Overview
Clinical presentation may range from being asymptomatic to showing a variety of signs and symptoms resulting from fluid accumulation such as nausea, vomiting, hypotension, infection, tachycardia, pain, weight loss, ileus and severe symptoms such as unrelenting pain and sepsis. External pancreatic fistula presents with pancreatic fluid accumulation noticeable on the skin surface. Internal pancreatic fistula may present with ascites or pleural effusion as fluid accumulates within the abdominal or thoracic cavity. Complications following a pancreatic fistula may include Wound infection and sepsis, Hemorrhage, Internal and/or external fistula, Pancreatic pseudocyst, Delayed gastric emptying, Walled off pancreatic necrosis, Prolongation of the hospital stay, Pancreatic ascites, High amylase pleural effusion, Disconnected duct syndrome, Multisystem involvement eventually leading to multiorgan failure and/or death. Pancreatic fistula that are less severe are reported to heal in a duration of 4-6 weeks with conservative management only. 80% of the external fistula and 50-65% of the internal fistula are reported to close eventually with conservative measures which involve stabilization of the patient with supportive therapies. However, pancreatic fistula can lead to significant morbidity if not addressed on time. Surgical intervention provides resolution of the fistula with a 90-92% success rate.
Natural History
History and clinical presentation depends upon the size, location and connection of the pancreatic fistula with the involved organ or cavity.[1][2]
Clinical presentation may range from being asymptomatic to showing a variety of signs and symptoms resulting from fluid accumulation such as nausea, vomiting, hypotension, infection, tachycardia, pain, weight loss, ileus and severe symptoms such as unrelenting pain and sepsis.
External pancreatic fistula presents with pancreatic fluid accumulation noticeable on the skin surface.[3]
Internal pancreatic fistula may present with ascites or pleural effusion as fluid accumulates within the abdominal or thoracic cavity.[2]
Complications
Anterior disruption of a pseudocyst or a pancreatic duct leads to leakage of pancreatic secretions into the free peritoneal cavity, leading to pancreatic ascites[4][5]. If the duct is disrupted posteriorly, the secretions leak through the retroperitoneum into the mediastinum via the aortic or esophageal hiatus. Once in the mediastinum, the secretions can either be contained in a mediastinal pseudocyst, lead to enzymatic mediastinitis, or, more commonly, leak through the pleura to enter the chest and form a chronic pancreatic pleural effusion[6][7].Complications arising from a pancreatic fistula are due to the undrained pancreatic fluid accumulation and erosions caused by the enzymatically active substances of the fluid which affects the surrounding tissues. The most commonly observed complications are:[8][9]
- Wound infection and sepsis
- Hemorrhage
- Internal and/or external fistula
- Pancreatic pseudocyst
- Delayed gastric emptying
- Walled off pancreatic necrosis
- Prolongation of the hospital stay
- Pancreatic ascites
- High amylase pleural effusion
- Disconnected duct syndrome
- Multisystem involvement eventually leading to multiorgan failure and/or death.
Prognosis
Pancreatic fistula that are less severe are reported to heal in a duration of 4-6 weeks with conservative management only. 80% of the external fistula and 50-65% of the internal fistula are reported to close eventually with conservative measures which involve stabilization of the patient with supportive therapies. However, pancreatic fistula can lead to significant morbidity if not addressed on time. Surgical intervention provides resolution of the fistula with a 90-92% success rate.[10][11]
