The risk factors for cholestasis in patients with duodenal atresia in a single institutional cohort.

Purpose The etiology of cholestasis in neonates is associated with several factors including gastrointestinal disease and surgery. We aimed to identify the potential risk factors for perioperative cholestasis in patients with duodenal atresia and determine specific cutoff values for the risk factors. Methods This retrospective cohort study included 76 neonates diagnosed with duodenal atresia surgically treated during the neonatal period at our institution between January 1990 and March 2017. The neonates were categorized into two groups: those with and without cholestasis. Univariate and multivariate analyses were performed to identify the possible risk factors for cholestasis. Results Among the 76 neonates with duodenal atresia, 21 (27%) developed cholestasis. The duration of total parenteral nutrition was identified as a risk factor in univariate analysis; however, it was not an independent risk factor for cholestasis. Gestational age and highest C-reactive protein (CRP) values were independent risk factors, with adjusted odds ratios of 0.53 and 1.25, respectively. To predict the occurrence of cholestasis, the cutoff value for gestational age was 35.0 weeks, and highest CRP value was 2.4 mg/dL. Conclusions The occurrence of cholestasis in patients with duodenal atresia was associated with preterm delivery and severity of the inflammatory response during the perioperative period.
