Endoscopy is one of the most frequently performed procedures for the early diagnosis and treatment of many diseases and plays a crucial role in the diagnosis and treatment of upper gastrointestinal disorders. Sometimes, endoscopy may be the only option for detecting certain diseases of the stomach and larynx. However, for many patients, endoscopy is considered an invasive, highly painful, and extremely uncomfortable procedure. Furthermore, anxiety and fear felt before the procedure can cause physical and emotional discomfort, disrupt patient comfort, and cause pain.
