Analysis of pancreaticopleural fistula in 5 children / 中华实用儿科临床杂志

ABSTRACT

Objective To summarize the clinical features of the pancreaticopleural fistula (PPF) in children in order to improve the understanding of PPF and to make early diagnosis and treatment of the disease.Methods Five cases of pediatric PPF in Beijing Children's Hospital Affiliated to Capital Medical University from December 2007 to March 2014 were studied by retrospective analysis.The clinical features, laboratory results, image characteristics, treatment and prognosis were reviewed.Results Five cases of PPF were diagnosed aged between 2 years to 10 years and 5 months old, history from more than 1 month to 6 months.The main symptoms were chest tightness (3 cases), chest pain (3 cases) , fever(3 cases) , wheeze (1 case) , dyspnea (1 case).Only 1 case was with abdominal pain and abdominal distension when he was admitted to hospital.All patients had massive pleural effusions, included right side (3 cases),left side(1 case) ,bilateral sides(1 case), 1 case complicated with massive ascites.Pleural fluid amylase of all the cases was significantly elevated (＞ 1 000 U/L) ,the highest was more than 50 000 U/L.Four cases had positive findings of pancreas by transabdominal ultrasound.Five cases had morphological changes in pancreas by magnetic resonance cholangiopancreatography (MRCP).Four cases had PPF and pancreatic pseudocysts respectively.Conservative treatment was given to 5 cases, but further 3 cases reveived stent insertion by endoscopic retrograde cholangiopanereatography, and 2 cases reveived surgical therapy.Conclusions PPF is rare in children, the main clinical feature is massive pleural effusion with respiratory symptoms.Pleural fluid amylase would be significantly elevated.The diagnosis of PPF generally relies on imaging, MRCP is considered the imaging study of choice for PPF due to its superiority in identifying a fistula in the pancreatic region and its noninvasiveness as compared to endoscopic retrograde cholangio pancreatography.Endoscopic and surgical therapy can be used if internal therapy is not satisfactory.
