Pancreas divisum

Pancreas divisum is a congenital anomaly in the anatomy of the ducts of the pancreas in which a single pancreatic duct is not formed, but rather remains as two distinct dorsal and ventral ducts. Most individuals with pancreas divisum remain without symptoms or complications. A minority of people with pancreatic divisum may develop episodes of abdominal pain, nausea or vomiting due to acute or chronic pancreatitis. The presence of pancreas divisum is usually identified with cross sectional diagnostic imaging, such as endoscopic retrograde cholangiopancreatography (ERCP) or magnetic resonance cholangiopancreatography (MRCP). In some cases, it may be detected intraoperatively. If no symptoms or complications are present, then treatment is not necessary. However, if there is recurrent pancreatitis, then a sphincterotomy of the minor papilla may be indicated.
