ABSTRACT:

Background and study aims

Analyses of colonoscopy (CS) and esophagogastroduodenoscopy (EGD) complications is crucial for further promoting use of endoscopy. This study analyzed rates of severe complications of CS compared with those of EGD using big data.

Patients and methods

As a study population, we retrospectively used commercially anonymized health insurance claims data covering 3,050,954 patients from January 2010 to December 2020. Patients ≥ 50 years old who underwent CS or EGD without treatment were included in the study. The main outcomes were differences in rates of hemorrhage, perforation, and fatal events between EGD and CS, and risk factors of each complication comparing CS with EGD.
