Management of Solid Organ Injuries in General Surgery

Non-operative management (NOM) should be the treatment of choice for all hemodynamically stable patients with solid organ injuries, regardless of injury grade, in the absence of other indications for surgery such as peritonitis, bowel evisceration, or hollow viscus injury 1, 2.

Initial Assessment and Diagnostic Approach

Hemodynamic Status Determines Everything

The diagnostic and treatment pathway is fundamentally determined by hemodynamic status 1:

  • Hemodynamically stable patients: CT scan with intravenous contrast is the gold standard for diagnosis and injury grading 1
  • Hemodynamically unstable patients: E-FAST (Extended Focused Assessment with Sonography for Trauma) is rapid for detecting intra-abdominal free fluid, followed by immediate operative management 1

Critical pitfall: Do not delay operative intervention in unstable patients to obtain CT imaging. E-FAST and immediate laparotomy take priority 1.

Classification of Hemodynamic Status

Patients fall into four categories that guide management:

  1. Hemodynamically stable: NOM candidate
  2. Transient responder: May attempt NOM only in well-resourced centers with immediate OR availability, trained surgeons, continuous ICU monitoring, angiography capability, and blood products 1
  3. Hemodynamically unstable: Requires operative management
  4. Non-responder: Immediate operative management mandatory 1

Non-Operative Management Protocol

Patient Selection Criteria

NOM is appropriate for 1, 2:

  • All hemodynamically stable patients with minor (WSES I/AAST I-II), moderate (WSES II/AAST III), and severe (WSES III/AAST IV-V) injuries
  • Absence of peritonitis, bowel evisceration, or other injuries requiring surgery
  • Availability of continuous monitoring, immediate OR access, trained surgeons, angiography, and blood products

Monitoring Requirements

For isolated solid organ injuries 1, 2:

  • Minor injuries (WSES I): May not require ICU admission
  • Moderate injuries (WSES II/AAST III): ICU admission recommended
  • Severe injuries (WSES III/AAST IV-V): ICU admission required

Role of Angiography/Angioembolization (AG/AE)

AG/AE should be utilized in the following scenarios 1:

  • Persistent arterial bleeding after non-hemostatic or damage control procedures
  • Delayed hemorrhage without severe hemodynamic compromise as first-line treatment
  • Hepatic artery pseudoaneurysm to prevent rupture
  • Contrast blush on CT in transient responders or patients with moderate-severe injuries

Important distinction: In pediatric patients, the vast majority do not require AG/AE for CT blush or moderate-severe injuries. AG/AE in children should be reserved for hemodynamically stable patients with signs of persistent hemorrhage not amenable to continued NOM 2.

Operative Management

Indications for Immediate Surgery

Absolute indications 1, 2:

  • Hemodynamic instability (non-responders or unstable patients)
  • Peritonitis
  • Bowel evisceration
  • Impalement
  • Hollow viscus injury
  • NOM failure with persistent bleeding

Surgical Principles

When operating, the primary goals are 1:

  1. Control hemorrhage and bile leak (in liver injuries)
  2. Initiate damage control resuscitation immediately
  3. Avoid major hepatic resections at initial operation—these should only be considered in subsequent operations for debridement of devitalized tissue by experienced surgeons

REBOA (Resuscitative Endovascular Balloon Occlusion of the Aorta) may be used as a bridge to definitive hemorrhage control in unstable patients 1.

Organ-Specific Considerations

Liver Injuries

  • Delayed biliary complications: Symptomatic or infected bilomas require percutaneous drainage 1
  • Post-traumatic biliary fistula: Consider percutaneous drainage combined with endoscopic stenting as first approach 1
  • Delayed surgery: Laparoscopy should be considered to minimize invasiveness 1

Splenic Injuries

  • Pediatric patients: Splenectomy should be avoided in hemodynamically stable children with isolated splenic injury 2
  • Concomitant head trauma: NOM should still be attempted unless the patient is unstable and intra-abdominal bleeding is suspected 2
  • NOM failure: Peaks at 4 hours, then declines over 36 hours; 72.5% of failures occur within the first week 2

Renal Injuries

  • Delayed bleeding risk: Unlike liver injuries where delayed bleeding is rare, continued hemorrhage into the retroperitoneum from kidney injuries is not unusual 3
  • Repeat imaging recommended before discharge for patients with renal injuries, subcapsular hematomas, or recognized extravasation on initial scan 3

Management of Complications

Early Complications (First Week)

  • Intrahepatic abscesses: Percutaneous drainage 1
  • Delayed hemorrhage: AG/AE as first-line treatment if hemodynamically stable 1
  • Symptomatic bilomas: Percutaneous drainage 1

Late Complications

  • Pseudoaneurysms: AG/AE to prevent rupture 1
  • Persistent biliary fistula: Combination of percutaneous drainage and endoscopic techniques 1

Adjunctive Management

Thromboprophylaxis

Mechanical prophylaxis 1:

  • Safe and should be considered in all patients without absolute contraindication

LMWH-based prophylaxis 1:

  • Start as soon as possible following trauma
  • May be safe in selected patients with liver injury treated with NOM
  • For patients on anticoagulants, individualize risk-benefit balance of reversal

Nutrition and Mobilization

  • Early mobilization: Achieve in stable patients 1
  • Enteral feeding: Start as soon as possible in absence of contraindications 1

Special Populations

Pediatric Patients

Key differences from adult management 2:

  • NOM success rate of 95-100% in blunt pediatric trauma
  • Higher-grade injuries can be managed non-operatively more frequently than in adults
  • Splenectomy should be avoided in stable children with isolated splenic injury
  • AG/AE rarely required—most pediatric patients do not need intervention for CT blush
  • Patients >15 years should follow adult AG/AE protocols

Low-Resource Settings

NOM may be considered if 1:

  • Hemodynamic stability maintained
  • No evidence of associated injuries
  • Negative serial physical examinations
  • Negative imaging and blood tests
  • Rapid transfer system available to higher-level care facilities

Critical Pitfalls to Avoid

  1. Do not rely solely on CT grade to determine management—hemodynamic status and clinical assessment are paramount 1

  2. Do not miss hollow viscus injuries—monitor for increasing abdominal pain, distention, vomiting, and signs of inflammation, which may be delayed manifestations 3

  3. Do not discharge patients with high-risk features without repeat imaging—particularly those with subcapsular hematomas, extravasation on initial scan, splenic injuries, or renal injuries 3

  4. Do not attempt NOM in transient responders unless in a well-resourced center with immediate access to all necessary interventions 1

  5. Do not perform major hepatic resections at initial operation—damage control principles apply 1
