Microsurgical Treatment And Prognosis Of Myxopapillary Ependymoma Conus And Filaments Of The Spinal Cord

Objective:To analyze the microsurgical treatment and prognosis of Myxopapillary ependymoma Conus and filaments of the spinal cord.Provide some reference for its treatment.Methods:Retrospective analysis of clinical data Conus and filaments of the spinal cord the First Affiliated Hospital of Kunming Medical University Department of general surgery from January 2012 to January 2018 were 10 cases by surgery and pathology confirmed papillary mucinous filum ependymoma patients,the clinical manifestations,treatment and recurrence analysis.Results:The first symptom was numbness or pain(n = 7),Fecal incontinence(n =3),and physical examination(n = 2),Two recurrences(n=1).Preoperative McCormick spinal cord function score:I grade(7cases),II grade(3cases).Waist(9cases),lumbosacral(2 cases).10 cases of spinal endoptic myxoid papillary ependymoma were completely cut in 9 cases and subtotal resection in 1 cases.The total resection rate was 90%.All the clinical symptoms were obviously improved when they were discharged from hospital.10 patients were followed up for an average of 42.6 months.During the follow-up period,7 patients had normal neurological function,2 patients suffered from fecal incontinence,and two relapsed patients had numbness of the lower extremities.9 patients in this group had no recurrence during the follow-up period,and the two recurred patients recurred again.Conclusions:1.Microsurgical removal of the lesion is the preferred treatment for the treatment of mucocutaneous Myxopapillary Ependymoma in the Conus and filaments of the spinal cord.2.The position,size,degree of adhesion and surgical skill are the main factors affecting the prognosis of the patients with myxoid ependymoma of theConus and filaments of the spinal cord.3.During the operation of mucinous papillary ependymoma of the Conus and filaments of the spinal cord,we should maximize the protection of normal neurological function and mimimize tumor recurrence rate.
