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.
