Open discectomy (OD) is the standard operation for lumbar disc herniation (LDH). Percutaneous endoscopic lumbar discectomy (PELD), however, has shown similar outcomes to OD and there is increasing interest in this procedure. However despite improved surgical techniques and instrumentation, reoperation and infection rates continue and are reported to be between 6% and 24% and 0.7% and 16%, respectively. The objective of this study was to compare the rate of reoperation and infection within six months of patients being treated for LDH either by OD or PELD.

经皮内窥镜腰椎间盘切除术和开放式腰椎间盘切除术后再手术和感染的风险：一项全国性的基于人群的研究。

开放式椎间盘切除术（OD）是腰椎间盘突出症（LDH）的标准手术。然而，经皮内窥镜腰椎间盘切除术 (PELD) 已显示出与 OD 相似的结果，并且对该手术越来越感兴趣。然而，尽管手术技术和器械有所改进，但再手术率和感染率仍在继续，据报道分别在 6% 和 24% 以及 0.7% 和 16% 之间。本研究的目的是比较接受 OD 或 PELD 治疗 LDH 的患者六个月内的再手术率和感染率。
