- Abstract: Objective To investigate the effect of different decompression methods on the efficacy of the unilateral biportal endoscopy(UBE)in the treatment of severe lumbar spinal stenosis(LSS).Methods A total of 203 elderly patients with LSS who underwent UBE treatment in our hospital from September 2021 to June 2024 were selected and divided into the unilateral group(102 cases)and the bilateral group(101 cases)according to different decompression methods.The unilateral group underwent unilateral decompression during operation,while the bilateral group underwent bilateral decompression(with bilateral decompression through the same incision and unilateral approach)during operation.The perioperative conditions,anatomical image parameters,visual analogue scale(VAS)scores,Oswestry disability index(ODI),and complications were compared between the two groups.The rehabilitation progress and complications of patients with different Charlson comorbidity index(CCI)values were compared.Results The operation time of patients in the bilateral group was longer than that in the unilateral group(P<0.05).The dural sac area and lumbar spinal canal area of patients in the bilateral group were larger than those in the unilateral group immediately after operation and 3 months after operation(P<0.05).The VAS scores and ODI 7 days and 3 months after operation of patients in the bilateral group were lower than those in the unilateral group(P<0.05).There was no statistically significant difference in the total incidence of complications between the two groups of patients(P>0.05).The first time of getting out of bed after operation and hospital stay in patients with CCI value>2 scores were longer than those in patients with CCI value≤2 scores(P<0.05).Conclusion Compared with unilateral decompression,bilateral decompression for elderly patients with severe LSS takes a longer surgical time,but it can better restore lumbar shape,alleviate pain,improve lumbar function,and has higher safety,and the milder the patient's condition,the faster the postoperative recovery.
