Megacystis Microcolon Intestinal Hypoperistalsis Syndrome: MMIHS

Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a rare congenital condition, and such patients tend to present with abdominal distension, a largely dilated nonobstructive bladder, microcolon, and severe functional intestinal obstruction without structural atresia or stenosis in the neonatal period. Currently, the etiology is not well understood, and there is no specific treatment for this condition. The majority of MMIHS patients repeat the intestinal obstruction and enteritis, so they require long-term PN and drainage stomas. The prognosis remains poor.
