Congenital diaphragmatic hernia: study of morbidity and mortality during the period 2012-2022

Abstract

Congenital diaphragmatic hernia is an anatomic defect that allows passage of abdominal structures through the thoracic cavity, generating cardiac and pulmonary growth detention; this disorder has an incidence of 2.3 for every 10.000 live births, predominantly in female sex, in recent years Venezuelan mortality index was around 70%; characterized by acute breathing difficulty, it may be associated or not to structure or cromosomic anomalities: diagnosis is made prenatally by ultrasound, treatment consists of surgical resolution of defect. In this study we search to determine morbimortality of pediatric patients with congenital diaphragmatic hernia after surgical resolution intervention between 2012-2022 in Centro Médico Docente La Trinidad through a descriptive retrospective observational study, patients included had prenatal diagnosis, follow-up an treatment in our center; a form was made to recollect data from clinical histories. As a result 10 patient with diaphragmatic hernias in the last 10 years was determined, mortality index was 60%, most presented pulmonary hypertension, treated effectively with vasodilators; defect correction in 50% of patients was by minimally invasive techniques, thanks to this a shorter hospital stay was observed. In conclusion, this study provides low documented numbers from our health system, allowing improvement of therapy in this disorder for a longer survival.
