Role of Virtual Reality in Gastrointestinal Endoscopy Training and Teaching

Gastrointestinal (GI) endoscope is one of the instruments used extensively in the diagnosis and treatment of digestive tract disorders. China is confronted with a great demand for endoscopists working in grassroots healthcare facilities. Furthermore, endoscopic retrograde cholangiopancreatography (ERCP), endoscopic ultrasonography (EUS), and endoscopic submucosal dissection (ESD) are becoming the prevailing methods of endoscopic treatment of digestive diseases. Therefore, there is a growing demand for senior endoscopists. Currently, an important focus of GI endoscopy training is the acceleration of standardized training for endoscopists working in grassroots health facilities and advanced training for senior endoscopists. Simulation devices based on virtual reality technology exhibit strengths in objectivity, authenticity, and an immersive experience. These devices show advantages in the training method, the number of participants, and assessment over traditional training programs for GI endoscopy. Their application provides a new approach to the training and teaching of GI endoscopy. Herein, we summarized the explorations and practices of using virtual reality technology in the training and teaching of GI endoscopy, analyzed its application status in China, and discussed its prospects for future application.
