Management of Omental Infarction
Initial Management Recommendation
Conservative management with analgesics and observation for 24-48 hours is the recommended first-line approach for omental infarction, with surgical intervention reserved for patients who fail conservative treatment or have persistent symptoms. 1, 2
Diagnostic Confirmation
- CT imaging is essential to confirm the diagnosis and avoid unnecessary surgery, as omental infarction produces characteristic radiological findings including a focal area of fat stranding, often with a "whirl sign" in cases of torsion 1, 3, 4
- The diagnosis can occur at any abdominal location (right iliac fossa, right upper quadrant, epigastric area, or even left-sided), though right-sided presentation is most common 1, 2
Conservative Management Protocol
Initial conservative management should include:
- Analgesics for pain control (NSAIDs or opioids as needed) 1, 2
- Observation period of 24-48 hours with serial abdominal examinations 1
- NPO or clear liquids initially, advancing diet as tolerated 2
- Average hospital stay of 3-4 days for successful conservative management 1
Success rate: Approximately 69% of patients respond successfully to conservative management without requiring surgery 1
Indications for Surgical Intervention
Proceed to laparoscopic omentectomy if:
- Symptoms persist or worsen despite 24-48 hours of conservative management 1, 2
- Patient develops peritoneal signs suggesting complications 3
- Severe, refractory pain that significantly impacts quality of life 1
Surgical Approach When Indicated
- Laparoscopic omentectomy is the preferred surgical technique when intervention is necessary, offering diagnostic confirmation and definitive treatment 1, 3
- Resection of the infarcted omental segment should be performed to prevent ongoing symptoms and potential complications 3
- Even if omental infarction is discovered incidentally during laparoscopy for presumed appendicitis, resection can be considered to expedite symptom resolution 5, 3
Clinical Outcomes
- No significant morbidity or mortality reported with either conservative or surgical management 1
- The condition is generally self-limited when managed conservatively 2, 4
- Surgical management may expedite symptom resolution in refractory cases 5, 3
Key Clinical Pitfalls to Avoid
- Do not rush to surgery without adequate imaging - omental infarction frequently mimics appendicitis, cholecystitis, or diverticulitis, and unnecessary operations can be avoided with proper CT diagnosis 2, 4
- Do not dismiss the diagnosis based on location alone - while right-sided pain is most common, omental infarction can occur anywhere in the abdomen 2
- Do not continue conservative management beyond 48 hours if symptoms are worsening - persistent or progressive pain warrants surgical intervention 1
