ABSTRACT

Objective

Minimally invasive procedures in spine surgery have undergone significant development in recent times. A demand emerged from both surgeons and patients to develop and perform these types of surgeries in order to prevent biomechanical and surgical complications. Our study aimed to present early clinical results of a biportal endoscopy technique in the treatment of degenerative spinal stenosis.

Method

We created a retrospective database of patients who underwent biportal spinal endoscopic decompression at the National Institute of Clinical Neuroscience, Department of Neurosurgery, Semmelweis University, Budapest, Hungary, in 2019. The surgical steps of technique is discussed in details.

Results

Retrospectively, we identified and collected 21 patients in our retrospective analysis. The early results after endoscopic decompression were excellent, 17 patients (81%) mentioned good general comfort which coincided with small incisions and the preservation of posterior spinal muscles. Three patients (14%) mentioned good condition and minor postoperative pain which could be controlled with analgesics. One patients (5%) mentioned postoperative discomfort. The patients were controlled at 3, 6 and 9 months. The mean follow-up time was 7 months.

Discussion

Biportal endoscopic technique was developed to fulfil the requirements of minimally invasive techniques. Our results indicate this method may be highly effective for the treatment of lumbar spinal stenosis and an alternative to conventional microsurgical decompression; however, our study limited by its retrospective manner and small population size

双孔内窥镜技术治疗椎管狭窄：早期临床经验和结果。

摘要

客观的

近年来，脊柱手术中的微创手术取得了重大进展。外科医生和患者都需要开发和执行这些类型的手术，以防止生物力学和手术并发症。我们的研究旨在展示双门内窥镜技术治疗退行性椎管狭窄的早期临床结果。

方法

我们创建了一个回顾性数据库，其中包含 2019 年在匈牙利布达佩斯 Semmelweis 大学神经外科国家临床神经科学研究所接受双孔脊柱内窥镜减压术的患者的回顾性数据库。详细讨论了手术步骤。

结果

回顾性地，我们在回顾性分析中确定并收集了 21 名患者。内镜下减压术后早期效果良好，17例（81%）患者总体舒适度良好，切口小，保留了脊柱后侧肌肉。3 名患者（14%）表示情况良好，术后疼痛轻微，可用镇痛药控制。一名患者 (5%) 提到术后不适。患者在3、6和9个月时得到控制。平均随访时间为 7 个月。

讨论

双孔内窥镜技术的开发是为了满足微创技术的要求。我们的研究结果表明，这种方法可能对治疗腰椎管狭窄症非常有效，并且可以替代传统的显微手术减压；然而，我们的研究受限于其回顾性方式和较小的人口规模
