    Abstract:
    BACKGROUND/PURPOSE: therapeutic strategy for meconium-related ileus (MRI) in very-low-birth-weight infants (VLBWs) has not been established. This study aims to clarify the optimum therapeutic strategy for MRI in VLBWs. METHODS: MRI was defined as delayed meconium excretion and microcolon on contrast enema with Gastrografin (diatrizoate acid). Forty-two infants with MRI were treated at our institution between 2009 and 2019, and are reviewed here. They were classified into two groups: in group A (n=21), Gastrografin regurgitated into the dilated intestine during the first or second round of Gastrografin enema (GaE), while in group B (N = 21), Gastrografin did not regurgitate. Laparotomy was indicated if the intestine was perforated, or if abdominal distention was not relieved by two rounds of GaE. RESULTS: in group A, meconium was excreted in all cases within 24 h after GaE, and no cases required laparotomy. In group B, twelve cases (57%) underwent laparotomy (P < 0.01), six cases in this group (29%), showed free air on X-ray images (P < 0.01). The median hospital stay in groups A and B were 89.0 and 136.5 days, respectively (P < 0.05). Overall mortality was 2.4%. CONCLUSIONS: early therapeutic diagnosis by GaE followed by early surgery is suggested as the optimum strategy for MRI in VLBWs.
