Full pathway

1. [Decision] Stomach bubble + fluid + upper pouch (MRI)
   Stomach bubble + amniotic fluid + upper pouch (fetal MRI)? (EA ± TEF prenatal suspicion = absent/small stomach bubble + polyhydramnios (>25 weeks); but in TEF >80% a distal fistula lets the stomach show and is missed (sensitivity ~40%). The upper cervical pouch sign is more specific. Fetal MRI accuracy is better than ultrasound (absent stomach bubble + esophageal/pouch dilation combination).)
   • Absent/small stomach bubble + polyhydramnios ± upper blind-ending pouch (suspect EA ± TEF) → Suspect EA ± TEF · MRI confirm + check associated
   • Stomach bubble normal but polyhydramnios/suspicious (distal TEF can be missed) → Stomach bubble seen but suspicious · watch for missed diagnosis
2. [End] Suspect EA ± TEF · MRI confirm + check associated
   Suspect EA ± TEF (absent/small stomach bubble + polyhydramnios ± upper cervical pouch sign): fetal MRI to confirm (stomach volume ≤0.06 mL sensitivity 90%, upper pouch); with VACTERL/CHARGE/trisomy 18 (~20%)/cardiac anomaly ~50% (poor prognosis) → karyotype/microarray + echocardiography + detailed anatomy; serial ultrasound fluid monitoring (polyhydramnios + short cervix → amnioreduction); deliver at a NICU + surgical center.
3. [End] Stomach bubble seen but suspicious · watch for missed diagnosis
   Stomach bubble seen but polyhydramnios/suspicious (possible distal TEF): EA has low sensitivity and is easily missed; serial ultrasound + fetal MRI to assess the esophagus/upper pouch + check associated (VACTERL/cardiac) + karyotype; confirmed postnatally by inability to pass a gastric tube/choking; deliver at a NICU center.
