the subjects and received percutaneous transforaminal endoscopic discectomy(PTED).The patients were followed up for at least one year after surgery.Binary logistic regression was used to analyze the risk factors related to postoperative recurrence.Results Among the 290 postoperative patients,16(5.52％)experienced recurrence,while 274(94.48％)did not.There was no statistically significant difference between the two groups in terms of age,gender,drinking history,and segment of lumbar disc herniation(P＞0.05).There were statistically significant differences between the two groups in terms of job nature,outstanding type,body mass index,postoperative activity intensity score,smoking history,and postoperative functional exercise time(P＜0.05).Logistic analysis showed that job nature is heavy physical labor(OR=2.810),body mass index ≥ 24 kg/m2(OR=4.620),smoking history(OR=5.896),type of lumbar disc herniation is the type of protrusion(OR=5.064),functional exercise time＜3 months(OR=4.731),and postoperative activity intensity score≥3(OR=4.107)were all related risk factors for postoperative recurrence(P＜0.05).Conclusion The postoperative recurrence of patients with lumbar disc herniation treated with percutaneous transforaminal endoscopic discectomy was related to job nature s heavy physical labor,body mass index ≥ 24 kg/m2,smoking history,type of lumbar disc herniation is the type of protrusion,functional exercise time＜3 months,and postoperative activity intensity score ≥ 3 points.Clinicians can develop effective measures based on relevant risk factors to reduce the postoperative recurrence rate and avoid secondary surgery.
