False pancreas divisum: not a difficult diagnosis
1Upgraded Department of Medicine, S M S Medical College & Hospital, Jaipur.
Summary
False pancreas divisum, a rare condition, can be identified by specific pancreatic duct abnormalities seen on ERCP. These features, including duct displacement and lack of arborization, aid in diagnosis following trauma or in cases of pancreatic cancer.
Area of Science:
- Gastroenterology
- Radiology
- Surgical Pathology
Background:
- Pancreas divisum is a congenital anomaly of the pancreatic duct system.
- False pancreas divisum presents as a ductal obstruction mimicking the congenital form.
- Understanding its features is crucial for accurate diagnosis and management.
Observation:
- This study analyzed six cases of false pancreas divisum diagnosed via ERCP.
- Patients presented with obstructive jaundice or abdominal pain.
- Underlying causes included pancreatic carcinoma, trauma, and pancreatitis with pseudocyst.
Findings:
- ERCP revealed a blocked pancreatic duct, absent terminal arborization, and variable duct dimensions.
- Pancreatic trauma cases showed duct displacement towards the common bile duct.
- A branch to the uncinate process was observed in 40% of cases, with contrast leakage in 33%.
Implications:
- Clinical and pancreatographic findings like duct displacement, lack of arborization, and contrast leakage suggest false pancreas divisum.
- Accurate identification is vital for appropriate treatment, especially in cases of malignancy or trauma.
- Further research into the long-term outcomes and optimal management strategies is warranted.
