Surgical Source Control in Sepsis (SSC 2021): Sepsis with Suspected Source Requiring Control → Identify the Source → Type of Source? → Drainage Source →...
Pathway Overview
16 steps
16 total
Sepsis identified (organ dysfunction + suspected infection). Now determine if there is an anatomic source amenable to intervention. Common sources: intra-abdominal, soft tissue, urinary tract, vascular access, lung.
1) History and exam: Focus on pain location, recent procedures, devices. 2) Imaging: CT with contrast for abdominal/pelvic sources; US for biliary/soft tissue. 3) Labs: Lactate, procalcitonin trending. 4) Consider: Recent surgery, indwelling devices (lines, drains, catheters).
Categorize by intervention type needed: DRAINAGE: Abscess, empyema, obstructed system. DEBRIDEMENT: Necrotic tissue, necrotizing infection. DEVICE REMOVAL: Infected catheter, prosthesis. DEFINITIVE: Perforation repair, resection.
ABSCESS: Intra-abdominal, pelvic, hepatic, splenic, soft tissue. OBSTRUCTED SYSTEM: Biliary (cholangitis), urinary (pyelonephritis with obstruction). EMPYEMA: Pleural space infection. Options: Percutaneous (IR), endoscopic (ERCP), open surgical drainage.
SSC 2021: Source control as soon as medically and logistically practical. For MOST: Within 6-12 hours. EMERGENT (<6h): NSTI, clostridial myonecrosis, bowel infarction, perforation with peritonitis. MAY DELAY: Allow limited resuscitation if hypotensive, but don't delay indefinitely.
Don't wait for stabilization - source control IS the resuscitation. Conditions: NSTI, gas gangrene, bowel perforation/ischemia, ascending cholangitis not responsive to drainage. Continue resuscitation during and after procedure. Consider damage control surgery if unstable.
Choose LEAST INVASIVE option that will achieve source control. Percutaneous/endoscopic preferred over open when possible. Consider: Patient stability, anatomy, available expertise.
CT-guided abscess drainage. ERCP for biliary obstruction. Nephrostomy for obstructed kidney. Advantages: Less invasive, avoid anesthesia risk in unstable patient. Limitations: May not achieve complete source control, may need escalation.
1) Continue resuscitation (may still need vasopressors). 2) Continue antibiotics (duration based on source and adequacy of control). 3) Reassess for adequate source control - if persistent sepsis, re-image. 4) Consider return to OR for 'second look' if damage control. 5) ICU monitoring.
Septic focus eliminated or controlled. Continue antibiotics appropriate duration. Monitor for resolution of organ dysfunction.
Required for: Perforation repair, bowel resection, extensive debridement, failed percutaneous approach. Consider damage control if unstable. Resect/debride all necrotic tissue. Leave abdomen open if ACS risk. Plan return to OR for reassessment.
Standard approach for most abdominal abscesses, complicated UTI, localized infection. Brief resuscitation acceptable: Fluid bolus, initiate vasopressors, start antibiotics. Then proceed to intervention. Don't delay beyond 12 hours.
Select situations only: Infected pancreatic necrosis (prefer day 3-4 walled-off). Stable contained abscess responding to antibiotics. Balance benefits of waiting vs. ongoing sepsis. Close monitoring essential - intervene sooner if deteriorating.
Every hour delay in source control increases mortality in sepsis. Antibiotics alone cannot control an undrained abscess or necrotic tissue. 'Cannot resuscitate a patient who needs surgery' - sometimes source control IS the resuscitation.
NSTI/Fournier's: Aggressive surgical debridement, often multiple returns to OR. PANCREATIC NECROSIS: Consider step-up approach (drain first, then debridement if needed). OSTEOMYELITIS: May need surgical debridement. GAS GANGRENE: Emergency debridement + amputation if needed.
INTRAVASCULAR: Central lines, PICC lines - remove if infected. PROSTHETIC: Joint replacement, vascular graft - may need removal. URINARY: Foley catheter - change or remove. CARDIAC: Pacemaker/ICD - evaluate for extraction if endocarditis.

The Surgical Source Control in Sepsis (SSC 2021) is a emergency clinical algorithm for General Surgery. It provides a structured decision tree to guide clinical decision-making, based on Surviving Sepsis Campaign 2021 International Guidelines.
This algorithm is based on Surviving Sepsis Campaign 2021 International Guidelines (DOI: 10.1007/s00134-021-06506-y).
Known limitations include: Balance between early source control and patient stability requires judgment; Optimal timing varies by source and patient factors; Interventional procedures depend on local expertise; Not all sepsis requires surgical source control; High-risk patients may benefit from damage control approach. Individual patient factors may require deviation from these recommendations.
