Abstract:Introduction Echogenic bowel is diagnosed in 0.2-1.4% of all second trimester scans. Although often a normal variant, it is associated with a fivefold increase of chromosomal abnormalities and IUGR. In particular it is a known soft marker for trisomy 21. This study investigates the antenatal management and pregnancy outcomes of patients given a diagnosis of echogenic bowel at Lancashire Women and Newborn Centre (LWNC). Methods The case notes of all women given a diagnosis of fetal echogenic bowel in 2015 were reviewed. A proforma was designed to extract information about diagnosis, associated abnormalities, antenatal screening, delivery details and pregnancy outcome. Results There were 12 diagnoses of echogenic bowel made at LWNC in 2015. Associations with bleeding in pregnancy and maternal TORCH infections, particularly CMV were noted. No association was demonstrated with Down's syndrome however, this may be due to a low uptake of antenatal screening. Two cases resulted in small-for-gestational-age babies. There was one case of FDIU observed. The fetus had a normal XX karyotype and placental insufficiency was identified on pathological testing. Conclusion All cases were managed appropriately and it is evident that good outcomes can be achieved with appropriate antenatal care. Women with a diagnosis of fetal echogenic bowel should be offered antenatal Down's Syndrome, Cystic Fibrosis and TORCH infection screening with serial growth scans. As this study has a small sample population, it would be beneficial to continue to collect data over the next 5 years to observe for further trends.
