Invasive intervention timing for infected necrotizing pancreatitis: Late invasive intervention is not late for collection

With the advance of invasive interventions, the treatment model for infected necrotizing pancreatitis (INP) has shifted from open surgery to the step-up minimally invasive treatment. Late intervention, originating from the open surgery era, has been questioned in the minimally invasive period. With the emergence of new high-quality evidence about the timing for intervention, it seems to be increasingly apparent that, even in the age of minimal invasiveness, “late intervention” waiting for the necrotic collections to be encapsulated is still necessary. This opinion review mainly discusses the intervention timing for INP.
