Removal of discal cyst using percutaneous full endoscopic via interlaminar route: a case report

Abstract Background Discal cyst, a rare disease with unclear pathogenesis, exhibits symptoms similar to lumbar disk herniation. Currently, there is no consensus on the optimal treatment for this condition. Case presentation This report presents the clinical efficacy of the percutaneous endoscopic interlaminar approach surgery technique in patients diagnosed with lumbar 4–5 discal cyst. The patient exhibited sub-acute radiculopathy in the left leg accompanied by weakness of the extensor hallucis longus. Magnetic resonance imaging of the lumbar spine confirmed the presence of lumbar discal cysts, which exerted compression on the traversing nerve root. Surgical treatment involved performing percutaneous endoscopic interlaminar approach surgery without additional discectomy under general anesthesia. The symptoms were immediately alleviated following the removal of the discal cysts, and the weakness in the toe improved the day after the surgery. No recurrent symptoms or complications were observed during the 6-month follow-up period. Conclusion Based on our findings, we posit that percutaneous interlaminar endoscopic surgery represents a safe, minimally invasive, and appropriate approach for treating discal cysts.
