CMConor McNameeUniversity College Dublin DKDavid KellyUniversity College Dublin OSOisin ShannonUniversity College Dublin

Key Points

This review aims to evaluate the long-term outcomes of primary percutaneous endoscopic lumbar discectomy (PELDE).
Conducted a systematic review and meta-analysis of available literature on PELD.
Focused on outcomes including symptom relief, complications, recurrence, and reoperations.
Analyzed predominantly retrospective data with noted limitations.
PELDE demonstrated sustained symptom relief over a long-term follow-up period.
Reported low rates of complications, recurrence, and reoperation.
Late clinical and functional outcomes were generally favorable despite limitations from data quality.

Abstract

PELD may provide sustained symptom relief and low rates of complication, recurrence, and reoperation in long-term follow-up. Late clinical and functional outcomes appear to be favorable. However, the predominance of retrospective data and selective loss to follow-up limits the strength of the conclusions.
