[Surgical anatomy of the anterior abdominal wall in normal viscera, dolichoviscerosis and visceroptosis].

There are three types in position of the abdominal internal organs: visceronorm, dolichoviscerosis and visceroptosis. The anterior abdominal wall also has its own anatomical peculiarities at every type of the internal organs position. Anatomical differences of its structure at visceronorm and dolichoviscerosis in comparison with visceroptosis are characterized as following: the area of aponeurotic formations of the anterior abdominal wall at dolichoviscerosis and visceroptosis increases and that of the muscular-decreases. Umbilical and inguinal rings are essentially dilated in comparison with those at visceronorm. It means that at dolichoviscerosis and visceroptosis there are anatomical prerequisites for development of external hernias in the anterior abdominal wall. A considerable mobility of the intestinal tract loops at dolichoviscerosis and visceroptosis results in certain disturbances of its function and their outlet into hernial sacs.
