Recent publications assessing colonoscopy missed rates of colorectal cancer have generated efforts toward colonoscopy quality improvement. To date, esophagogastroduodenoscopy (EGD) has escaped similar scrutiny in Western populations. Raftopoulos et al. (1) report an upper gastrointestinal cancer missed rate of up to 6.7% in a cohort of 28,000 patients who underwent EGD at a hospital-based endoscopy unit in Perth, Western Australia. Of the missed esophageal and gastric cancers, approximately 80% of patients had alarm symptoms and 73% had abnormalities reported at the time of EGD. The missed cancers may not have been visualized, or were visualized and either not biopsied or biopsied inadequately, or interpreted incorrectly by pathologists. There was no difference in survival between the missed cancers and those detected at the index EGD.
