Clinical Results Of Percutaneous Fibrin Gel Injection Versus Surgical Cystectomy In Symptomatic Sacral Canal Cysts

Objective:To evalute the clinical outcomes of two different surgicaltreatments for symptomatic sacral canal cysts.Methods:From June2003to April2011,48cases of symptomaticsacral canal cysts were treated by trans-laminar fibrin gel injection under Carm X-ray machine guided (group A,30cases) and traditonal simple sacrallaminectomies with resection of the cysts (group B,18cases). Preoperativedata and postoperative lumbosacral pain and function improvement wereanalyzed and compared between two groups.Results:The operative time, bleeding, length of stay andcomplications rate in group A were significantly less than those in group B(P＜0.01). For two groups, there were significant differences in visualanalogue scale score and Oswestry functional disability index betweenpreoperation and postoperation (P＜0.01),and in the rate of functionimprovement between two groups (P＜0.05) but in the rate of lumbosacralpain improvement(P＞0.05). The improvement time of lumbosacral pain and function in group A is shorter than that in group B.According to therating scale, the excellent and good rates of pain improvement were88%ingroup A and71%in group B; the excellent and good rates of functionimprovement were88%in group A and71%in group B.Conclusion:C arm X-ray machine guided fibrin gel therapy forsymptomatic sacral canal cysts is a simple, safe, repeatable and effectivetherapy.
