Factors associated with enteral autonomy after reanastomosis in infants with intestinal failure and ostomy: A descriptive cohort study.

ABSTRACT

BACKGROUND: To determine variables associated with outcomes in infants with intestinal failure (IF) and ostomy following reanastomosis (RA). METHODS: A single-center, descriptive cohort study of 120 infants with IF and a stoma from January 2011 to December 2020 with subsequent RA during initial hospitalization. The primary outcome was achievement of enteral autonomy (EA) following RA. Other outcomes were duration of hospital stay, and mortality. Penalized logistic regression and linear regression were used for data analysis. RESULTS: The median gestational age was 26 weeks, and the median birth weight was 890 g. Three infants died. The median duration between ostomy creation and RA was 80 days (interquartile range; 62.5, 100.5). For each additional day of discontinuity, the odds of EA decreased by 2% (odds ratio [OR] = 0.980; 95% confidence interval [CI] 0.962, 0.999; P = 0.038), and death increased by 4.2% (OR = 1.042; 95% CI 1.010, 1.075; P = 0.009). For each additional mL/kg/day of enteral feeds at RA, the odds of EA increased by 7.5% (OR = 1.075; 95% CI 1.027, 1.126, P = 0.002) and duration of hospital stay decreased by 0.35 days (slope coefficient = -0.351; 95% CI -0.540, -0.163; P < 0.001). CONCLUSION: Shorter duration of intestinal discontinuity and enteral nutrition before RA could positively influence EA and duration of stay in infants with IF and ostomy following RA.
