Overview
Congenital duodenal stenosis involves narrowing of the duodenal lumen, often affecting the third portion, leading to symptoms such as vomiting and feeding difficulties, particularly in neonates and infants 1.Diagnosis
Clinical Presentation: Frequent vomiting, feeding intolerance 1.
Endoscopic Findings: Severe edematous stenosis without ulceration, bleeding, or neoplasm 1.
Imaging: Multiphase contrast-enhanced CT recommended; key findings include:
- Homogenous swelling and luminal stenosis on unenhanced images.
- Band-like area of lower contrast enhancement in pancreatic phase.
- Possible celiac axis stenosis and anterior pancreaticoduodenal artery aneurysms 1.Management
Surgical Intervention: Primary treatment often involves surgical repair, such as duodenojejunostomy or duodenoplasty 1.
Endoscopic Therapy: May be considered in selected cases, though less common for congenital cases 1.
Supportive Care: Nutritional support and management of complications like dehydration 1.Special Populations
Pediatrics: Congenital duodenal stenosis predominantly affects neonates and infants, requiring early intervention 1.
Comorbidities: No specific management adjustments noted for comorbidities in the provided abstracts 1.Key Recommendations
Utilize multiphase contrast-enhanced CT for definitive diagnosis, identifying characteristic imaging features 1 (Evidence: Moderate).
Primary surgical repair is recommended for congenital duodenal stenosis to alleviate symptoms and ensure proper growth 1 (Evidence: Expert opinion).
Endoscopic evaluation should be considered in cases where surgical intervention is not immediately feasible, though surgical repair remains the mainstay 1 (Evidence: Weak).References
