OBJECT: Lumbar @entity12897 are a potential cause of @entity614 and @entity615 , and the definitive treatment is the complete excision of the cyst. This report summarizes the authors' preliminary clinical experience with the minimally invasive resection of lumbar @entity12897 . METHODS: Nineteen @entity1 (nine @entity1 and 10 @entity1 ) with symptomatic @entity12897 underwent minimally invasive resection. The mean @entity1 age was 64 years of age (range 43-80 years). The presenting symptom was @entity614 in 16 @entity1 , @entity1643 in two, and @entity425 in one. There were 16 cases of a cyst located at the L4-5 level, two at @entity6357 , and one at L5-S1. The mean cyst diameter was 13.7 mm (range 3-30 mm). The mean follow-up time was 16 months (range 4-29 months). Clinical outcomes were graded, based on the Macnab modified criteria, as excellent, good, fair, or poor. Eighteen @entity1 (95% of cases) reported either excellent (10 @entity1 ) or good (eight @entity1 ) results, and a fair result was reported by one @entity1 (5% of cases). The mean operative time was 158 minutes (range 75-270 minutes), and the average intraoperative @entity190 was 31 ml (range 10-100 ml). Two @entity1 had intraoperative dural tears that resulted in @entity5173 that resolved following primary closure. CONCLUSIONS: @entity12897 can be safely and effectively treated using minimally invasive surgical techniques. Long-term follow up is required to determine whether this approach results in less need for fusion than conventional surgical approaches.
