UNASSIGNED: Background: The specific recognition of @entity354 ( @entity354 ) with or without a @entity292 in a foetus is a diagnostic challenge for prenatal medicine. The aim of the present work is to analyse the value of the measurement of gastric size in the diagnosis of this significant @entity600 . Materials and Methods: Altogether, the examinations of 433 pregnancies between the 18.4 and 39.1 weeks of gestation were retrospectively analysed. 59 of these foetuses exhibited an @entity354 . By means of a linear regression analysis with normal foetuses, significant parameters influencing gastric size were examined. Subsequently the gastric sizes were transformed into z values and a comparison was made between @entity354 with and without fistulae with the help of t tests. Results: In the normal foetuses there was a significant association between the gastric circumference and the abdominal circumference (circumference   =   6.809   +   0.179 * abdominal circumference, r   =   0.686, p   <   0.0001). In the normal group the average was 43.0 (standard deviation [SD] 13.7) mm and those in foetuses with and without fistuale were 33.8 (SD 22.7) and 0.9 (SD 3.7) mm. In 34 (57.6%) foetuses with an @entity354 , the gastric circumference was below the 5th percentile. In detail, there were 13 (34.2%) foetuses with a @entity292 and 21 (100%) without a @entity292 . The average z values in the normal group and in the groups of @entity354 with @entity292 and without @entity292 amounted to 0.0 (SD 1.0), -1.3 (SD 2.2) and -4.5 (SD 1.0). Conclusion: Measurements of the gastric circumference below the 5th percentile should lead to further diagnostic measures, especially when associated with @entity2978 . Although @entity354 without a @entity292 is always conspicuous, only about one in three @entity29624 with @entity292 are associated with a significantly smaller stomach.
