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

双端口内窥镜技术治疗脊柱狭窄的早期临床经验和结果

目的

脊柱外科手术中的微创手术近来已取得重大进展。为了防止生物力学和外科手术并发症，外科医生和患者都出现了开发和执行这类手术的需求。我们的研究旨在提出双门内镜技术在退行性脊柱狭窄治疗中的早期临床结果。

方法

我们于2019年在匈牙利布达佩斯的Semmelweis大学神经外科学系的国家临床神经科学研究所创建了接受双门脊柱内镜减压术的患者的回顾性数据库。将详细讨论技术的手术步骤。

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。内窥镜减压术后的早期结果非常好，有17例患者（81％）提到良好的总体舒适度，同时切口较小并保留了脊柱后肌。三名患者（14％）提到病情良好，术后疼痛轻微，可以用止痛药控制。1例（5％）提到术后不适。将患者控制在3、6和9个月。平均随访时间为7个月。

讨论区

双向内窥镜技术的发展是为了满足微创技术的要求。我们的结果表明，该方法对于治疗腰椎管狭窄症可能是非常有效的方法，并且可以替代传统的显微外科减压术。然而，我们的研究受到回顾性研究和人口少的限制
