The Importance of the ileocecal valve and colon in achieving intestinal independence in infants with short bowel syndrome

Purpose: Infants with short bowel syndrome (SBS) wean from parenteral nutrition (PN) support at variable rates. Small bowel length is a predictor, but the importance of the ileocecal valve (ICV) and colon are unclear. We aim to determine if the ICV and/or colon predict enteral autonomy. Methods: Infants from a single intestinal rehabilitation program were retrospectively reviewed. Etiology of SBS, intestinal anatomy, and duration of nutritional support were collected for three years. The primary outcome was time to full enteral nutrition. ANCOVA and Cox proportional hazards model were used, with p < 0.05 significant. Results: 55 infants with SBS were included. After accounting for the effect of small bowel, PN duration was shorter for infants with the ICV compared to those without (mean 218 vs. 538 days, p = 0.003), and had a more significant effect on infants with <50% of small bowel. Increased small bowel length was a positive predictor of weaning. Patients with <50% of colon spent less time on PN with the ICV, compared to without (mean 220 vs 715 days, p = 0.009). Conclusions: Preservation of the ICV was associated with shorter duration of PN support, while colon was not. Small bowel length is a positive predictor of enteral autonomy.

Automated summary

Preservation of the ileocecal valve (ICV) is associated with a shorter duration of parenteral nutrition (PN) support in infants with short bowel syndrome (SBS), while the colon does not play a significant role. Small bowel length is a positive predictor of enteral autonomy.
