Pancreatic necrosis: a scoping review

Abstract

Acute pancreatitis (AP) is a commonly encountered GI diagnosis, accounting for 275,000 hospital admissions annually in the United States alone. Pancreatic necrosis (PN) is the most common complication of AP, and the development of PN is associated with significant morbidity and increased mortality. This expert review evaluates the evidence-based management of symptomatic PN from the era of maximal open pancreatic necrosectomy in the late 1990s though the modern paradigm of minimally invasive and endoscopic interventions. The authors present the retrospective and controlled data behind the "step-up approach" to PN treatment and discuss the application of current society guidance. Evidence based management of PN is characterized by early supportive care, and treatment by minimally invasive intervention when a patient is critically ill or persistently symptomatic. Appropriate choices when intervention is required include percutaneous drainage, minimally invasive surgery, and/or endoscopic treatment. The transition from open maximal necrosectomy to minimally invasive intervention has resulted in improved outcomes for patients, including gains in mortality, significant morbidity, and cost. The ideal precision management strategy for an individual patient remains an area of increasing understanding.
