Sequential adaptive e-learning and hands-on simulator training for unilateral biportal endoscopy (UBE) of the lumbar spine - results from an EANS Young Neurosurgeons hands-on course.

Abstract

Unilateral biportal endoscopy (UBE) is a minimally invasive surgical (MIS) technique utilized for lumbar decompression, which has recently gained popularity in Europe. We aimed to explore the value of sequential adaptive e-learning, followed by simulator-based hands-on training modules for UBE at the occasion of the 2024 EANS Young Neurosurgeons meeting. An adaptive e-learning was designed by learning engineers (Area 9 Lyceum), based on theoretical content provided by two endoscopic spine surgeons. A two-module simulator training, consisting of an insight-the-box model (basic tasks for eye-hand coordination), followed by a realistic lumbar spine model (execution of an endoscopic decompression) was developed. Course participants completed the e-learning before the hands-on training course. Course experience was evaluated through a standardized self-assessment questionnaire containing a 5-point Likert scale and a 10-point numeric rating scale. Eleven of eighteen (61%) participants with different levels of professional education (62.5% residents in 1^st -6^th year of training, 37.5% board-certified) completed both trainings. Thirteen participants (72%) had no prior experience with UBE. The perception of knowledge after the e-learning module increased from 2.5 (SD 2) to 6.5 (SD 1.8; p = 0.039). The usefulness, enjoyment, and efficiency of the courses averaged a score of 8.0 (SD 1.8). Regarding the hands-on training, participants estimated an average increase in their skills from 2.9 (SD 1.8) to 6.8 (SD 2, p = 0.028). The overall rating of the two-module course was 7.9 (SD 2.2). Sequential e-learning and simulator training appear to be an effective educational adjunct to establish novel, MIS-techniques such as UBE.
