Kim HS, et al. - The retrospective case series investigated the early clinical and radiological outcomes of standalone contralateral foraminotomy and lateral recess decompression using percutaneous endoscopic contralateral interlaminar lumbar foraminotomy (PECILF). For treatment of lateral recess and foraminal stenosis, facet preserving contralateral foraminotomy and lateral recess decompression with PECILF proved effective. The contralateral endoscopic approach may result in thorough decompression with acceptable early clinical outcomes and minimal perioperative morbidity.
