Contrast-enhanced computed tomography – an effective tool in identifying pancreatic duct disruption in acute pancreatitis: A case series

Pancreatic duct disruption may follow acute pancreatitis, chronic pancreatitis, pancreatic surgery, and trauma. Diagnosis in these patients is usually made by endoscopic retrograde cholangiopancreaticogram or secretin-stimulated magnetic resonance cholangiopancreaticogram. We report five cases where pancreatic duct disruption was diagnosed by contrast-enhanced computed tomography (CECT). Five patients with acute pancreatitis were studied; three were secondary to alcohol and two were posttraumatic. Three patients developed pancreatic ascites, one developed pancreatico-pleural effusion, and the other had pancreatic pseudocyst. CECT of the abdomen revealed pancreatic ductal injury in all the patients. In one patient with pancreatic ascites, multiple peripancreatic collections and dilated and disrupted pancreatic duct communicating with the peritoneal cavity were noted. The patient of traumatic pancreatitis had a fracture of the head of the pancreas, with peripancreatic collection communicating with the main pancreatic duct (MPD). In the other traumatic pancreatitis, there was a pseudocyst near the head of pancreas communicating with the MPD. CECT can provide a comprehensive assessment in acute pancreatitis including duct integrity, type and location of pancreatic ductal injury and can be an effective noninvasive alternative imaging modality in diagnosing pancreatic duct disruption
