Percutaneous endoscopic lumbar discectomy - early clinical experience

Current spinal decompression methods often involve larger incisions and more tissue disruption. While traditional open discectomy remains a standard, newer minimally invasive approaches are being explored. Prior research has shown that percutaneous techniques can reduce recovery times and complications. However, the long-term efficacy of these newer methods remains unclear. No prior work had resolved the exact role of endoscopic approaches in lumbar herniation treatment. That uncertainty drove the need to evaluate percutaneous endoscopic lumbar discectomy (PELD). This gap motivated the study to assess early clinical outcomes of PELD. The study aimed to determine whether PELD could offer a viable alternative to conventional methods.

The aim was to evaluate the early clinical outcomes of percutaneous endoscopic lumbar discectomy (PELD) for treating lumbar herniated nucleus pulposus (HNP). The researchers focused on assessing the safety and effectiveness of PELD in a clinical setting. They introduced PELD in June 2009 and followed patients up to August 2011. The specific problem addressed was the lack of data on PELD's performance compared to traditional methods. The motivation was to determine whether PELD could reduce tissue damage and recovery time. The study sought to document surgical duration, hospital stay, and symptom relief. The goal was to establish whether PELD could be a promising minimally invasive option. The findings were intended to guide future clinical adoption of PELD.

The study involved 311 patients with degenerative lumbar spine disease treated between June 2009 and August 2011. Thirty-seven patients with lumbar HNP underwent PELD. The surgical approach varied: 28 used the transforaminal route, 5 the interlaminar route, and 4 the extraforaminal route. Surgery was performed under local anesthesia with continuous saline irrigation. In three cases, surgery was stopped due to pain or anatomical barriers. The remaining 34 patients had surgery lasting 34 to 103 minutes. Postoperative MRI confirmed HNP removal in all patients. Hospital stays were limited to 1 or 2 days for all patients.

Immediate symptom relief was observed in all 34 patients who completed the procedure. Postoperative MRI showed sufficient HNP removal in all cases. Surgical duration ranged from 34 to 103 minutes with an average of 62.4 minutes. Blood loss was minimal in all patients. Hospital stays were consistently short, lasting 1 or 2 days. Three patients had surgery discontinued due to intraoperative issues. The transforaminal approach was most frequently used among the three methods. The findings suggest PELD offers a minimally invasive alternative with low complication rates.

The authors report that PELD is a promising minimally invasive option for lumbar HNP. The study showed immediate symptom relief and sufficient HNP removal in most cases. The procedure was associated with minimal tissue damage and short hospital stays. The use of local anesthesia and saline irrigation supported the minimally invasive nature of PELD. The authors suggest that PELD differs from percutaneous nucleotomy by directly removing HNP. The findings are based on early clinical experience and limited patient numbers. The authors propose that PELD may offer advantages over traditional methods. The study highlights the potential of PELD as a viable alternative for HNP treatment.
