Mucous fistula refeeding in neonates with enterostomies.

Background/purpose: Neonates with intestinal pathology may require staged surgery with creation of an enterostomy and mucous fistula (MF). Refeeding (MFR) of ostomy output may minimize fluid and electrolyte losses and reduce dependence on parenteral nutrition (PN), though a paucity of evidence exists to support this practice. The purpose of this study was to assess the outcomes of infants undergoing MFR and document associated complications.

Methods: With REB approval, infants with intestinal failure undergoing MFR between January 2000 and December 2012 were identified. A chart review was conducted and relevant data were collected. Descriptive statistics were used.

Results: Twenty-three neonates underwent MFR. Mean gestational age and birth weight were 35weeks and 2416grams. Pathologies included intestinal atresia (n=12), necrotizing enterocolitis (n=5), meconium ileus (n=4), and other (n=6). Seven patients were able to wean from PN. Four patients had complications: 3 had perforation of the MF, 1 had bleeding. Four patients died, with one death directly attributable to MFR.

Conclusions: In this cohort MF refeeding was associated with significant complications and ongoing PN dependence. With advances in intestinal rehabilitation and PN, the benefit of MF refeeding must be weighed against the potential complications.
