This condition is often associated with chronic pancreatitis, pancreatic trauma, or pseudocyst rupture. Because of its rarity and ill-defined clinical presentation, pancreatic ascites is often a diagnostic and therapeutic challenge in clinical practice. The current diagnostic criteria include an amylase level >1000 mg/dL, a protein level >3 g/dL, and a serum ascites albumin gradient <1.1 g/dL. The clinical features vary, but may include progressive abdominal distension, diffuse abdominal pain, weight loss and peritonitis. The management of pancreatic ascites remains controversial, and there is no consensus regarding the optimal approach. Conservative medical management, which includes nutritional support, pain control, therapeutic paracentesis and the use of somatostatin analogs, has been associated with a high failure rate and significant morbidity. Interventional therapies, such as surgery and endoscopic transpapillary stenting, have shown more promising outcomes. However, the choice between these methods is still debated, with some advocating for endoscopic approaches, because of their minimally invasive nature and reduced morbidity compared with surgical options. Endoscopic approaches remain underutilized in practice, probably because of the need for repeated interventions, the potential risks associated with endoscopic retrograde cholangiopancreatography, or a lack of skilled personnel.
