Endoscopic Treatment of Lumbar Arachnoiditis

Abstract

Objective: The diagnosis of lumbar arachnoiditis remains complex and often inconclusive. Using the technique of lumbar subarachnoidal endoscopy (thecaloscopy), the pathology can be identified and the patient treated with long-term effects on the symptoms.

Method: Endoscopic operations were performed on 23 patients suffering from varying symptoms with an enlarged lumbar subarachnoidal space. Having confirmed the diagnosis of lumbar arachnoiditis, a number of endoscopic operations ranging from adhesiolysis to subarachno-epidurostomy were carried out.

Results: Radicular symptoms in lumbar arachnoiditis were successfully relieved by various endoscopic dissection techniques, such as restoration of the improved CSF flow by subarachno-epidurostomy along the rootlet. This has been identified as one of the causal factors of the clinical symptoms. In cases where lumbar pain persists in spite of a previous thecaloscopy, further treatment with a lumboperitoneal shunt device has proved most successful.
