MUC-FIRE: Study protocol for a randomized multicenter open-label controlled trial to show that MUCous FIstula REfeeding reduces the time from enterostomy closure to full enteral feeds

Background: After enterostomy creation, the distal bowel to the ostomy is excluded from the physiologic passage of stool, nutrient uptake, and growth of this intestinal section. Those infants frequently require long-term parenteral nutrition, continued after enterostomy reversal due to the notable diameter discrepancy of the proximal and distal bowel. Previous studies have shown that mucous fistula refeeding (MFR) results in faster weight gain in infants. The aim of the randomized multicenter open-label controlled MUCous FIstula REfeeding ("MUC-FIRE") trial is to demonstrate that MFR between enterostomy creation and reversal reduces the time to full enteral feeds after enterostomy closure compared to controls, resulting in shorter hospital stay and less adverse effects of parenteral nutrition. Methods/Design: A total of 120 infants will be included in the MUC-FIRE trial. Following enterostomy creation, infants will be randomized to either an intervention or a non-intervention group. In the intervention group, perioperative MFR between enterostomy creation and reversal will be performed. The control group receives standard care without MFR.
