Thoracic manifestations of internal pancreatic fistulas caused by chronic pancreatitis are rare conditions. The three main types of these manifestations are mediastinal pseudocysts, pancreatico pleural fistulas and pancreaticobronchial fistulas. We report on one patient with the clinical presentation of all three thoracic internal pancreatic fistulas with a communication to a pseudoaneurysm of the splenic artery caused by chronic alcohol-related pancreatitis. Conservative therapy over four weeks was not successful. Resection of the pseudoaneurysm, debridement of the mediastinal pseudocyst and duodenum preserving resection of the pancreas treated all complications and prevents recurrence in this patient with chronic pancreatitis.

15 to 30% of the patients with chronic pancreatitis develop an inflammatory mass in the pancreatic head. The leading symptoms of these patients are severe upper abdominal pain and complications of the surrounding organs. From 1969 to 1995, 380 patients were treated with a duodenumpreserving pancreatic head resection. The cause of the disease was alcohol abuse in 81%. 93% of the patients suffered from severe pain with recurrent pain attacks. CT-scan revealed enlargement of the pancreatic head (> 4 cm in diameter) in 79% of the patients. 83% of the patients had an impaired exocrine pancreatic function; 48% of the patients had an impaired glucose tolerance or were diabetic. The hospital mortality was 0.8%; 5% of all patients had to be reoperated. The mean duration of the hospitalization was 13.9 days. 89% of the patients showed an unchanged endocrine function in the early postoperative course. The glucose metabolism was improved in 9%, 2% had a deteriorated function. The duodenum-preserving pancreatic head resection is a procedure with a low postoperative mortality and morbidity without deterioration of the endocrine pancreatic function.
