Pathway Overview
16 steps
Algorithm Steps
16 total
01Start 02Action Recognise Neutropenic Enterocolitis
Neutropenia plus abdominal pain, often right lower quadrant. Fever may be absent.
- Neutrophils <0.5 × 10^9/L, or <1.0 × 10^9/L and expected to fall below 0.5 × 10^9/L within 48 h
- Fever ≥38.0 °C; may be absent in older patients or with corticosteroids
- Abdominal pain (often right lower quadrant), distension, diarrhoea (may be bloody), nausea or vomiting
- Rebound tenderness, guarding or absent bowel sounds suggest severe disease
- Highest risk: acute leukaemia, high-dose cytarabine with an anthracycline, high-dose chemotherapy
- Also after taxanes, fluorouracil, other cytotoxics or abdominal radiotherapy, usually at the neutrophil nadir
03Warning Neutropenia: No Rectal Procedures or Antimotility Drugs
Adults only. Children: use the paediatric oncology protocol and doses.
- No rectal examination, rectal temperature, enema, suppository or endoscopy: risk of infection, bleeding and perforation
- No loperamide or other antimotility drugs; limit opioids to what controls pain: they can worsen ileus and mask deterioration
- These cautions must not delay antibiotics or surgical review
04Action Sepsis Assessment and Cultures
Follow the local sepsis pathway. Take cultures, then give antibiotics without waiting for results or CT.
- 2 sets of blood cultures: 1 from each lumen of a central line and 1 peripheral
- FBC, EUC, LFTs, lactate, coagulation, group and hold
- Stool for C. difficile testing and culture if diarrhoea
- IV access, oxygen if needed; fluid resuscitation if hypotensive or lactate >2 mmol/L
- Lactate >2 mmol/L: repeat in 2 h; persistently high: ICU review
05Warning Before Antibiotics: Allergy, Valproate, Kidney Function
Check these fast. Do not delay the first dose.
- Penicillin allergy: non-severe, cefepime + metronidazole; anaphylaxis, meropenem or a non-cross-reactive cephalosporin + metronidazole; SCAR, expert advice (if delayed: aztreonam or ciprofloxacin + vancomycin + metronidazole)
- Takes valproate: avoid meropenem (lowers valproate levels; seizures). Use another option
- Kidney impairment: adjust doses after the first dose (pharmacist advice)
06Action Empiric IV Antibiotics Now (Adult Doses)
Within 1 h if sepsis or shock; otherwise within 1 to 2 h. Doses for normal kidney and liver function.
- Piperacillin-tazobactam 4.5 g (4 g/0.5 g) IV 6-hourly, OR
- Cefepime 2 g IV 8-hourly PLUS metronidazole 500 mg IV 12-hourly, OR
- Meropenem 1 g IV 8-hourly (penicillin anaphylaxis, or MDRO risk with sepsis)
- Piperacillin-tazobactam and meropenem already cover anaerobes: do not add metronidazole
- Add vancomycin for Gram-positive in blood culture, or sepsis with MRSA risk, line or skin infection or severe mucositis: 25-30 mg/kg IV load (max 3 g), then 15-20 mg/kg (max 2 g) 12-hourly, adjusted to levels
- Septic shock: consider adding an aminoglycoside (eviQ ID 123 Table 1); follow local antibiogram
- Known VRE colonisation: infectious diseases advice
07Action CT Abdomen and Pelvis
Confirms the diagnosis and looks for perforation. Do not delay antibiotics for imaging.
- CT with IV contrast if kidney function allows; ultrasound is an alternative
- Diagnostic: bowel wall thickening >4 mm over >30 mm length, often caecum, ascending colon or terminal ileum
- Severe signs: pneumatosis, free gas (perforation), abscess, wall >10 mm
- Other findings: fat stranding, ascites
- Consider other causes: appendicitis, C. difficile colitis, CMV colitis, immune checkpoint inhibitor colitis, graft-versus-host disease after allogeneic transplant
08Decision Complicated or High-Risk Disease?
