Abstract
Diaphragmatic eventration (DE) is an abnormal condition where a portion or the entire hemidiaphragm elevates due to insufficient muscle or nerve function while maintaining its anatomical attachments. On the other hand, congenital diaphragmatic hernias occur due to the abnormal development of muscular entities of the diaphragm, resulting in the displacement of abdominal contents into the thorax. The difference between diaphragmatic hernia and eventration is important as there is no true defect in DE. Ruptured eventration of the diaphragm is a rare entity, with only three cases reported in adults in literature till date, all on the left side. We report the first case of ruptured eventration of the diaphragm on the right side, which was repaired by a combination of laparoscopy and thoracoscopy and with double-mesh placement.
