Upper gastrointestinal endoscopy (esophagogastroduodenoscopy, EGD) includes visualization of the oropharynx, esophagus, stomach, and proximal duodenum, with real-time assessment and interpretation of the findings encountered. A variety of technical and cognitive aspects must be mastered in order to perform a high-quality examination. The basic technical components of upper endoscopy also serve as the platform upon which many therapeutic interventions are based.

The elements of high-quality performance in endoscopy have been well described and include the following [1,2]:

Prior to the procedure

Appropriate indications and adherence to guidelines

Suitable environment with adequate support team
