Abstract

Objective:The aim of this study was to determine the relationship of superior mesenteric artery (SMA) blood flow and intestinal motility with feeding tolerance in infants with gastroschisis. Study Design: This was a prospective observational cohort study of 23 infants with gastroschisis. Magnetic resonance images were obtained at abdominal wall closure, initiation of feeds, and full feeds. Motility and SMA flow data were correlated with feeding tolerance. Result:All infants had abnormal motility, and most continued with abnormal motility despite achieving full feeds. Increased SMA flow at the time of abdominal wall closure was found to be significantly related to the earlier achievement of full feeds (ρ = –0.45, p = 0.05) and trended towards earlier initiation of feeds (ρ = –0.36, p = 0.13), shorter parenteral nutrition days (ρ = –0.42, p = 0.07), and earlier discharge (ρ = –0.41, p = 0.08). Conclusion: Increased SMA blood flow at the time of abdominal wall closure is positively correlated with feeding tolerance, suggesting the importance of initial intestinal perfusion in the pathophysiology for feeding intolerance and intestinal dysmotility in gastroschisis.
