The incidence of gastric cancer remains high in South Korea. Upper gastrointestinal (GI) endoscopy, i.e., esophagogastroduodenoscopy (EGD), has a higher diagnostic specificity and sensitivity than the upper GI series. Additionally, EGD has the ability to biopsy, through taking a tissue of the pathologic lesion. Successful training of EGD procedural skills require a few important things to be learned and remembered, including the posture of an examinee (e.g., left lateral decubitus and supine) and examiner (e.g., one-man standing method vs one-man sitting method), basic skills (e.g., tip deflection, push forward and pull back, and air suction and infusion), advanced skills (e.g., paradoxical movement, J-turn, and U-turn), and intubation techniques along the upper GI tract (e.g., oral cavity, pharynx, larynx including vocal cord, upper and middle and lower esophagus, gastroesophageal junction, gastric fundus, body, and antrum, duodenal bulb, and descending part of duodenum). In the current review, despite several limitations, we explained the intubation method of EGD for beginners. We hope this will be helpful to beginners who wish to learn the procedure.
Core tip: The demand for esophagogastroduodenoscopy (EGD) has been increasing annually, especially in Asian countries. However, it is challenging to learn the procedure, due to its long learning curve. Therefore, care must be taken in teaching, learning, and practicing the procedure. We believe that if beginners learn how to perform EGD properly through an adequate training program and then perform the procedure effectively on patients, the safety and satisfaction of patients undergoing EGD will be improving.
