Study on Influencing Factors of Postoperative Recurrence of Lumbar Disc Herniation Treated by Percutaneous Transforaminal Endoscopic Discectomy

To investigate the influencing factors of percutaneous perforation for lumbar disc herniation. A total of 65 patients with recurrent lumbar disc herniation treated in our hospital from January 2015 to December 2020 (observation group) were selected and 130 patients without recurrence were selected as the control group. 65 patients with recurrent lumbar disc herniation were divided into Group A (n=32) and Group B (n=33). The patients in Group A were treated with percutaneous transforaminal endoscopic lumbar discectomy and the patients in Group B were treated with traditional spinal canal decompression, and nucleus pulposus removal cage fusion and internal fixation. The operation, Japanese orthopaedic association score and Oswestry disability index of the two groups were observed. Logistic regression analysis showed that age, body mass index, Pfirrman classification, incomplete removal of nucleus pulposus during operation and postoperative sedentary work or heavy physical work were the influencing factors of postoperative recurrence (Odds ratio=1.667, 1.545, 1.831, 2.038 and 1.925, p<0.05). The operation time, intraoperative blood loss and hospitalization time in Group A were (50.51 +/- 3.39) min, (45.51 +/- 3.15) ml and (12.03 +/- 3.22) d, respectively, which were significantly less than those in Group B (p<0.05). Japanese orthopaedic association score at 3 mo after operation in Group A was (25.51 +/- 2.03) points, which was significantly higher than that in Group B (p<0.05), while Oswestry disability index was (20.03 +/- 2.62) %, which was significantly lower than that in Group B (p<0.05). The visual analogue scale score of Group A at 3 mo after operation was (2.50 +/- 0.44) points, which was significantly lower than that of Group B (p<0.05). Patients with recurrence after percutaneous transforaminal endoscopic treatment effect are still good.
