Hello, The observation of a small stomach also implies that observation has to made for other associated anomalies like brain stem defects, tracheo-esophageal fistula, polyhydramnios, esophageal atresia etc. Association of multiple defects and also the amount of the defect determines the prognosis. Overall, the outlook is not too good and you may take an opinion from a perinatologist. As for the mode of delivery, if there is disproportion, vaginal delivery may be allowed as far as the mother is concerned. if the fetus is ate risk, it would be better to go for abdominal delivery. Hope this helps.
