Background:
Lumbar spinal canal stenosis is a common degenerative pathology, particularly in elderly patients, and often requires surgical treatment when conservative therapy is ineffective. In Armenia, endoscopic decompression using the EasyGo system has not previously been reported.
Objective:
To evaluate the feasibility, safety, and effectiveness of EasyGo-type interlaminar endoscopic decompression for lumbar spinal canal stenosis.
Materials And Methods:
Forty-one patients underwent surgery at the Neurosurgical Department of Nairi Medical Center. Indications included persistent pain syndrome and/or sensory-motor deficits with radiologically confirmed lumbar stenosis. Pain intensity was assessed pre- and postoperatively using a validated questionnaire. Outcomes were graded as good, satisfactory, or unchanged. Operative time, complications, and hospital stay were also recorded.
Results:
Pain intensity decreased by 80-90% on the first postoperative day in 40 patients (97.5%). Sensory symptoms improved by 30-50%. Treatment outcomes were assessed as good in 73.2%, satisfactory in 24.3%, and unchanged in 2.5% (due to diabetic neuropathy). Intraoperative complications included epidural bleeding (2.4%) and dural tears (4.8%), both without clinical consequences. Mean operative time was 40-50 minutes (single level) and 80-90 minutes (two-level/bilateral). All patients ambulated within 6-8 hours and were discharged the following day. No postoperative instability was observed at 2-month follow-up.
Conclusion:
EasyGo-type interlaminar endoscopic decompression is a novel and effective technique in Armenian neurosurgery. It provides significant pain relief, shorter operative time, minimal invasiveness, and one-day hospitalization. Compared to transforaminal endoscopy and open surgery, it allows safer decompression, including contralateral and multilevel cases, with fewer complications. Wider application is warranted for both lumbar and cervical spine pathologies.
