Interventional strategies in infected necrotizing pancreatitis: Indications, timing, and outcomes

Acute pancreatitis (AP) is one of the most common gastrointestinal diseases and remains a life-threatening condition. Although AP resolves to restitutio ad integrum in approximately 80% of patients, it can progress to necrotizing pancreatitis (NP). NP is associated with superinfection in a third of patients, leading to an increase in mortality rate of up to 40%. Accurate and early diagnosis of NP and associated complications, as well as state-of-the-art therapy are essential to improve patient prognoses. The emerging role of endoscopy and recent trials on multidisciplinary management of NP established the step-up approach . This approach starts with endoscopic interventions and can be escalated to other interventional and ultimately surgical procedures if required. Studies showed that this approach decreases the incidence of new multiple-organ failure as well as the risk of interventional complications. However, the optimal interventional sequence and timing of interventional procedures remain controversial. This review aims to summarize the indications, timing, and treatment outcomes for infected NP and to provide guidance on multidisciplinary decision-making.

Automated summary

Acute pancreatitis is a common gastrointestinal disease and can progress to necrotizing pancreatitis, which is associated with infection and increased mortality. Early diagnosis and treatment are crucial for improving patient outcomes. The step-up approach, which includes endoscopic interventions, has shown to decrease multiple-organ failure and intervention-related complications. However, the optimal sequence and timing of interventions remain controversial.
