Background: Duodenal atresia or stenosis are different degrees of the same abnormality. They usually occur at the level of the ampulla of Vater and are thought to be an embryologic defect during the development of the foregut, leading to abnormal recanalization. Complete duodenal atresia is usually symptomatic in the early neonatal period, while partial obstruction (web, stenosis) may have a late presentation and a more challenging diagnosis such as in our case.

Biliary atresia (BA) is the most common cause of the obstructive type of neonatal cholestasis that requires prompt surgical intervention. About 10% of neonates with BA have other congenital anomalies, of which splenic malformation (BASM) is a well-known distinct sub-group. There is sparse literature on the association of duodenal atresia and ductal plate malformation (DPM) in patients of BASM.

Article Synopsis
  • - The case involves a newborn suspected of having duodenal atresia based on prenatal imaging, but postnatal X-rays showed gas in the distal bowel and a possible mass causing pyloric obstruction seen on ultrasound.
  • - Fluoroscopic studies indicated no contrast was passing through the stomach, which led to an operative evaluation.
  • - During surgery, an unusually shaped pylorus with abnormal glandular tissue was found, and a pyloromyotomy was performed, successfully relieving the obstruction without changing the baby's anatomy.

Article Synopsis
  • Radiologic evaluation of neonatal bowel obstruction is complicated due to overlapping clinical features and imaging results from various diagnoses, necessitating a careful analysis of gestational age, clinical signs, and imaging studies.
  • Radiographs help confirm bowel obstruction and discern if it is proximal or distal, but additional imaging, such as upper or lower gastrointestinal contrast studies and ultrasound (US), are crucial for accurate diagnosis.
  • The article reviews various conditions like esophageal atresia, hypertrophic pyloric stenosis, and malrotation with midgut volvulus, highlighting specific imaging patterns and the benefits of using US in the diagnostic process.

Combined esophageal and duodenal atresia: A review of the literature from 1950 to 2020.

Arch Pediatr

August 2023

Department of Visceral and Neonatal Pediatric Surgery, APHP Hôpital Armand Trousseau, Paris, France.

The combination of duodenal atresia (DA) and esophageal atresia (EA) is very rare. With improvements in prenatal sonography and the use of fetal magnetic resonance imaging (MRI), these malformations can be diagnosed in a more accurate and timely manner; polyhydramnios remains the most common sign despite having a low specificity. The high rate of associated anomalies (in 85% of cases) can also impact neonatal management and increase the morbidity rate; thus, it is of paramount importance to look for every possible associated malformation, such as VACTERL and chromosomic anomalies.
