PURPOSE: Small bowel atresia (SBA) presents with variable clinical features depending on anatomical location. We investigated the relationship between atresia location and preterm delivery.
METHODS: We retrospectively reviewed 58 patients who underwent surgery for SBA at two institutions between April 2000 and March 2024. Patients were divided into preterm (<37 weeks, n=28) and term (≥37 weeks, n=30) groups. Clinical characteristics, prenatal findings, anatomical location, and surgical outcomes were compared. A logistic regression analysis identified independent predictors of preterm delivery.
RESULTS: Preterm infants showed lower birth weight (1988±731 g vs. 3062±395 g, p<0.001) and higher rates of prenatal diagnosis (85.7% vs. 60.0%, p=0.040), polyhydramnios (42.9% vs. 13.3%, p=0.018), and bowel dilatation (78.5% vs. 50.0%, p=0.031). The distance from the ligament of Treitz was shorter in preterm infants (31.6±31.5 cm vs. 103.6±39.9 cm, p<0.001). Jejunal atresia was more common in preterm infants (71.4% vs. 6.7%; p<0.001). A strong correlation was observed between birth weight and atresia distance (r=0.63, p<0.001). In a multivariable analysis, proximal atresia was an independent predictor of preterm delivery (adjusted OR 0.79 per 10 cm, 95% CI 0.65-0.96, p=0.018).
CONCLUSION: Proximal SBA was independently associated with preterm delivery. Prenatal identification may facilitate appropriate perinatal management and parental counseling.
