Pancreaticopleural fistula. An unusual cause of persistent unilateral pleural effusion

Pancreaticopleural fistula causing pleural effusion: a case report and review of the literature

BACKGROUND

Pancreaticopleural fistula is a rare complication of pancreatitis and poses diagnostic and therapeutic challenges. This case report sheds light on the unique challenges posed by pancreaticopleural fistula as a rare complication of pancreatitis. The aim is to contribute valuable insights to the scientific literature by presenting a case involving a middle-aged man with acute necrotizing pancreatitis and associated pleural effusion.

CASE PRESENTATION

A 41-year-old Asian male with a history of pancreatitis and chronic alcohol use presented with severe dyspnea, chest pain, and left-sided pleural effusion. Elevated serum amylase lipase levels and imaging confirmed acute necrotizing pancreatitis with a computed tomography severity index of 8/10. Magnetic resonance cholangiopancreatography revealed pancreatic necrosis and pseudocyst formation and findings suggestive of pancreaticopleural fistula. The patient was then treated with octreotide therapy.

CONCLUSION

The management of pancreaticopleural fistula demands a comprehensive and individualized approach. Recognition guided by high clinical suspicion coupled with appropriate investigations and a careful balance between medical, endoscopic, and surgical interventions is crucial for achieving favorable outcomes. This case report adds to the scientific literature by providing insights into the complexities of pancreaticopleural fistula and emphasizing the importance of personalized strategies in its management.

Endoscopic management of pancreaticopleural fistula in a pediatric patient: A case report and literature review

INTRODUCTION

Pancreaticopleural fistula (PPF) is a rare but serious complication of pancreatic disorders. As the clinical presentations of PPF are often deceptive, it can cause a delay in the timely diagnosis and proper treatment. PPF is extremely uncommon in pediatric patients, and diagnostic and management strategies for PPF among pediatric patients are scanty.

PATIENT CONCERNS

A 12-year-old girl presented with cough and dyspnea owing to massive right-side pleural effusion confirmed by Chest X-ray. Biochemical examination of pleural effusion revealed a significant elevation of amylase level. Imaging modalities showed dilated pancreatic duct and fistulous tract connecting pancreatic duct and right thorax.

DIAGNOSIS

Chronic pancreatitis with PPF was diagnosed.

INTERVENTIONS

Medical therapy was initially attempted for 2 weeks. Endoscopic therapy with naso-pancreatic drainage tube placement was then performed without any complications after failed medical therapy.

OUTCOMES

The patient has remained healthy and symptom-free during 2 years of follow-up.

CONCLUSION

When pediatric patients presented with recurrent pleural effusion with unknown etiology, PPF should be taken into consideration. Pleural effusion amylase level is the most important laboratory test and magnetic resonance cholangiopancreatography is recommended to visualize the fistula. Optimal management of PPF should be based on pancreatic duct morphology.

Successful Diagnosis and Treatment of a Pancreaticopleural Fistula in a Patient Presenting with Unusual Empyema and Hemoptysis

Pancreaticopleural fistula (PPF) is a rare complication in patients with pancreatitis. Its symptoms are similar to those of empyema or pleural effusion; therefore, it is important to consider PPF in the differential diagnosis. Herein, we describe the diagnosis and treatment of PPF in a patient presenting with unusual empyema and delayed hemoptysis.

Diagnosis and management of pancreaticopleural fistula

Pancreaticopleural fistula is a rare diagnosis requiring a high index of clinical suspicion due to the predominant manifestation of thoracic symptoms. The current literature suggests that confirmation of elevated pleural fluid amylase is the most important diagnostic test. Magnetic resonance cholangiopancreatography is the recommended imaging modality to visualise the fistula, as it is superior to both computed tomography and endoscopic retrograde cholangiopancreatography (ERCP) in delineating the tract within the pancreatic region. It is also less invasive than ERCP. While a trial of medical regimen has traditionally been the first-line treatment, failure would result in higher rates of complications. Hence, it is suggested that management strategies be planned based on pancreatic ductal imaging, with patients having poor chances of spontaneous closure undergoing either endoscopic or surgical intervention. We also briefly describe a case of pancreaticopleural fistula in a patient who was treated using a modified Puestow procedure after failed endoscopic treatment.

Unusual case of persistent unilateral pleural effusion secondary to pancreaticopleural fistula

INTRODUCTION

Pancreaticopleural fistula is rare. It occurs as a complication in acute and chronic pancreatitis. Here we report a case of persistent unilateral pleural effusion secondary to pancreaticopleural fistula.

PRESENTATION OF CASE

A 37 year old non alcoholic gentleman who had no history of pancreatitis and presented with breathlessness and tachypenia. X-ray chest showed massive pleural effusion on the right side. Amylase estimation of the tapping fluid was very high. ERCP showed a pancreaticopleural fistula.

