Case series of unilateral double-channel endoscope-assisted bone graft fusion and internal fixation in the treatment of recurrent lumbar disc herniation / 西安交通大学学报(医学版)

ABSTRACT

【Objective】 To explore the clinical effect of unilateral double-channel endoscope-assisted bone graft fusion and internal fixation (ULIF) in the treatment of recurrent lumbar disc herniation. 【Methods】 The clinical data of 22 patients with recurrent lumbar disc herniation treated by ULIF in our hospital from August 2020 to October 2020 were analyzed retrospectively. The study indicators included intraoperative blood loss, operation time, bed rest time, and hospital stay. The follow-up data included visual analogue score (VAS) of low back pain, Japanese Orthopaedic Association score (JOA), OSwestry disability index (ODI) score, as well as 36 concise health status survey (SF-36) scores before operation, and 1 week and 6 months after operation. 【Results】 The average operation time was (179.15±42.06) minutes, the average intraoperative blood loss was (132.67±41.92) mL, the average bed rest time was (1.51±0.42) days, and the average hospital stay was (4.82±1.13) days. The VAS score of low back pain at 1 week after operation was lower than that before operation (all P<0.000 1), and further decreased during the follow-up. The ODI score, JOA score and SF-36 score of postoperative follow-up were significantly different from those before operation (P<0.05). The satisfaction rate was 86.4% at 1 week after operation and 95.4% at 6 months after operation. The proportion of significant clinical efficacy at 1 week after operation and postoperative 6 months was 18.2% and 63.6%, respectively. 【Conclusion】 ULIF has the advantages of short-term recovery, less intraoperative blood loss, short bed rest and hospital stay, and good medium-term clinical effect. It is a safe and reliable minimally invasive technique for spinal surgeons in the treatment of recurrent lumbar disc herniation.
