Endoscopic Lumbar Discectomy

Background: Percutaneous endoscopic lumbar discectomy (PELD) is one of the most sophisticated operative procedures for the treatment of lumbar disc herniation (LDH). Endoscopic techniques are now becoming standard in many areas due to expanded technical possibilities of full-endoscopic transforaminal or interlaminar resection of herniated lumbar discs as well as stenosis. However conventional percutaneous endoscopic interlaminar discectomy (PEID) disc operations may sometimes result in subsequent untoward complications due to unnoticed iatrogenic trauma to neural structures, which is mostly related to an anatomical limitation during endoscope insertion.Methods: An appropriate operative indication of the PEID without bone removal or laminectomy can be used to treat LDH cases with an enough interlaminar space (at least ≥ 20 mm by bi-facetal distance) from the reported evidences. Otherwise, there might be several indications for requirement of bone removal; a narrow interlaminar space, disappearance of the concave shape of the upper vertebral laminae, high-grade migration of LDH, recurrent LDH, obesity, or an immobile nerve root.Conclusion: The significance of PEID lies also in its minimal damage to surrounding structures such as muscle, bone, and ligaments. A discrete radiographic evaluation from the patient preoperatively is mandatory before choosing a proper endoscopic surgical modality for the sake of optimal clinical outcome after PEID.

Common Procedure

Summary Lumbar disc herniation (LDH) is the most common pathology in young people, as well as people of active age. Despite sophisticated and new minimally invasive surgical techniques and approaches, reoperations for recurrent lumbar disc herniation (rLDH) could not be avoided. LDH recurrence rates, reported in different studies, range from 5 to 25%. The purpose of this study was to estimate the recurrence rates of LDH after standard discectomy (SD) and microdiscectomy (MD), and compare them to those reported in the literature. Retrospectively, operative reports for the period 2012-2017 were reviewed on LDH surgeries performed at the Neurosurgery Clinic of Dr Georgi Stranski University Hospital in Pleven. Five hundred eighty-nine single-level lumbar discectomies were performed by one neurosurgeon. The diagnoses of recurrent disc herniation were based on the development of new symptoms and magnetic resonance/computed tomography (MRI/CT) images showing compatible lesions in the same lumbar level as the primary lumbar discectomies. The recurrence rate was determined by using chi-square tests and directional measures. SD was the most common procedure (498 patients) followed by MD (91 patients). The cumulative reoperation rate for rLDH was 7.5%. From a total number of reoperations, 26 were males (59.1%) and 18 were females (40.9%). Reoperation rates were 7.6% and 6.6% after SD and MD respectively. The recurrence rate was not significantly higher for SD. Our recurrence rate was 7.5%, which makes it comparable with the rates of 5-25% reported in the literature.
