Diaphragmatic eventration is a rare congenital developmental defect of the muscular portion of the diaphragm, which appears attenuated and membranous, maintaining its normal attachments and its anatomical continuity. It has been attributed to abnormal myoblast migration to the septum transversum and the pleuroperitoneal membrane. Eventration can be unilateral or bilateral, partial or complete. It is more common in males, and involves more often the left hemidiaphragm. Eventration results in diaphragmatic elevation (cephalad displacement). Most adults are asymptomatic and the diagnosis is incidentally made by chest radiography. The commonest symptom in the adults is dyspnoea, while orthopnoea, mild hypoxemia, tachypnoea, respiratory alkalosis, palpitations, and non specific gastrointestinal symptoms may be present. Surgery is indicated only in the presence of symptoms. The established surgical treatment is diaphragmatic plication. Various techniques and approaches have been employed. We present a simple surgical technique of a 3-port video assisted thoracoscopic plication of the left hemidiaphragm in the adult.
