OBJECTIVE: The objectives of this study were to determine the frequency of symptomatic @entity9007 ( @entity9007 ) after endoscopic discectomy and to compare the results of surgical and conservative management of them. METHODS: Initial study @entity1 were 1,503 cases (1,406 @entity1 ) receiving @entity2649 by 23-member board of neurosurgeons from March 2003 to October 2008. All @entity1 ' postoperative magnetic resonance imaging (MRI) scans were evaluated. On the postoperative MRI, cystic lesion of T2W high and T1W low at discectomy site was regarded as @entity9007 . Reviews of medical records and radiological findings were done. The @entity9007 @entity1 were divided into two groups, surgical and conservative management by treatment modality after @entity9007 detection. We compared the results of the two groups using the visual analogue scale (VAS) for @entity1643 ( @entity1643 ), VAS for @entity158 ( @entity158 ) and the @entity717 index (ODI). RESULTS: Among 1,503 cases of all male soldiers, the MRIs showed that @entity9007 formed in 15 @entity1 , about 1.0% of the initial cases. The mean postoperative interval from surgery to @entity9007 detection was 53.7 days. Interlaminar approach was correlated with @entity9007 formation compared with transforaminal approach (p=0.001). The mean VAS for @entity1643 and @entity158 in the surgical group improved from 6.5 and 4.8 to 2.0 and 2.3, respectively. The mean VAS for @entity1643 and @entity158 in the conservative group improved from 4.4 and 4.4 to 3.9 and 2.3, respectively. There was no difference in treatment outcome between surgical and conservative management of symptomatic @entity9007 . CONCLUSION: Although this study was done in limited environment, symptomatic @entity9007 was detected at two months' postoperative period in about 1% of cases. Interlaminar approach seems to be more related with @entity9007 compared with transforaminal approach.
