High-Definition 4K-3D Exoscope in Spine Surgery: A Single-Center Experience and Review of the Literature. MEDICINA (KAUNAS, LITHUANIA) 2024; 60:1476. [PMID: 39336517 PMCID: PMC11434260 DOI: 10.3390/medicina60091476] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Subscribe] [Scholar Register] [Received: 07/12/2024] [Revised: 09/01/2024] [Accepted: 09/05/2024] [Indexed: 09/30/2024]
Abstract
Background and Objectives: Binocular optical microscopy (OM) paved the way for a new era in brain and spine neurosurgery fields with the introduction of microsurgery. Despite its enormous contribution to modern neurosurgery, OM presents some intrinsic limitations that surgeons need to face during procedures such as prolonged non-ergonomic positions and decreased vision quality to the assistant eyepiece. To overcome these limitations, in recent years, new operative tools have been introduced, such as exoscopes. Here, we present our experience with exoscopes in spine surgery. Materials and Methods: In the period between January 2022 and December 2023, we gradually implemented the use of a high-definition 4K-3D exoscope (ORBEYETM, Olympus, Japan) in patients undergoing spinal surgery. Results: A total of 243 patients underwent spine surgery with exoscope magnification (47 intradural tumors, 99 lumbar degenerative cases, 79 cervical degenerative cases, 5 dorsal calcified disk herniations, 4 dural arteriovenous fistulas (dAVFs), and 9 others). We compared this cohort with a similar cohort of patients operated in the same period using OM based on different endpoints: operating time, complication rate, and infection rate. We did not find any statistically significant difference in any of the endpoints between these two groups. Conclusions: In our experience, the exoscope provides a better resolution of spinal anatomy and higher quality real-time images of the surgery for the entire OR team and improves the ergonomic posture of both surgeons, without lengthening the operating time and without increasing the rate of adverse events. Prospective studies with a larger cohort of patients are needed to further validate these findings.

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.

Implementation of Robotic Exoscope in Minimally Invasive Corpectomy at Thoracolumbar Junction for the Treatment of Traumatic Spinal Cord Compression. World Neurosurg 2024; 184:23-28. [PMID: 38184228 DOI: 10.1016/j.wneu.2023.12.163] [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: 12/10/2023] [Revised: 12/29/2023] [Accepted: 12/30/2023] [Indexed: 01/08/2024]
Abstract
The development and diffusion of minimally invasive (MI) approaches have coincided with improvements in magnification systems. The exoscope will probably open a new era in new technologies in spinal surgery. This study reports a retrospective series of 19 thoracolumbar (T11-L2) burst fractures with anterior column failure and cord compression, treated with MI corpectomy and spinal decompression assisted by a three-dimensional high-definition exoscope (Video 1). Exclusion criteria were pathologic or osteoporotic fractures, multilevel fractures, and previous surgery at the site of the fracture. Three key indicators were recorded: surgical time, blood loss, and intraoperative complications. A questionnaire was administered to assess the users' exoscope experience with ergonomics, preparation, magnification, image definition, illumination, and user-friendliness, compared with the operative microscope. To the best of our knowledge, this is the first study reporting on exoscope-assisted MI corpectomy. This procedure permitted low blood loss and less surgical time without intraoperative complications. The exoscope offers clear advantages in terms of ergonomics, definition, and user-friendliness. Moreover, it is a suitable instrument for training and education, providing an opportunity for better interaction with other members of the surgical staff.

[PMID: 36836941 PMCID: PMC9966143 DOI: 10.3390/life13020584] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2023] [Revised: 02/02/2023] [Accepted: 02/18/2023] [Indexed: 02/22/2023] Open
Abstract
Background: In recent years, three-dimensional exoscopes have been increasingly applied in neurosurgery. Multiple exoscopic systems are available, all offering specific features. In this study, we assessed practical and visualization performance of four different exoscopic systems in a highly challenging microsurgical procedure, and evaluated whether these affected the quality of work. Methods: We included four different exoscopes: Olympus ORBEYE, Zeiss KINEVO, Storz VITOM, and Aesculap AEOS. With each exoscope, ten experimental bypass procedures were carried out on chicken wing vessels at a depth of 3 cm. We evaluated the quality of the anastomoses, the practical considerations for the setup of the exoscopic systems, and the visualization quality by tracking the number of unnecessary movements. Results: All included exoscopes enabled us to perform the bypass procedures with mostly adequate or excellent results. Surgically, the most pronounced difference between the exoscopes was the duration of the procedure, which was mainly due to the number of unnecessary movements. Practically, the exoscopes differ highly which is important when considering which exoscope to apply. Conclusions: This is the first study comparing different exoscope systems while performing the same challenging microsurgical procedure. We found major practical differences between the exoscopes that determine the suitability of an exoscope based on the demands and conditions of the surgical procedure. Therefore, preprocedural practical training with the exoscope is required.
