Abstract:
Objective:To analyze the perioperative data of patients with lumbar spinal stenosis who were surgically treated by unilateral biportal endoscopy-unilateral laminectomy for bilateral decompression (UBE-ULBD) technique, and to explore the occurrence, clinical features, and influencing factors for perioperative complications.Methods:A retrospective analysis of the clinical data of 77 patients with lumbar spinal stenosis who underwent UBE-ULBD surgery in the Department of Orthopedics, Beijing Friendship Hospital, Capital Medical University from June 2021 to June 2023 was performed, of which 28 were males and 49 were females, with a mean age of (67.61±15.29) years. The baseline data, surgery-related information, and complications and subjective scores during the perioperative and follow-up periods of the patients were collected. Continuous variables were tested for normality using the Kolmogorov-Smirnov test. Normally distributed continuous variables were expressed as mean ± standard deviation ( ± s), and the Student- t test and analysis of variance for repeated measures information were used for comparison between groups; non-normally distributed continuous variables were expressed as median (interquartile distance) [ M( Q1, Q3)], and and non-parametric tests were used for comparison between groups. Categorical variables were expressed as number of cases and percentage, and the Chi-square test was used for comparison between groups. Variables were analyzed using univariate analysis, and indicators with statistically significant differences in the results of univariate analysis were further included in multivariate Logistic regression analysis to further clarify the independent risk factors for the occurrence of complications. Results:According to the occurrence of postoperative complications, the patients were divided into the non-complication group ( n=73) and the complication group ( n=4). The complication group included 2 cases of dural tear, 1 case of postoperative residual symptoms, and 1 case of postoperative epidural hematoma. Compared with the preoperative results, the Oswestry disability index (ODI) score and visual analogue score (VAS) for low back pain and leg pain on the first day after surgery were improved, and the differences were statistically significant ( P<0.01). Compared with the first day after surgery, except for the ODI scores, the VAS scores for low back pain and leg pain were improved at the third month after surgery, and the differences were statistically significant ( P< 0.01). The differences in intraoperative blood loss and operative time between the two groups were statistically significant ( P<0.05). The variables with statistically significant differences in univariate analysis were included in the multivariate Logistic regression analysis, and the results indicated that prolonged operative time was an independent risk factor for perioperative complications in patients ( OR=1.031, 95% CI: 1.000-1.054, P=0.030). Conclusions:As an effective minimally invasive spinal endoscopic technique for the treatment of lumbar spinal stenosis, the UBE-ULBD technique has the advantages of lower complication rates and faster postoperative recovery. Improvement of surgical proficiency by the operator and appropriate shortening of operative time can help to reduce the incidence of complications such as dural tear.
