[Rectal irrigation and bowel decontamination for the prevention of postoperative enterocolitis in Hirschsprung's disease].

Unlabelled: The object is to determine the utility of rectal irrigation (RI) and bowel decontamination for the prevention of postoperative enterocolitis in Hirschsprung's disease.

Material And Methods: Between 1978 and 2005, 37 patients underwent surgical treatment for Hirschsprung's disease. Group 1 (1978-1993): 19 patients, 17 with rectosigmoid or long segment disease, and 2 total colonic aganglionosis (TCA).

[Usefulness of anorectal manometry in the neonatal diagnosis of Hirschsprung disease].

During 1992 through 1998 anorectal manometry studies have been carried out on 32 newborn, with age between 48 hours and 28 days and weight range of 1,400 and 4,200 g at the test moment. The test has been prescribed due to a retard in meconial evacuation in the 32 patients, moreover, 13 out of them also presented an intestinal obstruction or subobstruction. The anorectal manometry is carried out with a probe especially designed by us for newborn and a Hellige polygraph.

[Colonic aganglionosis with ileal involvement. Ileocolic plasty].

During 1994 through 1999, we have treated five patients (3 boys, 2 girls) with total colonic aganglionosis (TCA) and ileal involvement. In three of them we performed a diverting ileostomy in the neonatal period and at the age of four and five months respectively in the remaining two patients, due to intestinal obstruction. In these two last patients a diagnosis of Hirschsprung's disease was made by anorectal manometry and rectal biopsies in the neonatal period.

Thrombus in right atrium in two infants successfully treated with tissue plasminogen activator.

The widespread use of central venous catheters in children has increased thrombotic complications that warrant thrombolytic therapy. We report the cases of two infants, aged four and two months, with a mobile thrombus in the right atrium treated with recombinant tissue-plasminogen-activator (rt-PA) infused by a central venous catheter. Clot dissolution was obtained in both patients in eight and 44 hours, respectively.
