Abstract

BackgroundTo present a surgical technique for the treatment of intradural extramedullary (IDEM) tumors by using endoscopically controlled surgery with open hemilaminectomy technique.MethodsIn this study, 20 patients with 22 IDEM tumors were enrolled. An endoscopically controlled surgery with open hemilaminectomy was employed to remove the tumors. Data related to clinical symptoms and medical images before and after surgery were collected for perioperative evaluation and follow-up analysis.ResultsAll the tumors in 20 patients were well removed. The clinical symptoms were significantly reduced in all the patients as well. The short-term follow-up data showed that there was no tumor recurrence or spinal deformity.ConclusionThe endoscopically controlled surgery with open hemilaminectomy technique provided favorable exposure and satisfactory resection to the IDEM tumors. It may be an effective surgical method for treating IDEM tumors. Larger samples and longer follow-up data are needed to verify its long-term effectiveness.

Highlights

To present a surgical technique for the treatment of intradural extramedullary (IDEM) tumors by using endoscopically controlled surgery with open hemilaminectomy technique
The hemilaminectomy approach has been taken as an effective method for treating intradural extramedullary (IDEM) spinal tumors [1,2,3]
We reported the short-term outcomes of those patients who underwent endoscopically controlled surgery with open hemilaminectomy technique

Summary

Introduction

To present a surgical technique for the treatment of intradural extramedullary (IDEM) tumors by using endoscopically controlled surgery with open hemilaminectomy technique. Conclusion: The endoscopically controlled surgery with open hemilaminectomy technique provided favorable exposure and satisfactory resection to the IDEM tumors. It may be an effective surgical method for treating IDEM tumors. The hemilaminectomy approach has been taken as an effective method for treating intradural extramedullary (IDEM) spinal tumors [1,2,3]. To achieve an appropriate surgical exposure and reduce retracting to the spinal cord during surgery, we (2021) 7:1 attempted to perform an endoscopic technique in our institute. During the past 2.5 years, 20 patients with IDEM spinal tumors underwent endoscopically controlled surgery with open hemilaminectomy technique. We reported the short-term outcomes of those patients who underwent endoscopically controlled surgery with open hemilaminectomy technique
