What is the best course of action for a patient with Acute Severe Ulcerative Colitis (ASUC) and fulminant colitis, presenting with fever, tachycardia, and active bleeding, who is at high risk of developing peritonitis?

Management of ASUC with Fulminant Colitis and Risk of Peritonitis

This patient requires immediate emergency surgical consultation and preparation for subtotal colectomy with ileostomy, as the presence of fever, tachycardia, and active bleeding in fulminant colitis represents life-threatening systemic toxicity with imminent risk of perforation and generalized peritonitis. 1

Immediate Surgical Indications

Your patient meets criteria for immediate emergency surgery based on the following:

• Generalized peritonitis is an absolute indication for immediate colectomy without attempting further medical therapy 1
• Life-threatening hemorrhage in an unstable patient mandates emergency surgery 1
• Fulminant colitis with marked fever, tachycardia, and active bleeding represents severe systemic toxicity that carries mortality rates of 27-57% if perforation occurs 2
• The overall mortality for ASUC is 1% with optimal care, but rises dramatically in patients >60 years or those with delayed surgery 2

Critical Decision Timeline

If the patient is hemodynamically unstable:

• Proceed directly to emergency surgical exploration according to damage control principles 1
• Subtotal colectomy with ileostomy is the procedure of choice 1
• Do not delay for additional medical therapy 2, 3

If the patient is currently hemodynamically stable but deteriorating:

• Initiate IV methylprednisolone 40-60 mg/day (or hydrocortisone 100 mg four times daily) immediately after fluid resuscitation 4, 2
• Provide aggressive supportive care including IV fluid/electrolyte replacement with potassium supplementation ≥60 mmol/day 1, 4
• Mandatory thromboprophylaxis with low-molecular-weight heparin—active bleeding is NOT a contraindication 1, 4, 2
• Monitor hourly: vital signs, stool frequency, hemodynamic status 4, 2
• If no improvement or any deterioration within 24-48 hours, proceed immediately to colectomy 1, 3

High-Risk Features Demanding Vigilance

Your patient exhibits multiple markers of impending catastrophic complications:

• Temperature of 104°F (40°C) represents marked hyperpyrexia indicating severe systemic inflammatory response 2
• Tachycardia combined with fever meets Truelove and Witts criteria for systemic toxicity 1, 2
• Active bleeding in fulminant colitis raises concern for life-threatening hemorrhage 2
• Toxic megacolon with any peritoneal signs carries >80% likelihood of requiring surgery 3

Absolute Contraindications to Further Medical Therapy

Do not attempt rescue biologic therapy (infliximab/cyclosporine) if any of the following are present:

• Free perforation 1
• Hemodynamic instability with massive hemorrhage 1, 3
• Clinical deterioration with signs of shock 2
• Toxic megacolon with peritoneal signs 3
• Progressive leukocytosis, fever, tachycardia, or worsening abdominal tenderness despite 24-48 hours of medical therapy 3

Multidisciplinary Coordination

• Emergency surgical consultation should begin immediately upon recognition of fulminant features 4
• Daily multidisciplinary team discussion between gastroenterology and surgery is mandatory 1
• Monitor daily: complete blood count, CRP, albumin, electrolytes 1, 4, 2
• Perform unprepared flexible sigmoidoscopy to assess severity and exclude CMV colitis (only if hemodynamically stable) 4

Critical Pitfalls to Avoid

• Delaying surgery beyond 48-72 hours in toxic megacolon substantially increases mortality 2, 3
• Attempting additional rescue therapy in patients with established toxic megacolon and systemic toxicity is contraindicated 3
• Prolonged immunosuppressive therapy before inevitable surgery increases post-operative morbidity and mortality 3
• Underestimating perforation risk in patients with progressive leukocytosis, fever, tachycardia, or worsening abdominal tenderness is dangerous 3
• Do not withhold thromboprophylaxis due to rectal bleeding—this is a critical error 1, 4, 2

Prognosis Context

• With immediate appropriate surgical intervention, mortality can be kept to 1% in specialist centers 2
• Delayed surgery dramatically increases morbidity and mortality 2, 3
• Post-operative morbidity is higher after emergency surgery compared to elective surgery, but delaying necessary surgery worsens outcomes further 3
• Approximately 34% of fulminant colitis patients require surgery, though modern biologic rescue can reduce this to 20-30% in appropriately selected stable patients 3

Your patient's presentation with fulminant features and high risk of peritonitis places them in the highest mortality category unless immediate surgical intervention is pursued. 2, 3
