Purpose:We report a case of successful full-endoscopic trans-Kambin triangle lumbar interbody fusion (FE-KLIF) and percutaneous pedicle screw (PPS) fixation performed under local anesthesia (LA) with deep sedation (DS) in an elderly patient with lumbar spondylolisthesis and spinal canal stenosis. Basic procedures:A 93-year-old woman presented with predominantly right-sided bilateral leg pain and distal weakness in the right lower limb. She had undergone posterior decompression five years earlier at another hospital without symptom relief and was referred to our institution. One month later, FE-KLIF and PPS fixation was performed as a second-stage procedure under LA with DS. Main findings:The operation time was 105 min with blood loss of 30 mL. A total of 50 mL of 0.5% lidocaine was used. Sedation was maintained without endotracheal intubation under the supervision of an anesthesiologist. The patient remained breathing spontaneously without intraoperative awakening or complaints of pain. Principal conclusions:FE-KLIF and PPS fixation were performed safely at a single level under LA with DS in a super-elderly patient while maintaining spontaneous respiration with no intubation. No complications associated with general anesthesia were observed such as delirium or pneumonia. J. Med. Invest. 73 : 542-547, August, 2026
