Background: Necrotizing enterocolitis is the most common gastrointestinal emergency in the neonates and its course is often fulminating with progressive lethargy. The purpose of this study is to determine the period of NP0(non per os) treatment in the patients with neonatal necrotizing enterocolitis. Matenal and methods: For determining the normal range of CT(Computerized tomography) attenuation coefficients of urine from normal neonates, 60 normal neonates participated in this study. And urine specimens from 16 patients with stage IIB necrotizing enerocolitis were obtained 8-12 hours after the instillation of iohexol enterally. The attenuation coefficients of each urine specimen were determined with CT. Periodic examinations were performed at an interval of two days. As soon as the values of attenuation coefficients reached the normal range, we discontinued NPO treatment. Results: The mean period of NPO treatment of 16 patients with stage IIB necrotizing enterocolitis was 11.1 days. The NPO period of 6 patients were 8 days, two were 10 days, four were 12 days, one was 14 days and three were 16 days. Conclusion: By means of this study, we were able to determine the period of NPO treatment on a case by case basis. The authors think that CT examination of the obtained urine after the instillation of iohexol may be a good method to determine the period of NPO treatment.
