Abstract
A 78-year-old woman was referred to our hospital with a right anterior pericardiophrenicabnormal mass which was enlarging gradually. Chest CT, MRI and celiac angiography gavea diagnosis of Morgagni hernia whose content was probably omentum. Video-assisted thoracicsurgery was conducted, but narrow diaphragmatic defect made it difficult to replace theomentum, so that mini-thoracotomy was additionally performed. After replacement of thehernia content and resection of the hernia sac with an endocutter, the diaphragamatic defectwas closed and reinforced with several interrupted sutures. Since video-assisted thoracicsurgery is a less invasive technique, it is useful in the treatment of diaphragamatic hernia.However, as far as Morgagni hernia is concerned, mini-thoracotomy seems necessary becauseof the difficulties in replacing hernia content and repairing the diaphragamatic defect.
