The study compared the surgical outcomes, problems, medical results, and functional outcomes between percutaneous endoscopic lumbar discectomy and traditional open discectomy in the therapy of lumbar disc herniation. This non-randomized study was conducted on patients who participated in at the Al-Azhar University Hospitals' Neurosurgery Department between September 2019 and September 2020. For six months after surgery, follow-up was carried out. In the investigation, two distinct groups of 70 consecutive individuals with lumber disc prolapse were found. Group 1: This consists of 35 patients who had percutaneous endoscopic lumbar discectomy (PELD) applying the Destandau procedure with the Endospine Karl Storz system. Group 2: Those who received a COD (conventional open discectomy). Both approaches provide positive outcomes for patients, while each method has certain benefits over the other. The benefits of endoscopic discectomy include a smaller cut, less intraoperative bleeding, and a shorter hospital stay owing to reduced discomfort from the injury. In contrast, a traditional open discectomy results in a bigger lesion with improved visibility and equipment mobility, making it simpler to identify and handle any complications. Endoscopic discectomy has a more steep learning curve than open surgery, therefore it takes doctors longer to become proficient. As a result, attention must be made to identify the optimal surgical approach for each patient, which must be most suitable for the patient and proficient in by the surgeon.
