BACKGROUND: Discal cyst is a rare pathology causing lumbar radiculopathy. Conventional open and microsurgical resection is the most commonly reported surgical treatment for discal cyst. Full-endoscopic surgeries are an efficient but sparsely reported modality.

CASE PRESENTATION: This is a retrospective study that presents the outcomes of 2 patients with lumbar discal cyst (with radiculopathy in the legs and Visual Analog Scale (VAS) scores of 10 out of 10, classic clinical-radiological presentation features) who were treated with Percutaneous transforaminal endoscopic lumbar discectomy (PTELD) under local anesthesia (LA). Validated Oswestry Disability Index (ODI) and MacNab scores were used for clinical outcome assessment. Additionally, we conducted a review of the literature on full-endoscopic approaches for discal cyst, namely PTELD, percutaneous interlaminar endoscopic lumbar discectomy (PIELD), and transsacral epiduroscopic decompression (SELD).

CONCLUSION: PTELD for lumbar discal cyst is an excellent method to yield a positive long-term out-come, and one of the most minimally invasive full-endoscopic approaches.
