Pancreatic duct disruption and duodenal hematoma associated with endoscopic retrograde cholangiopancreatography.

We have reported a case of intraduodenal duct disruption and duodenal hematoma associated with ERCP. The location of the extravasated contrast material created a confusing picture, which preoperatively was thought to be a pseudocyst, but was found at operation to be a duodenal hematoma. In retrospect, the upper gastrointestinal series done immediately after ERCP was very helpful. We believe that an upper GI series done immediately after ERCP will help determine the location of unusual collections of contrast material seen at ERCP.
