Morgagni hernia

Morgagni hernias are one of the congenital diaphragmatic hernias (CDH), and is characterized by herniation through the foramen of Morgagni. When compared to Bochdalek hernias, Morgagni hernias are:

  • anterior
  • more often right-sided (~90%)
  • small
  • rare (~2% of CDH)
  • at low risk of prolapse

Only ~30% of patients are symptomatic. Newborns may present with respiratory distress at birth similar to a Bochdalek hernia. Additionally, recurrent chest infections and gastrointestinal symptoms have been reported in those with previously undiagnosed Morgagni hernia.

Morgagni hernias most often contain omental fat, but transverse colon (60%) or stomach (12%) may be included within the hernia. 

Some sources recommend laparoscopic surgical repair, even in asymptomatic patients, to avoid the risk of strangulation of the hernia contents 6.
