Abstract
This study explored the use of transperineal intestinal ultrasound (TPIUS) for assessment of ulcerative colitis (UC) in pregnancy. 8 pregnant women with UC underwent TP-US, clinical assessment and fecal calprotectin. TP-IUS was well tolerated and feasible with adequate rectal views obtained in all trimesters of pregnancy. No correlation between TP-IUS, clinical, or biochemical rectal disease activity assessment was found in this small cohort. Further studies are required to define the optimal technique and references ranges in the pregnant population.
