Persistent Nonbilious Vomiting in a Child: Possible Duodenal Webbing.

Area of Science:

• Pediatric Surgery
• Gastrointestinal Malformations

Background:

• Malrotation and congenital duodenal webbing are distinct gastrointestinal anomalies.
• Their co-occurrence is exceptionally rare in pediatric surgical literature.

Purpose of the Study:

• To report on the rare association of malrotation with congenital duodenal webbing.
• To emphasize the diagnostic considerations for this condition.

Main Methods:

• Presentation of a case series of four patients with malrotation and duodenal webbing from two institutions.
• Comprehensive review of existing published reports on this specific pathology.

Main Results:

• The study identified 94 reported cases of duodenal pathology associated with malrotation.
• Only 15 of these cases (15.9%) specifically involved both malrotation and a duodenal web.
• This highlights the infrequent nature of this combined presentation.

Conclusions:

• Nonbilious vomiting in pediatric patients warrants consideration of duodenal pathology.
• Surgeons should maintain a high index of suspicion for duodenal webs even in the presence of known malrotation.
