Introduction and objectives:

The adenoma detection rate (ADR) is defined as the presence of at least 1 adenoma in patients ≥ 50 years on a screening colonoscopy. This becomes important due to the association of adenomas and colorectal cancer. It is recommended to have an ADR of 25% in men and women ≥ 50 years. Our goal was to know the ADR of gastroenterology fellows versus attending physicians.

Materials and methods:

We performed an observational, descriptive, and retrospective study where we reviewed medical records of patients who underwent a colonoscopy in the period of 2 years. Demographic, clinical data and the ADR of fellows and attending physicians were analyzed.

Results:

We evaluate 363 procedures: Fellows performed 279 and attending physicians performed 84. Polyps were found in 112 patients, and the mean age was 58 years (17-90). The ADR for men and women ≥ 50 years for fellows and attending physicians was 23% versus 31.7% (p = 0.18) respectively.

Conclusion:

Gastroenterology fellows achieved an ADR slightly below the international standards, with an ADR of 23% among men and women ≥ 50 years, compared to 31.7% of attending physicians.
