Treatment of chronic pancreatitic pleural effusion by percutaneous catheter drainage of abdominal pseudocyst.
A 53-year-old man entered the hospital with a large, right chronic pancreatitic pleural effusion. Computed tomographic examination of the abdomen and chest demonstrated a pancreatic pseudocyst that had extended into the mediastinum. After conventional closed-chest tube thoracotomy drainage failed to empty the pleural space, percutaneous abdominal pseudocyst drainage was instituted using computed tomographic guidance. The pleural effusion cleared promptly, and the pancreatic pseudocyst resolved gradually over seven weeks. Following termination of pseudocyst drainage, the patient has remained well for over two years with no recurrence of pancreatitis, pseudocyst, or pleural effusion. In contrast, three earlier patients with a chronic pancreatitic effusion managed conventionally had a complicated hospital course and required surgical intervention; two had recurrent pancreatitis following hospital discharge. Percutaneous catheter placement was unsuccessful in one of these three and, in retrospect, was infeasible in the other two. It is recommended that thoracoabdominal computed tomography be performed in all patients with a chronic pancreatitic pleural effusion, and that percutaneous abdominal catheter drainage be attempted in all patients with an accessible pancreatic or mediastinal pseudocyst. Such treatment may relieve respiratory insufficiency, minimize the risk of empyema or fibrothorax, and may promote pseudocyst closure without the need for surgery.
