title: Microcolon-intestinal hypoperistalsis without megacystis: uncommon form of neonatal intestinal pseudoobstruction.
abstract: Two cases of microcolon-intestinal hypoperistalsis without megacystis are reported. They had dilated proximal small bowel and narrowed distal small bowel and malrotated microcolon. No organic obstructive intestinal lesion was found and double-barrel ileostomy was performed. The biopsy specimens showed ganglion cells to be normal in number and appearance in the entire intestinal wall. The ileostomy did not function postoperatively and drugs stimulating bowel movement failed to induce peristalsis. We have suggested that microcolon-intestinal hypoperistalsis without megacystis may be the cause of functional intestinal obstruction in neonates and it is a variant of megacystis-microcolon-hypoperistalsis syndrome.
