A 59-year-old woman with alcoholic chronic pancreatitis and multiple readmissions for exacerbation developed acute shortness of breath. Chest X-ray showed massive rightsided pleural effusion, and a thoracocentisis revealed amylase content of 12,000 U/L. Magnetic resonance cholangiopancreatography (MRCP) suggested presence of the pancreatic pseudocyst in the porta hepatitis with possible pancreaticopleural fistula (PPF). Pleural effusion recurred soon after thoracocentesis despite treatment with total parenteral nutrition (TPN) and somatostatin. An endoscopic retrograde cholangiopancreatography (ERCP) was not possible secondary to duodenal stenosis caused by the inflammatory pancreatic head mass. The patient underwent an exploratory laparatomy during which a direct pancreatic ductogram demonstrated the PPF tract (Figs. 1 and 2). Fistula was outlined by the methylene blue injection into the main pancreatic duct. A Frey procedure (pancreatic head local resection and pancreatojejunostomy), to provide decompression of the pancreatic duct, as well a gastrojejunostomy and feeding jejunostomy were performed. Postoperative course was complicated by bleeding from pancreatic branches of the splenic artery, requiring embolization per interventional radiology. There was no recurrence of PPF on subsequent 3 years follow-up.
DiscussionPPF is the rare complication of pancreatitis, with the incidence of 0.4-4.5%. 1-3 Only 63 cases have been reported so far in the English literature. Majority of patients are alcoholics with chronic pancreatitis in which PPF develops as the sequela of the incompletely formed/ ruptured pancreatic pseudocyst or direct pancreatic duct leak. Most common presenting symptom is shortness of breath due to the pleural effusion. Thoracocentesis reveals elevated amylase content. PPF could be demonstrated by ERCP, MRCP, or CT with sensitivity 78%, 80%, and 47%, respectively. 2 Medical therapy with TPN and somatostatin is effective in only 30-60% of the cases. ERCP with pancreatic stent placement results in resolution of PPF in majority of the cases. 4 In our patient, ERCP was not possible because of the duodenal stenosis. Surgery is used Figure 1 Intraoperative photo showing cored pancreatic head and longitudinal opening of the pancreatic duct.
