The postenteritic syndrome or persistent postenteritic diarrhoea is a disease with chronic evolution (over 2-3 weeks), occurring immediately after an acute gastroenteritis, requiring, in most cases, hospitalization. The exact pathogenesis of postenteritic persistent diarrhea is not precisely known, several factors being probably involved. The main etiopatogenic links intervening in the manifestation of the postenteritic syndrome in children are the intestinal pathogenic germs, the occurrence and persistency of intestinal mucous lesions and the functional insufficiency of the small intestine, besides other favourizing factors that may be involved. The study was carried out on a group of 149 children, with ages between 1-29 months, hospitalized, between Oct. 2005-Dec. 2009, in the Section of Gastroenterology at St. Maria Clinical Hospital for Children of Iasi.
