Colon Cancer, Dysplasia, and Surveillance in Patients with Ulcerative Colitis
Abstract
Most gastroenterologists and current textbooks1 2 3 recommend that patients who have had widespread ulcerative colitis for 7 to 10 years should be entered into a surveillance program designed to detect colonic dysplasia (precancer). This involves frequent colonoscopies with multiple mucosal biopsies. The recommended frequency of colonoscopy is any time from every year to every three years. Although there is no clear rationale for choosing one interval over another, the Medical Knowledge Self-Assessment Profile, a publication of the American College of Physicians, states that patients with long-term extensive ulcerative colitis should have a colonoscopy every year.4 The argument for surveillance in such . . .

About these checks
Registry, retraction, Cites and statistics results are computed, not judged, with one exception: a printed reference that no index lists is read once by a model before it counts as a citation error. Claims are extracted by a model and kept only when their quote appears verbatim in the text; each cited source is then checked, with a model’s help, for whether it says what the claim relies on. Those verdicts can be wrong — read the claim’s quote and the cited source before relying on one.
Statistics and arithmetic are recomputed, not judged.
Confidence bands are shown only for fields calibrated on our annotated test set. None is calibrated yet, so no band is shown.
