Abstract: Objective   This study explored the clinical effect of using transforaminal technique to treat patients with lumbar disc herniation and lateral recess stenosis. Methods   132 patients with lumbar disc herniation and lateral recess stenosis who were treated by orthopedic surgery in our hospital from July 2018 to December 2022 were selected for retrospective analysis.They were divided into the endoscopic group and the traditional group according to the surgical method.70 patients in the endoscopic group were treated by the inter-laminar approach under the technique of intervertebral foramen,and 62 patients in the traditional group were treated by the traditional open surgery.The operation process indexes of the two methods were compared The clinical symptoms of patients after operation were different. Results   The average operation time[（76.1±7.5）min],surgical blood loss[（30.5±8.4）ml],incision length[（0.88±0.12）cm],post-operative drainage[（24.5±4.4）ml],bed time[（26.8±4.4）h],and length of stay[（5.6±1.8）d] in the endoscopic group were significantly lower than those in the traditional group[（88.0±9.3）min,（103.4±18.6）ml,（6.10±1.04）cm,（208.3±34.0）ml,（32.7±6.6）h and （9.4±2.0）d,respectively].The difference was statistically significant (P＜0.05).VAS scores of 3 months and 6 months after surgery were lower than those before surgery, and JOA scores were higher, the difference was statistically significant(P＜0.05).The lumbar function of the endoscopic group was excellent in 43 cases (61.43%) and good in 15 cases (21.43) %),29 cases of lumbar spine function were excellent (46.77%) and 17 cases (21.43%) were good in the traditional group.Overall,there was no statistically significant difference in the recovery of lumbar spine function between the endoscopic group and the traditional group (P >0.05).2 patients(2.86%) in the endoscopy group had postoperative complications,and 7 patients(11.29%) in the traditional group had postoperative complications,but there was no significant statistical difference in the incidence of surgical complications between the two groups (P＞0.05). Conclusion   For the treatment of lumbar disc herniation with lateral recess stenosis under intervertebral foraminal technique,the treatment of lumbar intervertebral disc herniation with lateral recess stenosis can achieve better functional recovery and effectively relieve the clinical symptoms of the patient,but its advantage lies in the operation time.Shorter,less traumatic impact on patients.
