Management of acute necrotizing pancreatitis with duodenal fistula

Abstract

Severe acute pancreatitis (SAP) is often accompanied by severe infected pancreatic necrosis. Gastrointestinal fistula is a common complication during the infectious period of SAP, with the incidence of duodenal fistula coming in second place after colon fistula and a high mortality rate. Percutaneous catheter drainage (PCD) is the most commonly used surgical technique for necrotizing infection in SAP. However, the traditional PCD method cannot achieve adequate source control in SAP necrotizing infection patients with gastrointestinal fistulas. This report describes a case of SAP necrotizing infection complicated with a duodenal fistula treated with trocar-assisted percutaneous abscess drainage combined with manual irrigation. After treatment with double-lumen catheter irrigation and drainage combined with manual irrigation and other standards of care for SAP, the patient’s infection symptoms were gradually relieved. A review of abdominal computed tomography and gastrointestinal radiography showed that the intra-abdominal infection was gradually relieved, and the duodenal fistula was completely healed.
