Sasagawa Y, Tanaka S, Kinoshita M, Nakada M. Endoscopic and exoscopic surgery for brain tumors. Int J Clin Oncol 2024:10.1007/s10147-024-02529-9. [PMID: 38976183 DOI: 10.1007/s10147-024-02529-9] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/14/2024] [Accepted: 04/04/2024] [Indexed: 07/09/2024]
Abstract
Nerves and blood vessels must be protected during brain tumor surgery, which has traditionally relied on microscopes. In the 2000s, endoscopes and related equipment were developed for neurosurgery. In this review, we aim to outline the role of endoscopes in brain tumor surgery and discuss the emerging use of exoscopes. The primary use of endoscopes in brain tumor surgery is in endoscopic endonasal surgery for pituitary tumors. By using the space within the sphenoid sinus, surgeons can insert an endoscope and instruments such as forceps or scissors through the nose to access and remove the tumor. Compared to microscopes, endoscopes can get closer to tumors, nerves, and blood vessels. They enable wide-angle observation of the skull base, making them valuable for skull base tumors as well as pituitary tumors. Endoscopes are also used in cases where a brain tumor is associated with hydrocephalus, allowing surgeons to correct obstructive hydrocephalus and perform tumor biopsies simultaneously. Exoscopy, a newer technique introduced in recent years, involves surgeons wearing special glasses and removing the tumor while viewing a three-dimensional monitor. This approach reduces surgeon fatigue and allows for more natural positioning during lengthy brain tumor surgeries. Future brain tumor surgeries will likely involve robotic surgery, which is already used for other organs. This is expected to make brain tumor removal safer and more accurate.

Exoscope Use in Spine Surgery: A Systematic Review of Applications, Benefits, and Limitations. World Neurosurg 2024; 184:283-292.e3. [PMID: 38154686 DOI: 10.1016/j.wneu.2023.12.102] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 10/31/2023] [Revised: 12/18/2023] [Accepted: 12/18/2023] [Indexed: 12/30/2023]
Abstract
BACKGROUND Exoscopes were recently developed as an alternative to the operative microscope (OM) and endoscope for intraoperative visualization during neurosurgery. Prior reviews studying mixed cranial and spinal surgical cohorts reported advantages with exoscope use, including improved ergonomics and teaching. In recent years, there has been an increase in exoscope research, with no updated systematic review focused exclusively on the benefits and limitations of exoscope use in spine surgery. Thus, we sought to systematically synthesize the literature related to exoscope-assisted spine surgery. METHODS A literature search was conducted using the PubMed, Embase, Scopus, Cochrane, and Web of Science databases to identify relevant studies reported between 2010 and September 2023. Data, such as the exoscope model used, procedure types performed, and user observations, were then collected. RESULTS A total of 31 studies met our inclusion criteria, including 481 patients with spine pathologies who underwent a surgical procedure using 1 of 9 exoscope models. The lumbar region was the most frequently operated area (n = 234; 48.6%), and discectomies comprised the most overall procedures (n = 273; 56.8%). All patients benefited clinically. The reported advantages of exoscopes compared with OMs or endoscopes were improved focal distance, surgeon posture, trainee education, compactness, and assistant participation. Other aspects such as stereopsis, illumination, and cost had various observations. CONCLUSIONS Exoscopes have advantages compared with OMs or endoscopes during spine surgery. The user learning curve is minimal, and no negative patient outcomes have been reported. However, some aspects of exoscope use necessitate longer term prospective research before exoscopes can be considered a standard tool in the armamentarium of intraoperative visualization strategies.

Abstract
BACKGROUND The growing interest in exoscopic (EX) technology has prompted a comprehensive evaluation of its clinical, functional, and financial outcomes in neurosurgery. This systematic review and meta-analysis aimed to explore the utilization of EX in spine surgery and assess their safety, efficacy, and impact on surgical outcomes. METHODS A thorough literature review was conducted using PubMed, Scopus, and Embase databases in accordance with Preferred Reporting Items for Systematic Reviews and Meta-Analyses guidelines. The study focused on articles concerning the application of EXs in spinal surgical procedures. The inclusion criteria encompassed various study designs presenting clinical data and intraoperative experiences related to EX utilization in spine surgery. RESULTS The meta-analysis included studies examining various aspects of EX utilization, such as intraoperative complications, video/image quality, surgical field visualization, ease of manipulation, ergonomic characteristics, educational utility, surgical duration, and team involvement. Findings indicated that EXs offered superior video quality and favorable ergonomic features. Comparable outcomes were observed in surgical duration, intraoperative blood loss, time to discharge, and postoperative pain levels between EX and conventional microscope approaches. CONCLUSIONS This study provides valuable insights into the utilization of EXs in spine surgery, demonstrating their potential advantages and comparable outcomes with conventional microscopes.

Abstract
3D exoscopy based on Video Telescope Operating Monitor (VITOM) technology provides good visualization quality and portability. There are few data on comparison of extracorporeal telescoping with microsurgical techniques in spinal surgery. OBJECTIVE To compare the effectiveness of VITOM 3D exoscopy and microsurgical techniques in spinal surgery. MATERIAL AND METHODS A prospective study included 80 patients (54 men and 26 women). Two groups were distinguished: group 1 (ES, n=40) - VITOM 3D exoscopy, group 2 (SM, n=40) - Pentero 900 surgical microscope. We analyzed surgery time, postoperative rehabilitation, hospital-stay and complications. ES and microsurgical technique were compared using the questionnaire by Takahashi S. and rapid upper limb assessment (RULA). RESULTS Conventional microsurgical technique was characterized by less surgery time (p<0.05) and morbidity (p=0.02). Postoperative rehabilitation and hospital-stay were similar (p=0.26 and p=0.39, respectively). Image quality in ES was comparable to microsurgical technique in shallow accesses and manipulations perpendicular to skin incision. Availability of neurosurgical instruments at different depths of the wound channel was comparable in both groups. The limitation of ES was length of skin incision, depth of the wound and its visualization at certain angle. These features required expansion of surgical approach or conversion of intervention. In general, surgeons rated intraoperative posture comfort as comparable in both groups that was consistent with the RULA scale. CONCLUSION VITOM 3D exoscopy is an alternative to traditional microscopy and more ergonomically beneficial in spinal surgery in case of manipulations perpendicular to skin incision and shallow wide accesses. There are several important limitations of this device including difficult manipulations in narrow deep wounds and visualization under certain angle.
