There has been substantial debate on the issue of how often one should undergo surveillance colonoscopy procedures to detect colorectal cancer (CRC) at an early stage and improve survival. Recent studies and advice from disease authorities suggest that patients who are not considered high-risk can be allowed a few more years in between procedures.
Now, a study led by University Medical Center Utrecht scientist Bas Oldenburg, MD, PhD, suggests that patients with active inflammatory bowel disease (IBD) who regularly have surveillance colonoscopy have a lower occurrence of interval CRC, meaning they can allow up to 5 years before having to undergo another surveillance colonoscopy. The study was recently published in the journal Clinical Gastroenterology and Hepatology and it is entitled "Incidence of Interval Colorectal Cancer Among Inflammatory Bowel Disease Patients Undergoing Regular Colonoscopic Surveillance".
To arrive at this conclusion, Dr. Oldenburg and his fellow researchers conducted a retrospective analysis of IBD patient information. They gathered data on 1,273 IBD patients (34% Crohn’s disease, 63% ulcerative colitis, 3% unclassified) who underwent a total of 4,327 surveillance colonoscopies between January 1, 2000 and January 1, 2014. Patients were monit
