Congenital Diaphragmatic Eventration in the Neonatal Period: Systematic Review of the Literature and Report of a Rare Case Presenting with Gastrointestinal Disorders

BACKGROUNDThe term congenital diaphragmatic eventration (CDE) refers to an anatomical abnormality of the diaphragm. It is a very rare condition; however, early and prompt diagnosis is of very great importance due to possible life-threatening complications. Most severely affected patients are neonates, usually presented with respiratory distress symptoms. The aim of this study was to systematically review the existing literature and to consolidate data on CDE in neonates as well as to report a case of a neonate with congenital diaphragmatic eventration of the left hemidiaphragm and clinical signs and symptoms of the gastrointestinal tract. METHODSAn electronic search of the PubMed and Scopus databases was performed regarding studies evaluating the clinical presentation, diagnosis methods, treatments, and outcomes of CDE in the neonatal population. RESULTSData from 93 studies were integrated into our review, reporting 204 CDE cases, and according to them, the male/female ratio was 1/1 with a predominance of right-sided eventration. The diagnosis was primarily established by chest X-ray; surgical intervention was the most frequent treatment. The recurrence rate was 8.3% (9/109 cases). CONCLUSIONSEarly and accurate diagnosis of CDE and repair of the diaphragm can prevent complications, reduce morbidity, and improve the quality of patient's life.
