OBJECTIVES: Flexible endoscopy plays a crucial role in detecting, diagnosing, and treating gastrointestinal (GI) disorders. Optimal visualization during the procedure can be challenging and may lead to lesions being missed or incomplete resections of lesions. Ultimately, this may result in higher costs for the healthcare system, due to missed lesions progressing further and needing more invasive treatment, and lesions being removed with insufficient resection margins requiring repeat interventions. A new imaging technology for GI endoscopes is Extended Depth of Field (EDOF), which is designed to allow precise observations and better visualization. This can improve screening effectiveness and subsequently reduce healthcare costs. As current research on EDOF is limited, we conducted a survey among clinicians to assess their experiences with EDOF.
METHODS: An online cross-sectional questionnaire was conducted among gastroenterologists in Europe. The questionnaire consisted of various question-formats, including Likert-scales and open- and closed-ended questions. Data were analyzed using descriptive statistics.
RESULTS: In total, 83 responses from 16 countries were gathered. Most of the respondents agreed that endoscopes with EDOF contribute to an improved detection of lesions in the upper GI tract (95% agreed) and in the lower GI tract (88% agreed). Eighty-nine percent of physicians agreed that the broader focus of EDOF enhances the visualization during endoscopic treatment and 86% agreed that the EDOF technology supports a more precise assessment of resection margins. That this helps to increase the rate of complete resections was agreed to by 67% of the respondents.
CONCLUSIONS: Most of the respondents agreed that EDOF contributes to an improved detection of lesions and enhances visualization during resection. Future research should evaluate the clinical impact of EDOF on the rate of detection and complete resection of lesions. This would also allow to assess the impact of EDOF on the treatment costs of GI disorders.
