[Decompression of lumbar lateral spinal stenosis: full-endoscopic, interlaminar technique].

OBJECTIVE: Decompression in lumbar recess stenosis in a full-endoscopic technique using an interlaminar approach. INDICATIONS: Lumbar recess stenosis due to ligamentous, osseous, discogenic compression, and/or juxta-facet cysts. CONTRAINDICATIONS: Pure back pain, instability/deformity requiring correction, pure foraminal stenosis. SURGICAL TECHNIQUE: Introduction of a surgical sleeve to the intralaminar window. Endoscopic resection of compressing bony/ligamentary structures and also of osteophytes or parts of annulus. POSTOPERATIVE MANAGEMENT: Immediate mobilization, isometric/coordination exercises, functional exercises from week 3, building up strength from week 6.
RESULTS: A total of 192 patients underwent full-endoscopic surgery or microsurgery and were followed up over a minimum of 2 years. A significant improvement was revealed. Serious complications occurred in 5% and were significantly reduced in the endoscopic group. Five patients were revised with decompression and/or fusion. Eighty-nine percent would undergo the operation again.