DISCUSSION

Pancreaticopleural fistula is a rare entity with an incidence of 0.4-4.5%. It occurs either as a complication in pancreatitis, or after injury of the pancreatic duct. A greatly elevated pleural fluid amylase is usually the first step towards the diagnosis. ERCP and CT will identify the fistulous tract in 70%. Treatment is mainly directed towards intercostal drainage and control of the fistula.

CONCLUSION

Presentation is misleading in most of cases and needs aware clinicians with a high index of suspicion.

Optimizing management of pancreaticopleural fistulas

AIM: To evaluate the management of pancreaticopleural fistulas involving early endoscopic instrumentation of the pancreatic duct.

METHODS: Eight patients with a spontaneous pancreaticopleural fistula underwent endoscopic retrograde cholangiopancreatography (ERCP) with an intention to stent the site of a ductal disruption as the primary treatment. Imaging features and management were evaluated retrospectively and compared with outcome.

RESULTS: In one case, the stent bridged the site of a ductal disruption. The fistula in this patient closed within 3 wk. The main pancreatic duct in this case appeared normal, except for a leak located in the body of the pancreas. In another patient, the papilla of Vater could not be found and cannulation of the pancreatic duct failed. This patient underwent surgical treatment. In the remaining 6 cases, it was impossible to insert a stent into the main pancreatic duct properly so as to cover the site of leakage or traverse a stenosis situated downstream to the fistula. The placement of the stent failed because intraductal stones (n = 2) and ductal strictures (n = 2) precluded its passage or the stent was too short to reach the fistula located in the distal part of the pancreas (n = 2). In 3 out of these 6 patients, the pancreaticopleural fistula closed on further medical treatment. In these cases, the main pancreatic duct was normal or only mildly dilated, and there was a leakage at the body/tail of the pancreas. In one of these 3 patients, additional percutaneous drainage of the peripancreatic fluid collections allowed better control of the leakage and facilitated resolution of the fistula. The remaining 3 patients had a tight stenosis of the main pancreatic duct resistible to dilatation and the stent could not be inserted across the stenosis. Subsequent conservative treatment proved unsuccessful in these patients. After a failed therapeutic ERCP, 3 patients in our series developed superinfection of the pleural or peripancreatic fluid collections. Four out of 8 patients in our series required subsequent surgery due to a failed non-operative treatment. Distal pancreatectomy with splenectomy was performed in 3 cases. In one case, only external drainage of the pancreatic pseudocyst was done because of diffuse peripancreatic inflammatory infiltration precluding safe dissection. There were no perioperative mortalities. There was no recurrence of a pancreaticopleural fistula in any of the patients.

CONCLUSION: Optimal management of pancreaticopleural fistulas requires appropriate patient selection that should be based on the underlying pancreatic duct abnormalities.

Hemothorax as the clinical presentation of a pancreaticopleural fistula: report of a case

Pancreaticopleural fistula is a rare complication of acute pancreatitis with pancreatic pseudocyst. We report the case of a 39-year-old man admitted for respiratory distress. Chest X-ray showed a pleural effusion, and thoracentesis yielded bloody fluid. Computed tomography (CT) scan showed a multiloculated pleural effusion and sagittal reconstruction revealed a fistulous tract between the pleura and a pancreatic pseudocyst. We treated the acute hemothorax complicating the pancreaticopleural fistula by performing urgent thoracotomy with the evacuation of blood and clots and lung decortication. We also gave the patient somatostatin and performed endoscopic retrograde cholangiopancreatography with sphincterotomy, and placed a pancreatic stent. The patient recovered well.

Pancreaticothoracic fistulas: imaging findings in five patients

BACKGROUND

Pancreaticothoracic fistulas are a rare complication of chronic pancreatitis. This study evaluated the imaging findings in patients with pancreaticothoracic fistulas.

METHODS

We retrospectively reviewed the medical records and radiographic images in five patients with pancreaticothoracic fistulas diagnosed at our institution during the previous 6 years. Data from radiography, endoscopic retrograde cholangiopancreatography (ERCP), computed tomography (CT), magnetic resonance cholangiopancreatography, and drainage catheter studies were evaluated.

RESULTS

Persistent pleural effusions were present on the radiographs of all patients. ERCP was performed in three patients. Contrast material was injected into drainage catheters placed in a pancreatic pseudocyst in one patient and a pancreatic abscess in another patient. Pancreaticothoracic fistulas were demonstrated on all of these studies. One patient had a CT study immediately after ERCP and another patient had a CT study immediately after contrast material was injected through a drainage catheter placed percutaneously in a pseudocyst. CT demonstrated the full extent of the pancreaticothoracic fistula in both patients.

CONCLUSION

Pancreaticothoracic fistulas are rare and may require multiple imaging modalities to establish a diagnosis.
