Post-Pancreaticoduodenectomy Jejunal Perforation and Pancreatic Fistula Caused by Pancreatic Intraductal Stent

Abstract

Postoperative pancreatic fistula (POPF) is a highly dangerous complication following pancreaticoduodenectomy (PD). In this case, a pancreatic intraductal stent was inserted into the pancreatic duct after PD, and the pancreatic intraductal stent punctured the intestinal wall, resulting in POPF. Pancreatic fistula and digestive tract perforation for this reason have not been reported clinically and have certain significance. We present a case of a male patient who underwent PD for a malignant pancreatic tumor. He was admitted for treatment due to recurrent hematemesis and melena postoperatively. Abdominal imaging and biochemical and cytological examinations of ascitic fluid suggest that the patient may have POPF and gastrointestinal perforation. After a series of treatments, the patient's pancreatic fistula and abdominal infection did not improve. After consultation with the patient's family, they decided to refuse further treatment and the patient was discharged. Traditional pancreatic intraductal stents may not necessarily reduce postoperative complications and may also lead to potential adverse reactions.
