Complications of endoscopic lumbar decompression surgery

Area of Science:

• Minimally Invasive Spine Surgery
• Surgical Education and Training
• Neurosurgery

Background:

• Endoscopic lumbar decompression is increasingly utilized globally for spinal conditions.
• This review examines surgery-related complications and the learning curve associated with this minimally invasive technique.
• Understanding complication rates is crucial for patient safety and procedural refinement.

Purpose of the Study:

• To evaluate the incidence of surgery-related complications in endoscopic posterior decompression.
• To analyze the learning curve by comparing complication rates between early and late surgical periods.
• To identify specific conditions where the learning curve is most pronounced.

Main Methods:

• A retrospective review of 138 patients undergoing endoscopic posterior decompression from August 2000 to April 2008.
• Patients were categorized by condition: Herniated Nucleus Pulposus (HNP), Lumbar Canal Stenosis (LCS), and others.
• Complication rates were compared between disease types and between an early (E) and late (L) surgical group, defined by a 2003-2005 sabbatical break.

Main Results:

• Overall complication incidence was 8.6% (11 of 138 patients), including dural tears, hematomas, neural issues, and fractures.
• Complication rates for HNP and LCS were 8.1% and 9.3%, respectively.
• The complication rate was significantly higher in the early group (11.3%) compared to the late group (5.3%), with a particularly high rate (16.7%) for LCS in the early group.

Conclusions:

• Endoscopic lumbar decompression demonstrates a steep learning curve.
• Surgeons should acquire proficiency in endoscopic surgery for HNP before undertaking LCS procedures.
• Experience significantly reduces complication rates, highlighting the importance of supervised training and gradual progression.
