Overview
Congenital duodenal obstruction refers to structural anomalies causing blockage of the duodenum, often presenting in neonates but occasionally diagnosed in adults. It encompasses various etiologies including duodenal diaphragm, annular pancreas, and extrinsic compression 34.Diagnosis
Clinical Presentation: Nausea, vomiting, palpable abdominal mass, and symptoms related to malnutrition or specific underlying conditions (e.g., pellagra) 12.
Imaging: CT is highly useful for diagnosis, particularly in identifying aortoduodenal syndrome and other structural abnormalities 1.
Radiographic Findings: Reversed double bubble sign indicative of malrotation and multiple organ malrotation syndrome 3.
Endoscopic and Surgical Exploration: May be necessary for definitive diagnosis and management in complex cases 4.Management
Surgical Intervention: Primary treatment for most congenital obstructions; specific procedures include pyloroplasty, duodeno-jejunostomy, and excision of the duodenal diaphragm 43.
Adjunctive Treatments: Gastroenterostomy or duodeno-jejunostomy depending on the extent of obstruction and anatomical anomalies 5.
Nutritional Support: Essential in managing complications like pellagra due to malabsorption 2.Special Populations
Pediatrics: Early surgical intervention is crucial to prevent long-term complications; follow-up monitoring for complications like blind pouch-syndrome is necessary 7.
Adults: Rare presentations may require tailored surgical approaches based on underlying pathology (e.g., congenital bands, malrotation) 6.Key Recommendations
Primary Surgical Repair: Early surgical correction is recommended for congenital duodenal obstructions to prevent morbidity 34 (Evidence: Strong).
Imaging with CT: Utilize CT for accurate diagnosis, especially in suspected aortoduodenal syndrome 1 (Evidence: Moderate).
Long-term Follow-up: Regular follow-up is essential in pediatric patients to monitor for late complications such as blind pouch-syndrome 7 (Evidence: Moderate).References
