Abstract:
Objective:To evaluate the clinical effect of percutaneous endoscopic lumbar discectomy (PELD) in the treatment of complex lumbar disc herniation (LDH).Methods:A retrospective analysis of clinical data of 122 patients with LDH who underwent PELD from October 2015 to June 2019 in department of orthopedics, Beijing Chui Yang Liu Hospital was performed. There were 71 males and 51 females. According to whether lumbar disc herniation was a simple non migrated type, the patients were divided into control group ( n=85) and complex group ( n=37). The age, length of stay, operative approach, operation time, the bleeding volume, operative segments, perioperative complications, and excellent and good rate of 3 months after operation were recorded. Follow-up visit was performed by regular outpatient visit for 3 to 36 months. Before and after surgery, 3 days, 1 month, and 3 months after surgery, the Oswestry disability index (ODI) and modified MacNab criteria were used to evaluate the effect of surgery. The measurement data were expressed as mean±standard deviation ( Mean± SD), and the comparison between groups was performed by ANOVA analysis, the count data were expressed as percentage (%), and the comparison between groups was performed by χ2 test or Fisher test, the rank grouping data were performed by Mann-Whitney U non-parametric test. Results:The age of patients in complex group [(63.0±15.9) years] was older than that in control group [(48.7±16.3 years] ( t=2.289, P=0.030), and the length of stay in complex group [(13.0±6.9) d] was longer than that in control group [(8.2±4.3) d] ( t=2.384, P=0.024). There were no significant differences of the operative approach between the two groups ( χ2=0.420, P=0.517). Compared with the control group [(59.0±25.0) min, (16.3±10.9) mL], the operation time of the complex group [(87.0±29.2) min] was longer ( t=2.737, P=0.011), and the bleeding volume [(63.5±52.5) mL] was more ( t=3.925, P=0.001). There were no significant differences of the operative segments between the two groups ( χ2=0.356, P=0.837). The incidence of operation related complications in the complex group (13.5%, 5/37) was significantly higher than that in the control group (2.4%, 2/85) ( χ2=5.937, P=0.026). There were no significant differences in the excellent and good rate between the two groups at 3 months after operation ( U = 1 398.000, P=0.106). The preoperative ODI score of the complex group [(86.6±8.8) scores] was significantly higher than that in the control group [(76.1±7.7) scores]( t=3.359, P=0.002). The ODI score of the two groups decreased significantly. There were significant differences ( t=18.683, P=0.001) between the preoperative [(76.1±7.7) scores] and 3 d postoperative [(36.6±7.5) scores] in the control group. There were significant differences ( t=7.365, P=0.001) between the 3 d postoperative [(36.6±7.5) scores] and 1 month postoperative [(15.0±10.8) scores] in the control group. There were significant differences ( t=4.524, P=0.001) between the 1 month postoperative [(15.0±10.8) scores] and 3 month postoperative [(10.4±12.7) scores] in the control group. There were significant differences ( t=9.923, P=0.001) between the preoperative [(86.6±8.8) scores] and 3d postoperative [(40.1±11.0) scores] in the complex group. There were significant differences ( t=3.619, P=0.006) between the 3d postoperative [(40.1±11.0) scores] and 1 month postoperative [(18.2±15.1) scores] in the complex group. There were significant differences ( t=5.966, P=0.001) between the 1 month postoperative [(18.2±15.1) scores] and 3 month postoperative [(12.7±14.5) scores] in the complex group. Conclusions:PELD technology can treat complex LDH. Compared with simple non migrated LDH, although the operation time is longer, the amount of intraoperative bleeding is more and the incidence of postoperative complications is higher, there is no difference in ODI scores, excellent and good rate. The clinical effect is similar to that of simple non migrated LDH.
