Evaluation on curative effects of percutaneous endoscopic lumbar discectomy via a transforaminal approach versus an interlaminar approach for patients with lumbar disc herniation: A protocol for systematic review and meta-analysis.

Abstract

Background:The present meta-analysis aims to conduct a systematic comparative study of the curative effects of Percutaneous Endoscopic Transforaminal Discectomy (PETD) and Percutaneous Endoscopic Interlaminar Discectomy (PEID) when used to treat Lumbar Disc Herniation (LDH).Methods:The following online databases will be searched to find articles related to treating of LDH using PETD and PEID, namely PubMed, EMBASE, Cochrane databases, China National Knowledge Infrastructure, WanFang Database, and Web of Science. The search will include all articles published from inception until August 2021. Articles will be included according to the inclusion criteria. Two authors will independently screen and assess the quality of each study. RevMan (version 5.3) will be adopted to complete data analysis and evaluate the statistical significance of each operating technique in various outcomes.Results:The present meta-analysis will evaluate the curative effects of using PETD and PEID to treat LDH patients.Conclusion:Compare the clinical efficiency of PETD and PEID as therapy for LDH with postoperative hypoesthesia, complications in surgical site wounds, nerve root injury, transfer to open surgery, recurrence, partial decompression, and other complications. The comparative analysis will help determine the difference between the 2 surgical methods of PETD and PEID for treating LDH.OSF registration number:August 2, 2021.osf.io/hr964.