Perforation, peritonitis, abscess, pneumatosis, uncontrolled bleeding, septic shock or bowel wall >10 mm
- If Yes
- Yes: complicated or high risk
09Action Complicated or High Risk: Urgent Surgical and ICU Review
Call the surgical team and ICU now. Continue antibiotics and supportive care (next step).
- Septic shock: resuscitate per sepsis pathway; ICU for vasopressors
- Free perforation, bowel necrosis or uncontrolled bleeding: emergency surgery; do not wait for neutrophil recovery
- Correct platelets and clotting and withhold anticoagulants and antiplatelets before surgery or drainage, but do not delay emergency surgery
- Abscess: discuss drainage with surgery and radiology
10Action Supportive Care (All Patients)
Most patients recover with medical care. Tell the surgical team early in every case.
- Bowel rest (nil by mouth) if pain is severe, distension, ileus or vomiting; otherwise bland diet as tolerated
- NG tube if distended or vomiting
- IV fluids and electrolyte replacement
- Regular analgesia; review often (see cautions)
- Parenteral nutrition if prolonged bowel rest is expected
- Transfuse platelets and red cells for bleeding or per local thresholds
- G-CSF: not routine; haematology decision case by case
- Fever despite antibiotics after 4-7 days: discuss empirical antifungal therapy with haematology or infectious diseases
11Action C. difficile Positive: Add Oral Treatment
C. difficile can coexist with neutropenic enterocolitis. Test every patient with diarrhoea.
- Adult: oral vancomycin 125 mg 6-hourly for 10 days, OR oral fidaxomicin 200 mg 12-hourly for 10 days
- Fulminant (shock, ileus or megacolon): vancomycin 500 mg orally or by NG tube 6-hourly PLUS metronidazole 500 mg IV 8-hourly; infectious diseases and surgical advice
- Unstable with high suspicion: start treatment before the result
- Rectal vancomycin only on infectious diseases advice (neutropenia)
- Continue the neutropenic enterocolitis antibiotics; stop only other antibiotics that are not needed
12Action Close Monitoring
Frequent review. Worsening at any time: urgent surgical review.
- Observations every 30 min for the first 2 h, then hourly for 4 h, then per local policy
- Senior clinical and surgical abdominal review at least daily, more often if unstable
- Daily FBC, EUC; lactate if septic
- Repeat CT if pain, distension, bleeding or sepsis worsens
- Watch for peritonism, rising lactate, shock, bleeding
13Decision Surgery Indicated?
Perforation, uncontrolled bleeding despite correction of platelets and clotting, bowel necrosis, or deterioration despite full medical care
- If Yes
14Action Surgery Indicated: Operate Without Delay
For perforation, necrosis, uncontrolled bleeding or deterioration. Correct platelets and clotting, but low counts are not a reason to delay.
- Correct platelets and clotting before and during surgery; withhold anticoagulants and antiplatelets (haematology advice on reversal)
- Resect necrotic bowel (often right hemicolectomy)
- Two-stage procedure (stoma) preferred over primary anastomosis
- Send tissue for bacterial and fungal culture and histology
15Action Improving: Recovery and Diet
No surgery needed and improving, or after surgery. Not improving: continue supportive care and daily surgical review.
- Advance diet slowly as pain and distension settle
- Continue IV antibiotics until clinical signs resolve and neutrophils ≥0.5 × 10^9/L
- Then switch to oral only if eating and absorbing; length of therapy: treating team
- Repeat CT if symptoms persist
16Outcome Neutropenic Enterocolitis Resolved
Plan the next chemotherapy cycle with the treating haematologist or oncologist; it can recur.

Applicable Regions
AUNZUSEUGlobal
AU: Antibiotic choice and doses follow eviQ ID 123 (V7, July 2026), adapted from the 2024 Australasian consensus guidelines for neutropenic fever. Neutrophils in × 10^9/L; fever is a single temperature of 38.0 °C or higher.
EU: AGIHO/DGHO 2017 recommends piperacillin-tazobactam, imipenem-cilastatin or meropenem and a bland diet with hydration and analgesia.
US: IDSA 2010 advises piperacillin-tazobactam, a carbapenem, or an antipseudomonal cephalosporin plus metronidazole for neutropenic enterocolitis, and defines neutropenia as ANC <500 cells/mm3.
