Insights
Annular pancreas, a rare congenital obstruction in infants, causes vomiting and distention. Early diagnosis and surgical intervention, like duodenostomy, are crucial for successful treatment.
Area of Science:
- Pediatric Surgery
- Gastroenterology
- Congenital Malformations
Background:
- Annular pancreas is a rare congenital anomaly causing intestinal obstruction in infants.
- Symptoms like nonbilious vomiting and abdominal distention mimic other common pediatric gastrointestinal issues.
- Accurate diagnosis can be challenging, potentially leading to delayed treatment.
Abstract:
Annular pancreas is a rare congenital intestinal obstruction to be found in infants. It is characterized by nonbilious vomiting, abdominal distention, and feeding intolerance that share similar symptoms with other intestinal obstructions. We reported a case of 11-month-old female infant with a history of nonbilious vomiting after coughing as much as 6 times per day 1 day before admission. The patient had an incorrect provisional diagnosis of hypertrophic pyloric stenosis based on ultrasound. Later on, an upper gastrointestinal series showed dilatation of the second part of the duodenum which was successfully treated by a duodenostomy during laparotomy procedure. It is suggested that treating an intestinal obstruction needs a further investigation when the symptoms were continuously repeated.
