title: [Anatomohistological characteristics of Meckel's diverticulum in human fetuses].
abstract: OBJECTIVE
  Meckel's diverticulum (MD) is the most frequent anomaly of the small intestine. It appears after incomplete obliteration of the omphalomesenteric or viteline duct which normaly obliterates and disappears by the 9th week of gestation. The majority of MD do not give rise to any clinical symptoms and are encounted either incidentally, at examination or intervention, or due to complications which may occur (obstruction, hemorrhagy, rupture), and are described in many clinical reports. The aim of the study was to find out the incidence of MD in fetuses when the development of the alimentary tract is already finished.
  
  
  METHODS
  The investigation was performed on 150 human fetuses of different sex and gastational age, using microdissection method. The cases with MD were photographed, described, their positions and dimensions were registered. The samples of MD taken for histological investigation were dyed with hematoksilin eosin method.
  
  
  RESULTS
  Meckel's diverticulum was found in five fatuses (three male and two female); in one case the fibrous band was found. All of them were located on animesenteric margine of the small intestine at the average distance of 92.5 mm from the ileocecal junction. They were of different shape and dimensions, but of the normal constitution of the small intestine.
  
  
  CONCLUSIONS
  The incidence of MD was 3.3%, and 4% of all the anomalies of the intestines connected to the disappearance of the viteline duct. It was more frequent in the male, located on antimesenteric margine of the small intestine, at the destination which highly correlated to the age of the fetus. Meckel's diverticule were of different shapes and dimensions but of the typical constitution of the small intestine.
