Congenital duodenal obstruction: the impact of an antenatal diagnosis

Insights
Antenatal ultrasound diagnosis of congenital duodenal obstruction aids parental preparation for infant surgery. Early diagnosis did not alter surgical outcomes but improved parental coping mechanisms.
Area of Science:
- Pediatric Surgery
- Fetal Medicine
- Neonatology
Background:
- Congenital duodenal obstruction is a significant neonatal surgical emergency.
- Antenatal diagnosis allows for early planning of neonatal surgical interventions.
- The impact of antenatal diagnosis on parental coping and infant outcomes requires further investigation.
Purpose of the Study:
- To evaluate the impact of antenatal diagnosis of congenital duodenal obstruction on parental preparedness and infant outcomes.
- To compare clinical characteristics and surgical outcomes between antenatally and postnatally diagnosed infants.
- To assess the influence of antenatal diagnosis on the timing of surgical intervention.
Main Methods:
- Retrospective review of 34 infants with congenital duodenal obstruction.
- Analysis of antenatal ultrasound diagnoses, parental counseling, and postnatal management.
- Comparison of birth weight, gestational age, associated anomalies, surgical timing, and survival rates between groups.
Main Results:
- Fifteen of 34 infants were diagnosed with duodenal obstruction antenatally.
- Antenatal diagnosis facilitated parental preparation for neonatal surgery.
- Infants diagnosed antenatally underwent earlier surgical repair, but overall survival rates were similar (88% overall, 94% post-repair).
- Associated congenital anomalies were more frequent in postnatally diagnosed infants.
- No significant difference in mean birth weight or gestational age between antenatal and postnatal diagnosis groups.
Conclusions:
- Antenatal diagnosis of duodenal obstruction positively influences parental coping with the anomaly.
- While antenatal diagnosis leads to earlier surgery, it does not alter the overall outcome for infants with duodenal obstruction.
- Severe associated congenital anomalies remain a primary factor influencing mortality.
Abstract:
In a series of 34 infants with congenital duodenal obstruction, 15 were diagnosed by antenatal ultrasound between the fifth month of gestation and term. Fourteen patients were available for follow-up. In 10 of 14 cases, patients were available for follow-up. In 10 of 14 cases, parents were informed of the diagnosis antenatally and, in 9, were advised of the possibility of surgery in the neonatal period. Parents felt the information helped them prepare for the surgical and medical interventions necessary in the postnatal management of their infants. The mean birth weight and gestational age of these infants were comparable with those diagnosed postnatally. Associated congenital anomalies were more common in the patients with a postnatal diagnosis. In the total group of 34 infants with duodenal obstruction, 32 had surgical repair with a survival rate of 94%. Surgical procedures were comparable between the two groups. Surgical intervention occurred earlier in the neonatal period when an antenatal diagnosis was made. Overall survival in the entire series was 88% with four deaths attributed to severe associated congenital anomalies. We conclude that (1) the antenatal diagnosis of duodenal obstruction influences parents positively in coping with the anomaly, and (2) although surgery was performed sooner, the outcome of infants with duodenal obstruction was not changed by providing an antenatal diagnosis.
