The New England Journal of Medicine recently reported in a study of over 300,000 colonoscopies, rates of adenoma detection among 136 gastroenterologists varied from 7.4 to 52.5 percent. Patients who had screening colonoscopy performed by gastroenterologists with higher rates of detecting adenomas were at lower risk for both interval advanced-stage colorectal cancer (CRC) and fatal interval CRC. Your physicians at ADH track their adenoma detection rates carefully and are consistently well above the national average.
