Epidemiology
Microgastria is an extremely rare anomaly, approximately less than 100 cases have been reported (c. 2019) 1,2. Isolated microgastria is suspected to occur in only 4% of patients, with most patients having other concomitant congenital abnormalities (e.g. microgastria-limb reduction complex) 2.
Clinical presentation
Most patients have postprandial vomiting, recurrent aspiration pneumonia, and growth impairment due to poor nutrition.
Treatment and prognosis
There is no established definitive management, with case reports suggesting the use of Hunt-Lawrence jejunal pouch for gastric augmentation, however, the evidence is sparse 2.
