Treatment of Enterocolitis

The treatment of enterocolitis requires a targeted approach based on the specific type and severity of the disease, with initial management including IV fluid resuscitation, broad-spectrum antibiotics, and bowel rest for severe cases. 1

Diagnosis and Initial Evaluation

Before initiating treatment, proper diagnosis is essential:

  • Stool studies for infectious pathogens (C. difficile, Salmonella, E. coli, Campylobacter)
  • Laboratory tests: complete blood count, electrolytes, inflammatory markers (CRP)
  • Endoscopic evaluation for grade >1 symptoms
  • Contrast-enhanced CT, especially in immunocompromised patients 1

Treatment Algorithm Based on Severity and Type

Mild to Moderate Disease

  • Oral rehydration therapy
  • Dietary modifications
  • Symptomatic treatment with loperamide for non-bloody diarrhea
  • For parasitic infections: TMP-SMZ 160mg/800mg bid or ciprofloxacin 500mg bid for 7 days 1

Severe Disease

  1. Hospitalization required for grade 3-4 enterocolitis
  2. Aggressive IV fluid resuscitation
  3. Broad-spectrum antibiotics:
    • Monotherapy options: piperacillin-tazobactam, carbapenems (imipenem or meropenem)
    • Combination therapy: cefepime/ceftazidime plus metronidazole 2, 1
  4. Bowel rest with nasogastric decompression
  5. Specific treatments based on etiology:

For Ulcerative Colitis Enterocolitis

  • IV corticosteroids: methylprednisolone 60 mg/24h or hydrocortisone 100 mg four times daily
  • For steroid-refractory disease: consider ciclosporin, tacrolimus, or infliximab
  • Subcutaneous prophylactic low-molecular-weight heparin to reduce thromboembolism risk 2

For Neutropenic Enterocolitis

  • G-CSF administration
  • Surgical intervention only for perforation, persistent bleeding, or clinical deterioration 1

For Immune Checkpoint Inhibitor Enterocolitis

  • Corticosteroids (1 mg/kg/day prednisone) until symptoms improve to Grade 1
  • Infliximab (5 mg/kg IV) or vedolizumab for steroid-refractory cases 1

For CMV Enteritis

  • Ganciclovir 5 mg/kg bid IV for 2-3 weeks 1

For Necrotizing Enterocolitis (primarily in premature infants)

  • Broad-spectrum antibiotics
  • Bowel rest
  • Peritoneal drainage or laparotomy with bowel resection when perforation occurs 2, 3

Monitoring and Follow-up

  • Daily clinical assessment with vital signs, fluid status, and electrolytes
  • Serial abdominal examinations
  • Follow-up imaging if clinical deterioration occurs
  • Monitor response to steroids within 72 hours for immune-related enterocolitis 1

Special Considerations

Antibiotic Selection

For complicated intra-abdominal infections, appropriate empiric therapy includes:

  • Carbapenems (imipenem or meropenem)
  • Piperacillin-tazobactam
  • Extended-spectrum cephalosporin (cefotaxime, ceftriaxone, ceftazidime, or cefepime) with metronidazole 2

Surgical Management

  • Early surgical consultation for complicated cases
  • Emergency surgery for perforation, persistent bleeding, or clinical deterioration
  • In very low birth weight neonates with necrotizing enterocolitis, peritoneal drainage may be used instead of immediate operation 2

Complications to Monitor

  • Neutropenia increases risk of rapid progression to ischemia, necrosis, and perforation
  • Progression to toxic megacolon, perforation, and multisystem organ failure
  • CT findings of bowel wall thickening >10 mm indicate higher mortality risk (60%) 1

Prevention Strategies for Necrotizing Enterocolitis

  • Use of antenatal corticosteroids to enhance fetal maturation if preterm delivery is likely
  • Breast milk feeding when possible
  • Early initiation of trophic feeds with judicious advancement
  • Prophylactic probiotics may play a role in prevention 3
