Résumé

Introduction: Necrotizing Enterocolitis (NEC) remained a dramatic complication leading to death or neonatal morbidities in preterms. For some, Intra-Abdominal Hypertension (IAH) and Abdominal Compartment Syndrome worsened the multi-organ failure. An open abdomen surgery could be an alternative to conventional surgical treatment to move beyond this stage. Objectives: To retrospectively describe the clinical course, pre- and post-operative features of preterms suffering from severe NEC with IAH treated by open abdomen surgery and referred to our center from October 2007 to September 2019. Our secondary objective is to identify various risk factors for mortality in this population. Methods: Data on neonatal, clinical, biological, pre and post-operative features and outcome were collected. Univariate analyses were performed to compare their pre and post-operative features stratifying on outcome. Results: Among 29 included patients, 14 (48%) survived to discharge without short bowel syndrome. Death was associated with an earlier postnatal age at NEC (16.3 ± 9.1 versus 31.3 ± 25.9 days; p = 0.004) and followed a withdrawal of treatment in 60% of cases. Surgery was associated with a significant improvement of respiratory and hemodynamic features (decrease of mean ventilator pressure from 13.1 ± 5.4 to 11.3 ± 4.0 cmH2O, p < 0.001), oxygen requirement (mean FiO2 decreased from 65.0% ± 31.2 to 49.0% ± 24.6, p < 0.001) and inotropic score (from 38.6 ± 70.1 to 29.9 ± 64.3, p < 0.001). In the survival group, pre and post-operative findings exhibited a significant increase of serum lactate concentrations from 2.7 ± 1.6 to 11.0 ± 20.3 mmol/L (p = 0.02) but a similar pH. Conclusion: Open abdomen surgery could be considered to rescue preterms with near fatal NEC. IAH and Abdominal Compartment Syndrome in these preterms should be investigated through further studies.
