Insights on High-Value Procedures From the ISASS 4-Part Webinar Series on Current and Emerging Techniques in Endoscopic Spine Surgery Based on Surgeon Experience.

Background: The authors conducted a comprehensive review and integration of insights from 4 webinars hosted by the International Society for the Advancement of Spine Surgery (ISASS) to arrive at recommendations for best clinical practices for guideline development for endoscopic spine surgery. This perspective article discusses the limitations of traditional surgical trials and amalgamates surgeons' experience and research on various cutting-edge techniques.

Methods: Data were extracted from surveys conducted during each webinar session involving 3639 surgeons globally.

Evaluation of training models for intraventricular neuroendoscopy.

Structured surgical education has become increasingly important in recent years. Intraventricular neuroendoscopic procedures have been widely established. However, training surgical skills with these techniques is crucial for young residents due to the potential harm to adjacent tissue.

Predicting the long-term course: Shunt surgery results in idiopathic normal pressure hydrocephalus-a comprehensive study.

Background: Idiopathic normal pressure hydrocephalus is a neurological disorder primarily affecting the elderly. Shunt surgery is the gold standard treatment, yet long-term outcome remains poorly investigated, especially concerning neuropsychological performance, motor skills and quality of life. This study aimed to evaluate the long-term effects of shunting in iNPH patients up to three years post-surgery.

Epigenetic Characteristics in Primary and Recurrent Glioblastoma-Influence on the Clinical Course.

Objective: Epigenetic tumor characteristics are in focus for glioblastoma prognosis. This raises the question if these characteristics present with stable expression during the progression of the disease, and if potential temporal instability might influence their prognostic value.

Methods: A total of 44 patients suffering from glioblastoma who were treated for their primary and relapse tumors were included in the study.

Endonasal endoscopic or endoscopic-assisted transcranial surgery of Rathke's cleft cysts: does the approach and surgical technique influence the radicality and recurrence rate?

Objective: Resections of symptomatic Rathke's cleft cysts (RCCs) are mainly performed via an endonasal transsphenoidal approach. However, there is a lack of equivalent data in current literature concerning transcranial keyhole approach in the treatment of RCCs. In order to find general recommendations for the surgical treatment of RCCs also with regard to recurrence, the object of this study is the analysis and comparison of both techniques.
