Overview
Causes
It is typically associated with abnormal embryological development, however adult cases can develop.
Presentation
- The anomaly may be discovered incidentally in asymptomatic patients.
- In others, annular pancreas is associated with duodenal stenosis, postbulbar ulcerations, pancreatitis, or biliary obstruction.
- Early signs of abnormality include polyhydramnios, or an excess of amniotic fluid, low birth weight, and feeding intolerance immediately after birth.
Diagnosis
Postnatal diagnostic procedures include abdominal x-ray and ultrasound, CT scan, and upper GI and small bowel series.
Diagnostic Findings
- ERCP: An aberrant pancreatic duct communicating with the main pancreatic duct and encircling the duodenum.
- CT or MRI studies may show normal pancreatic tissue, with or without a small pancreatic duct, encircling the duodenum.
- Upper GI series: Narrowing of the second portion of the duodenum.
Treatment
Surgical resection is recommended for symptomatic cases.
Treatment usually is bypassing the obstructed segment of dudenum by duodeno-doudenostomy. Another approach is laparoscopic gastrojejunostomy.[1]
