Lipid Mediators in Colonic Biopsies as Biomarkers of Disease Activity of Inflammatory Bowel Diseases

"Colonoscopy or coloscopy can provide a visual diagnosis and grants the opportunity for biopsy or removal of suspected colorectal cancer lesions.~The endoscope is then passed through the anus up the rectum, the colon, and ultimately the terminal ileum. The endoscope has a movable tip and multiple channels for instrumentation, air, suction and light. Biopsies are frequently taken for histology, needed for cancer or IBD diagnosis.~Extra-biopsies for research purpose will only be performed if the clinician decides that they are necessary for the clinical diagnosis or for the disease follow-up.~For this protocol, collecting these extra biopsies should last under 5 minutes and should not extend the procedure by more than this time."
