two-stage operation for resection of XXXX : technical case report of three cases.

@entity1 @entity5 @entity16 @entity602 @entity51 @entity816 @entity4097 @entity736
OBJECTIVE AND IMPORTANCE: Surgery for excision of intramedullary @entity4097 without increasing @entity51 is one of the more difficult operations in spinal surgery. In particular, infiltrating @entity816 without a clear cleavage between the @entity5 and normal spinal cord parenchyma are difficult to remove totally without producing additional @entity16 . In this study, we describe a two-stage resection facilitating total resection of intramedullary @entity5 . CLINICAL PRESENTATION: Three cases of @entity602 were treated using a two-staged method. TECHNIQUE: The first surgery included myelotomy, biopsy and duroplasty. A thin expanded @entity736 sheet was placed between the dorsal surface of the spinal cord and dura mater to prevent adhesions. Two or 3 weeks after surgery, a second surgery was performed to remove the now exophytic @entity5 . RESULTS: Magnetic resonance imaging scans showed exophytic extrusion of the @entity5 in all three cases before the second operation. In each @entity1 , we were able to carry out gross total @entity5 without additional @entity51 except for transient joint position sense loss in one case. All three @entity1 remain neurologically stable without evidence of @entity5 recurrence more than 3 years after surgery. CONCLUSION: A two-stage operation may enhance the surgeon's ability to completely resect extensive low-grade @entity602 and, at the same time preserve neurological function.
