We report excellent outcomes in two patients with cystic lesions in the lumbar spinal canal who underwent resection using the METRx micro-endoscopic discectomy (MED) system. Pathological examinations revealed the diagnoses of a synovial cyst and a discal cyst, respectively. Both of them were allowed to walk the next day after surgery with complete pain relief. Micro-endoscopic surgery provides excellent visualization of the spinal canal and allows minimally invasive removal of the pathological lesions. This technique can be an effective alternative to conventional open surgery for cystic lesions in the lumbar spine.
我们报告了两例腰椎管囊性病变患者，他们使用METRx微型内窥镜椎间盘切除术（MED）系统进行了切除，结果良好。病理检查分别显示为滑膜囊肿和椎间盘囊肿。两人术后第二天即可行走，疼痛完全缓解。微型内窥镜手术能很好地观察椎管情况，并能微创切除病变组织。对于腰椎囊性病变，该技术可作为传统开放手术的有效替代方法。
