While over the past several decades mortality after pancreatic surgery has decreased to <5%, postoperative morbidity remains remarkably high, ranging from 15% to 65%. The development of a postoperative pancreatic fistula (POPF) is a significant contributor to morbidity in patients undergoing pancreatic surgery. POPF can lead to life-threatening conditions such as intra-abdominal abscess, uncontrolled hemorrhage, sepsis, and death. Rates of POPF have not significantly changed over time, despite the introduction of multiple technical and pharmacologic interventions aimed at their treatment and prevention. Unfortunately, there are few POPF experimental models that have been described in the literature and existing models are unable to reliably reproduce the clinical sequelae of POPF, limiting the development of new methods to prevent and treat POPF. Herein, we describe a new rat experimental model that reliably creates a POPF via transection of the common pancreatic duct.
