Yes, feeding jejunostomy can and should be placed with simultaneous peri-operative chemotherapy in malnourished patients to provide nutritional support
In malnourished patients undergoing major upper gastrointestinal or pancreatic cancer surgery with peri-operative chemotherapy, feeding jejunostomy placement is specifically recommended to enable concurrent nutritional optimization during treatment. This approach is supported by the most recent ESPEN guidelines and clinical evidence demonstrating improved treatment completion rates and outcomes 1.
The Evidence-Based Approach
When to Place Feeding Jejunostomy
Place feeding jejunostomy at the time of staging laparoscopy or initial surgery in patients who meet any of these criteria:
- Weight loss >10-15% in the past 6 months
- BMI <18.5 kg/m²
- Nutritional Risk Screening (NRS-2002) score ≥3
- Expected inability to maintain >50% oral intake for >7 days
- Dysphagia or passage obstruction
- Planned neoadjuvant chemotherapy for esophageal, gastric, or pancreatic cancer 2, 1
Timing and Implementation Strategy
The feeding jejunostomy should be placed BEFORE starting neoadjuvant chemotherapy, ideally during staging laparoscopy. This allows nutritional support to begin immediately when chemotherapy starts, preventing further nutritional deterioration 3, 4.
Start enteral feeding within 24 hours of jejunostomy placement at a low rate (10-20 mL/h initially), gradually increasing over 5-7 days as tolerated to reach nutritional targets of 30 kcal/kg and 1.0-1.5 g protein/kg body weight 2, 1.
Critical Safety Considerations for Refeeding Syndrome
In severely malnourished patients, start at 10-30 mL/h and increase cautiously while monitoring electrolytes (phosphate, potassium, magnesium) and thiamine levels daily for the first week. This prevents life-threatening refeeding syndrome, which is a major risk when rapidly feeding malnourished patients 1.
Clinical Benefits During Chemotherapy
The evidence demonstrates that feeding jejunostomy during peri-operative chemotherapy:
- Improves chemotherapy completion rates: 96% vs 81.6% in patients without jejunostomy 3
- Maintains weight and body composition during neoadjuvant treatment 5, 6
- Enables continuation of chemotherapy when oral intake becomes inadequate 7
- Reduces major postoperative complications when nutritional parameters are optimized 8
Specific Guideline Recommendations
The 2025 ESPEN Surgery Guidelines (Grade B recommendation) state that in patients with malnutrition and/or high metabolic risk, intraoperative placement of nasojejunal tube or feeding jejunostomy should be considered for all candidates undergoing major upper gastrointestinal and pancreatic surgery 1.
For oncology patients specifically, the 2009 ESPEN Oncology Guidelines confirm that routine PN during chemotherapy is NOT recommended, BUT if patients are malnourished or facing >1 week of inadequate intake and enteral support is feasible, enteral nutrition (including via jejunostomy) IS recommended (Grade C) 9.
Practical Implementation Algorithm
Step 1: Assess nutritional risk at cancer diagnosis using NRS-2002 or similar validated tool
Step 2: If high risk (score ≥3) or malnourished, schedule feeding jejunostomy placement at staging laparoscopy
Step 3: Begin enteral feeding 24 hours post-placement at 10-30 mL/h
Step 4: Monitor electrolytes daily for first week; increase feeding rate by 10-20 mL/h every 1-2 days as tolerated
Step 5: Start chemotherapy once feeding tolerance established (typically 3-7 days)
Step 6: Continue jejunostomy feeding throughout chemotherapy and into postoperative period
Step 7: Maintain feeding until patient achieves >60% oral intake consistently 2
Common Pitfalls to Avoid
Do not delay jejunostomy placement until after chemotherapy has started and malnutrition has worsened. Early placement (at staging) allows immediate nutritional support 3, 4.
Do not advance feeding too rapidly in severely malnourished patients—this causes refeeding syndrome with potentially fatal electrolyte shifts 1.
Do not use parenteral nutrition as first-line when enteral access is available. Enteral feeding via jejunostomy is preferred over PN during chemotherapy 9, 10.
Do not remove the jejunostomy early. Keep it in place through the entire peri-operative period and potentially for home enteral nutrition if needed postoperatively 2, 11.
Complication Rates and Management
Feeding jejunostomy complications occur in 1.5-6% of cases and include tube dislodgement (most common), blockage, and rarely bowel ischemia from rapid feeding 2, 1. Most complications are managed at bedside with tube replacement. The benefits of maintained nutrition during chemotherapy far outweigh these risks in malnourished patients 5, 3.
The key principle: feeding jejunostomy enables simultaneous nutritional optimization and chemotherapy delivery, improving treatment completion and surgical outcomes in malnourished cancer patients.
