Introduction and objectives: The adenoma detection rate (ADR) has been investigated as a formal method in the evaluation of a trainee or resident physician. Several studies have suggested that water-assisted colonoscopy methods increase the ADR, especially in the right colon, when compared to air-insufflated methods alone. The objective of this study is to compare the adenoma detection rates between the techniques of the second frontal view examination and "Underwater" examination by residents, supervised by a senior endoscopist. Patients and methods: This is a prospective, comparative and randomized clinical trial. The patients referred to the Cancer Hospital of Barretos for colonoscopy, and who agreed with the study, were divided into two groups, one with the use of water and the other only with air insufflation. The primary endpoint of this study is to compare adenoma detection rate. Secondary outcomes were withdrawal time, proportion of intubation of the cecum, preparation of the colon, and number of previously performed colonoscopies in the ADR in both techniques.
