Abstract
Background and study aims Third space endoscopy (TSE), including per-oral endoscopic myotomy and endoscopic submucosal dissection, is technically challenging and physically demanding. The aim of this study was to assess the prevalence and types of musculoskeletal symptoms and injuries (MSI) in third space endoscopists and its impact on clinical practice. Materials, Patients and methods A 22-item survey measuring endoscopist characteristics, procedure volumes, MSI, and its effect on clinical practice was distributed to endoscopists practicing TSE. Descriptive statistics were used to depict MSI. Logistic regression was used to identify predictors for MSI related to TSE. Results The survey was completed by 45 of 110 endoscopists (40.9 %) who received the survey, representing 10 countries across four continents. Thirty-one (69 %) endoscopists reported current MSI with 71 % (n = 22/31) believing these began after starting TSE, and 48.9 % (22/45) reporting more symptoms after TSE compared to endoscopic ultrasound/endoscopic retrograde cholangiopancreatography. Common MSI included the shoulders (42.2 %), back (37.8 %), neck (33.3 %), and wrist (24.4 %). Lower extremity MSI were also reported with foot symptoms (11.1 %) being most common. A minority required disability (2.2 %), change in endoscopy scheduling (6.7 %) or surgery (2.2 %). Only 15.6 % of endoscopists had received prior ergonomics training. Logistic regression revealed no significant predictors for MSI. Conclusions Over two-thirds of endoscopists performing TSE suffer from MSI, with many reporting onset of their symptoms after starting TSE in their practice. Further studies are needed to understand and reduce the risk of MSI in TSE given the growing demand for these procedures and the potential long-term impact of this occupational hazard.
