Overview
Pancreas divisum is a congenital anomaly characterized by an embryological failure in the fusion of the dorsal and ventral pancreatic ducts, leading to an obstruction or narrowing at the minor papilla and potentially causing recurrent pancreatitis or other pancreatic disorders 1.Diagnosis
Ultrasonography: Primary imaging modality with 82% success rate in visualizing the pancreas 1.
Key Criteria:
- Pancreatic head thickness: 11-30 mm
- Isthmus thickness: 4-21 mm
- Corpus-caudate area thickness: 24-32 mm
- Abnormal shape (e.g., non-sausage, dumb-bell, or tadpole) or thickness deviations suggest pathology 1.Management
Endoscopic Therapy: Primary treatment often involves endoscopic retrograde cholangiopancreatography (ERCP) with minor papilla sphincterotomy to relieve ductal obstruction 1.
Surgical Intervention: Reserved for cases refractory to endoscopic management or severe complications 1.Special Populations
No Specific Guidance: Abstracts do not provide specific management recommendations for pregnancy, pediatrics, elderly, or comorbid conditions 1.Key Recommendations
Utilize ultrasonography as the initial diagnostic tool for suspected pancreas divisum due to its high visualization success rate 1 (Evidence: Moderate).
Consider endoscopic retrograde cholangiopancreatography with sphincterotomy for definitive treatment of symptomatic pancreas divisum 1 (Evidence: Moderate).
Surgical intervention may be necessary in cases where endoscopic therapy fails or complications arise 1 (Evidence: Expert opinion).References
