Megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is a rare congenital defect of visceral smooth muscle, primarily affecting females who present at birth with functional obstruction of the intestine, microcolon, dilation of the bladder, and secondary hydronephrosis. Total parenteral nutrition, adequate intermittent catheterization of bladder, and surgical corrections for intestinal malrotation are frequent modes of treatment for this disease without which rapid death ensues. In some instances, multivisceral organ transplantation has been undertaken with some success. Despite these clinical interventions, MMIHS often leads to premature death due to complications of therapy (summary by Halim et al., 2017).
