Multiple brain tumor nodule resections under direct visualization of a neuronavigated endoscope.
With neuronavigation-assistance, endoscopic neurosurgery has a variety of advantages for brain tumor resection. However, intraoperative neuronavigation has to be operated by frequently alternating a neuronavigation wand and moving the microscope back-and-forth on the surgical field while the microscope is being used for surgery, except when using stereo overlays in the operating microscope aligned to the operative scene. In our practice, our surgical endoscope was used as a sole optical device and was also calibrated as a virtual wand targeting to tumor nodules while the operation was being performed under its simultaneous visualization. This paper gives a brief description and technical report of applications of image-guided endoscopy in two cases with multiple tumor nodules. ⋯ The neuronavigated endoscope coordinates of the tip of endoscope, and the trajectory of targets, provide both 3D orientation and direct endoscopic visualization simultaneously, and present with the unique feature for solely endoscopic minimally invasive procedures, especially for multiple intracranial lesions.

A new full-endoscopic technique for cervical posterior foraminotomy in the treatment of lateral disc herniations using 6.9-mm endoscopes: prospective 2-year results of 87 patients.
Anterior cervical decompression and fusion (ACDF) is the standard procedure for operation of cervical disc herniations with radicular arm pain. Mobility-preserving posterior foraminotomy is the most common alternative in the case of a lateral localization of the pathology. Despite good clinical results, problems may arise due to traumatization of the access. ⋯ No serious surgical complications occurred. The recorded results show that the full-endoscopic posterior foraminotomy is a sufficient and safe supplement and alternative to conventional procedures when the indication criteria are fulfilled. At the same time, it offers the advantages of a minimally invasive intervention.

Delayed endoscopic intraventricular hemorrhage (IVH) removal and endoscopic third ventriculostomy may not prevent consecutive communicating hydrocephalus if IVH removal was insufficient.
The aim of this study was to investigate whether delayed endoscopic treatment of intraventricular hemorrhage (IVH) can prevent consecutive communicating hydrocephalus. ⋯ Delayed endoscopic IVH removal and ETV might not prevent consecutive communicating hydrocephalus if IVH removal was insufficient.

Case ReportsMinimally invasive endoscopic removal of a herniated nucleus pulposus that had migrated to the S1 nerve root foramen.
In this report, we described an adult case with a lumbar herniated nucleus pulposus that had migrated to the S1 nerve root foramen from L5-S1 disc space. Endoscopically, the migrated mass was successfully removed after laminectomy at the S1 with a small skin incision of 20 mm in length. Unlike the other levels, the intraforaminally migrated mass along the S1 root can be excised without any removal of the facet joints; therefore, additional spinal fusion is not necessary. Thus, an S1 foraminal migrated mass can be a good surgical candidate for minimally invasive endoscopic surgery.

ReviewBalloon-assisted endoscopic retroperitoneal gasless approach (BERG) for lumbar interbody fusion: is it a valid alternative to the laparoscopic approach?
In the last years the use of interbody fusion devices with an anterior spinal lumbar approach has become a common procedure for the treatment of degenerative disc disease and spinal instability. We analysed our series of a simplified endoscopic approach to the anterior spine and made a review of the retroperitoneal endoscopically assisted approach to the anterior lumbar spine in the international literature. ⋯ The BERG technique is a safe, effective, simplified, less technically demanding alternative approach when performing ALIF procedures, without the morbidity associated with laparoscopic or traditional approaches.
