Pancreatic pseudocysts communicating with the stomach: demonstration by endoscopic retrograde pancreatography

The use of endoscopic retrograde pancreatography (ERP) provides important information in the management of pancreatic pseudocysts unavailable by other methods. When the pseudocysts communicate with a hollow viscus, the surgeon is better able to deal with the problem if aware of this fact prior to operative intervention. A pancreatic pseudocyst communicating with the stomach was demonstrated by ERP in each of four patients. One of these patients had pancreatic ascites and the other had left-sided pleural effusion, and both were treated successfully by distal pancreatectomy. The other two patients responded to nonoperative treatment. This report emphasizes the potential diagonstic value of ERP in determining the presence and the fate of pseudocysts.
