Predictive Indicators for Necrotizing Enterocolitis With the Presence of Portal Venous Gas and Outcomes of Surgical Interventions.

ABSTRACT: Objectives: Portal venous gas (PVG) was an important clinical sign in stage II or III necrotizing enterocolitis (NEC) in preterm neonates. Not a proper predictive indicator was found to predict the diseases (NEC with the presence of PVG) up to now. There is a need to put forward predictive indicators and compare the predictive effects among them. Methods: We conducted a retrospective study of preterm neonates with NEC-PVG (n = 61) or NEC-non PVG (n = 62) from 2014 to 2021. Predictive indicators were put forward and determined by receiver operating characteristic curve analysis. An analysis of the surgical interventions and their outcomes was performed. Results: The incidence rate of NEC among preterm neonates was 4.99%; surgical and conservative interventions accounted for 20.47 and 75.07%, and the mortality rate was 0.03%. The composition ratio of shock in the NEC-PVG group increased 13.2% (P = 0.029). C-reactive protein, fibrinogen degradation product, and blood glucose had better predictive effects in the predictive indicators (P < 0.05). Intestinal necrosis and subependymal hemorrhage in the outcomes of surgical interventions had a strong relationship with the presence of PVG in NEC II/III (P < 0.05). Conclusion: Early and reasonable use of antibiotics, improvement of coagulation function, rectification of acidosis, and decreased blood glucose could cut down the occurrence of the disease (NEC with the presence of PVG). Except for subependymal hemorrhage and intestinal necrosis, NEC with the presence of PVG did not increase the occurrence of other outcomes after surgery.

Project description:Necrotizing enterocolitis (NEC) is one of the most common and lethal gastrointestinal diseases in preterm infants. Early recognition of infants in need for surgical intervention might enable early intervention. In this multicenter case-control study, performed in nine neonatal intensive care units, preterm born infants (< 30 weeks of gestation) diagnosed with NEC (stage ≥ IIA) between October 2014 and August 2017 were divided into two groups: (1) medical (conservative treatment) and (2) surgical NEC (sNEC). Perinatal, clinical, and laboratory parameters were collected daily up to clinical onset of NEC. Univariate and multivariate logistic regression analyses were applied to identify potential predictors for sNEC. In total, 73 preterm infants with NEC (41 surgical and 32 medical NEC) were included. A low gestational age (p value, adjusted odds ratio [95%CI]; 0.001, 0.91 [0.86-0.96]), no maternal corticosteroid administration (0.025, 0.19 [0.04-0.82]), early onset of NEC (0.003, 0.85 [0.77-0.95]), low serum bicarbonate (0.009, 0.85 [0.76-0.96]), and a hemodynamically significant patent ductus arteriosus for which ibuprofen was administered (0.003, 7.60 [2.03-28.47]) were identified as independent risk factors for sNEC.Conclusions: Our findings may support the clinician to identify infants with increased risk for sNEC, which may facilitate early decisive management and consequently could result in improved prognosis. What is Known: • In 27-52% of the infants with NEC, a surgical intervention is indicated during its disease course. • Absolute indication for surgical intervention is bowel perforation, whereas fixed bowel loop or clinical deterioration highly suggestive of bowel perforation or necrosi, is a relative indication. What is New: • Lower gestational age, early clinical onset, and no maternal corticosteroids administration are predictors for surgical NEC. • Low serum bicarbonate in the 3 days prior clinical onset and patent ductus arteriosus for which ibuprofen was administered predict surgical NEC.

Project description:BackgroundNeonatal necrotizing enterocolitis (NEC) is a common gastrointestinal emergency in newborns. Currently, the pathogenesis of the disease remains unknown. This study aims to determine the application value of serum markers in the selection of operation opportunities for NEC.MethodsThis study consisted of a retrospective analysis of the clinical data of 150 participants with NEC admitted to Maternal and Child Health Hospital of Hubei Province from March 2017 to March 2022. Participants were assigned to an operation group (n=58) and a nonoperation group (n=92) according to the presence or absence of surgical treatment. Serum sample data for serum C-reactive protein (CRP) and interleukin 6 (IL-6), serum amyloid A (SAA), procalcitonin (PCT), and intestinal fatty acid-binding protein (I-FABP) concentrations were estimated. To compare the differences in overall data and serum markers between the 2 groups, independent factors related to surgical treatment in pediatric patients with NEC were analyzed using logistic regression. The utility of serum markers in selecting surgical options in pediatric patients with NEC was analyzed by constructing a receiver operating characteristic (ROC) curve.ResultsCRP, I-FABP, IL-6, PCT, and SAA levels were higher in the operation group than in the nonoperation group (P<0.05). Multivariate logistic regression analysis confirmed that CRP, I-FABP, IL-6, PCT, and SAA were independent related factors of NEC surgical remedy (P<0.05). Meanwhile, ROC curve analysis yielded a serum CRP, PCT, IL-6, I-FABP, and SAA area under curve (AUC) of NEC operation timing of 0.805, 0.844, 0.635, 0.872, and 0.864, respectively; a sensitivity of 75.90%, 86.20%, 60.30%, 82.80%, and 84.50%, respectively; and a specificity of 80.40%, 79.30%, 68.35%, 80.40%, and 80.55%, respectively.ConclusionsThe serum markers CRP, PCT, IL-6, I-FABP, and SAA have certain guiding values in the choice of operation opportunity for pediatric patients with NEC.
