Non-operative management of a large Morgagni hernia—an alternative approach?

Abstract

Morgagni’s hernia (MH) is a congenital diaphragmatic hernia with a small percentage of cases diagnosed in adulthood. The average age of diagnosis is 57 years, with 61% being female and 10–28% being asymptomatic. It is common practice to complete surgical repair of MH regardless of symptomology or size of the defect despite a paucity of evidence. This paper highlights the potential for non-operative management as a reasonable treatment option in large asymptomatic MH. A female in her 40s was referred following an abnormal spirometry result as a part of a routine pre-employment check. She subsequently had imaging, which showed a large MH with abdominal contents within the thoracic cavity. Following discussion at a multidisciplinary team meeting, it was decided that the risk of perioperative morbidity likely exceeded the risk of strangulation while asymptomatic, and thus surveillance was recommended.
