          Abstract

          Megacystis Microcolon Intestinal Hypoperistalsis Syndrom (MMIHS) is a quite rare congenital and fatal disease which was firstly defined by Berdon and his colleagues. It appears through a widely enlarged bladder and microcolon and its cause is unknown (Berdon et al., 1976; Carmelo et al., 2005; Makhija et al., 1999; Loening-Baucke and Kimura 1999; Redman et al., 1984; Hsu et al., 2003; Yigit et al., 1996; Srikanth et al., 1993). The disease is found in females three or four times more than in males (Srikanth et al., 1993; Sen et al., 1993; Hirato et al., 2003). Most of the cases die within the early months of their lives (Yigit et al., 1996; Srikanth et al., 1993; Sen et al., 1993; Hirato et al., 2003). We present the case of a female newborn with antenatal ultrasound revealing intestinal mass and bilateral hydroureteronephrosis. The case was admitted for intestinal obstruction after birth.

          Failure to pass meconium: diagnosing neonatal intestinal obstruction.

          Timely passage of the first stool is a hallmark of the well-being of the newborn infant. Failure of a full-term newborn to pass meconium in the first 24 hours may signal intestinal obstruction. Lower intestinal obstruction may be associated with disorders such as Hirschsprung's disease, anorectal malformations, meconium plug syndrome, small left colon syndrome, hypoganglionosis, neuronal intestinal dysplasia and megacystis-microcolon-intestinal hypoperistalsis syndrome. Radiologic studies are usually required to make the diagnosis. In addition, specific tests such as pelvic magnetic resonance imaging, anorectal manometry and rectal biopsy are helpful in the evaluation of newborns with failure to pass meconium.

            Megacystis-microcolon-intestinal hypoperistalsis syndrome: a visceral myopathy.

            Two newborn infants with megacystis-microcolon-intestinal hypoperistalsis syndrome are described. Review of the literature revealed twenty previously reported cases of this syndrome. Electron microscopic examination of the ileum and urinary bladder showed vacuolar degenerative changes in the smooth muscle cells with abundant amount of connective tissue between the muscle cells. These ultrastructural findings suggest that a degenerative disease of smooth muscle may be the cause of megacystis microcolon intestinal hypoperistalsis syndrome.

              Intestinal and multivisceral transplantation in children with severe gastrointestinal dysmotility.

              Severe gastrointestinal dysmotility (GID) impairs patients' quality of life and is almost uniformly fatal after complications of parenteral nutrition. Intestinal and multivisceral transplants have been used as alternative treatment of these disorders. We studied patients with GID treated with transplantation in our center, and reviewed their outcome to determine the therapeutic efficacy of multivisceral transplants. The transplant database was searched for patients with GID from 1994 to 2001. We excluded patients with Hirschsprung disease, scleroderma, and diabetic enteropathy. We reviewed explanted organs, histochemistry, and immunohistochemistry and classified cases by etiology. We selected 12 children with GID from 124 patients transplanted. Nine presented before 1 year and 3 started with symptoms between 2 and 8 years. By combined clinical and histopathological features, 6 were classified as megacystis microcolon intestinal hypoperistalsis syndrome, 4 as chronic idiopathic intestinal pseudoobstruction, and 2 as intestinal neuronal dysplasias. Six patients died during the follow-up from 21 to 546 days after transplant. The Kaplan-Meier actuarial survival rates were 66.7% at 1 year and 50% at 3 years. Multivisceral transplantation is a valuable therapeutic alternative for children with severe GID who cannot be adequately managed with parenteral nutrition.
