AccuMeasure is a novel technology, that has emerged as a promising tool for measuring polyps and lesions during colonoscopies. The system employs laser-based measurements, enabling precise determination of lesion size, depth, and extent. The main hypotheses this study aims to evaluate are:\n\n* AccuMeasure technology, with its precise laser measurements, will demonstrate superior accuracy and reliability in assessing lesion size of pathologies encountered during endoscopies, when compared to other endoscopic scoring methods.\n* AccuMeasure measurements will show strong construct validity by correlating significantly with endoscopic subscores, symptomatic remission (CD PRO2 \\\u003C8, partial mayo score), and fecal calprotectin values.",[49,50],"Polyp of Colon","Crohn Disease","2026-08-13",{"date":53,"type":54},"2026-08-18","ACTUAL",{"date":56,"type":54},"2025-05-09",{"date":58,"type":45},"2027-11",{"name":5,"class":6},1]
