A typical case of megacystis microcolon intestinal hypoperistalsis syndrome (MMIHS) is reported. The patient, an infant girl, was fed only by total intravenous nutrition and is now 3 years old. The distribution of several gut peptides was examined in the resected small intestine using an immunohistochemical method. Vasoactive intestinal polypeptide (VIP) and peptide histidine methionin (PHM)-containing nerve fibers were decreased; however, substance P- and leucine enkephalin (Leu-ENK)-containing fibers were increased. The imbalance between several kinds of gut peptides might be one of the causes of aperistalsis in MMIHS. This is the first report about the gut peptides of MMIHS.
