Insights
Pancreaticopleural fistula (PPF) is rare, often stemming from pancreatitis or pancreatectomy. Minimally invasive treatments, including stent insertion, effectively manage most cases, preventing recurrence over long-term follow-up.
Area of Science:
- Gastroenterology
- Thoracic Surgery
- Interventional Radiology
Background:
- Pancreaticopleural fistula (PPF) is an uncommon complication.
- Patients often experience nutritional compromise and sepsis.
- Long-term follow-up data for PPF is limited.
Purpose of the Study:
- To describe the long-term outcomes of patients with pancreaticopleural fistula.
- To analyze the etiology, investigation, and treatment of PPF.
- To establish the efficacy of a step-up treatment approach.
Main Methods:
- Retrospective review of 11 patients with PPF treated at a specialist center.
- Analysis of causation, diagnostic imaging, and therapeutic interventions.
- Assessment of treatment outcomes and recurrence rates during long-term follow-up.
Main Results:
- Pancreatitis (9 cases) and distal pancreatectomy (2 cases) were the primary causes of PPF.
- Cross-sectional imaging and ERCP identified duct disruption.
- Minimally invasive treatments, including pancreatic duct stenting and percutaneous drainage, were successful in most cases.
- Surgical intervention was required for refractory empyema in three patients.
- No recurrence of PPF was observed in resolved cases over a median follow-up of 50 months.
Conclusions:
- Pancreatic duct disruption is the common link in PPF, regardless of etiology.
- A step-up approach utilizing minimally invasive techniques is effective for managing PPF.
- Surgery is reserved for refractory sepsis cases, with good long-term outcomes reported.
Background:
Pancreaticopleural fistula (PPF) are uncommon. Complex multidisciplinary treatment is required due to nutritional compromise and sepsis. This is the first description of long-term follow-up of patients with PPF.
Methods:
Eleven patients with PPF treated at a specialist unit were identified. Causation, investigation, treatment and outcomes were recorded.
Results:
Pancreatitis was the etiology of the PPF in 9 patients, and in the remaining 2 the PPF developed following distal pancreatectomy. Cross-sectional imaging demonstrated the site of duct disruption in 10 cases, with endoscopic retrograde cholangiopancreatography identifying the final case. Suppression of pancreatic exocrine secretion and percutaneous drainage formed the mainstay of treatment.Five cases resolved following pancreatic duct stent insertion and three patients required surgical treatment for established empyema. There were no complications. In all cases that resolved there has been no recurrence of PPF over a median follow-up of 50 months (range 15-62).
Conclusions:
PPF is an uncommon event complicating pancreatitis or pancreatectomy; pancreatic duct disruption is the common link. A step-up approach consisting of minimally invasive techniques treats the majority with surgery needed for refractory sepsis.

Chronic Pancreatitis I: Introduction
Pancreatitis is the inflammation of the pancreas, which occurs when the immune system becomes active and causes swelling, pain, and disruptions in organ function. Pancreatitis can manifest as either an acute or chronic condition.
Acute pancreatitis arises suddenly and lasts for a brief duration, while chronic pancreatitis is a long-term affliction...
