[Mediastinitis Associated with Mediastinal Pancreatic Pseudocyst Successfully Treated by Thoracoscopic Mediastinal Drainage].

Abstract

Pancreatic pseudocysts rarely extend to the mediastinum and can be fatal if mediastinitis is complicated. In this report, we describe a case of mediastinitis associated with mediastinal pancreatic pseudocyst successfully treated by the thoracoscopic mediastinal drainage. The patient was a man in his 40s with a history of alcoholic acute pancreatitis. Chest and abdominal computed tomography (CT) scan taken for his complaints of back pain and dyspnea showed a pancreatic pseudocyst extending to the mediastinum. First, an endoscopic nasopancreatic drainage( ENPD) tube was placed, and then thoracoscopic mediastinal drainage was performed through the right thoracic cavity. After the operation, the pseudocyst in the mediastinum rapidly disappeared even though there was no drainage from the ENPD tube. Postoperative recovery of the patient was uneventful, and the patient was discharged on the 17th postoperatively day. This case suggests that the importance of prompt treatment for mediastinitis and the effectiveness of the thoracoscopic surgery.
