Acute Pancreatitis Surgical Timing - IAP/APA Guidelines: Severe Acute Pancreatitis with Necrosis → Severity Assessment → Infected Necrosis? → Sterile Ne...

Pathway Overview

12 steps

Algorithm Steps

12 total

  1. 01Start

    Severe Acute Pancreatitis with Necrosis

    CT-confirmed pancreatic/peripancreatic necrosis

  2. 02Action

    Severity Assessment

    Atlanta classification, organ failure

    • Persistent organ failure >48h = severe
    • CT severity index
    • APACHE II, BISAP scores
  3. 03Decision

    Infected Necrosis?

    • Gas in collection (CT)
    • FNA showing bacteria/fungi
    • Clinical deterioration/sepsis
  4. 04Action

    Sterile Necrosis

    Conservative management usually

  5. 05Action

    Conservative Management

    ICU care, nutrition, wait

    • Enteral nutrition (NJ preferred)
    • No role for prophylactic antibiotics
    • Repeat imaging at 7-10 days
    • Intervene only if infected or symptomatic
  6. 06End

    Resolution & Follow-up

    Manage exocrine/endocrine insufficiency, cholecystectomy if biliary

  7. 07Action

    Infected Necrosis

    Intervention needed

  8. 08Decision

    Timing of Intervention

    • Delay until WON (≥4 weeks)
    • Bridge with antibiotics, nutrition
    • Earlier if septic/deteriorating
  9. 09Action

    Step-Up Approach

    Start minimally invasive

    • 1. Percutaneous/endoscopic drainage
    • 2. If fails: video-assisted debridement
    • 3. Open necrosectomy only if needed
  10. 10Action

    Percutaneous/EUS Drainage

    First step of intervention

    • CT-guided drain for PFC
    • EUS-guided for WON access
    • Multiple drains may be needed
  11. 11Action

    Minimally Invasive Debridement

    If drainage insufficient

    • VARD (video-assisted)
    • DEN (direct endoscopic necrosectomy)
    • Transgastric or retroperitoneal
  12. 12Action

    Open Necrosectomy

    Last resort

    • If minimally invasive fails
    • Severe sepsis requiring source control
    • Higher morbidity/mortality

Clinical Safety Information

Clinical Decision Support — Not a Substitute for Clinical Judgment

Individual patient factors may require deviation from these recommendations.

Known Limitations

  • Step-up approach now standard over primary necrosectomy
  • Timing of intervention depends on walled-off necrosis formation
  • Infected necrosis is primary indication for intervention
  • Multidisciplinary expertise essential
