Morgagni hernia

Dr Sonam Vadera and Dr Jeremy Jones et al.

Morgagni hernias (alternative plural: herniae) are one of the congenital diaphragmatic hernias (CDHs), and are characterized by herniation through the foramen of Morgagni. When compared to Bochdalek hernias, Morgagni hernias tend to be:

  • 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.

Giovanni Battista Morgagni (1682-1771) was an Italian pediatric surgeon 8
