HUMAN STOMACH SYNTOPIA AT 16-22 WEEKS OF GESTATION

Abstract

Objective. Obtaining new information on the syntopy of parts of the stomach at 16-22 weeks of the intermediate fetal period of human ontogenesis.

Material and methods. 40 fetuses of both sexes aged from 16 to 22 weeks of ontogenesis were studied. Four age groups were formed in the work (16-17, 18-19, 20-21 and 22 weeks), of 2 weeks layout. The method of macromicroscopic preparation, bone cut- ting according to the method of N.I. Pirogov, methods of morphometry, histotopographic, statistical analysis, and photographic method were used.

Results. The article presents the results of studying the syntopia of the cardia, fundus, body and pyloric part of the human fetus stomach with adjacent abdominal organs, as well as the dynamics of changes in the age range from 16 to 22 weeks of prenatal development.

Conclusions. 1. Syntopy features of various parts of the human stomach at 16-22 weeks include a weakly expressed contact with the diaphragm, the anterior wall in the area of the stomach body that is almost completely covered by the lobes of the liver, a small curvature contact with the caudate lobe of the liver for a longer distance, no contact with the left kidney. 2. Throughout the study period, there is a tight coupling of the posterior wall of the stomach with the left adrenal gland. 3. Hepatic-duodenal, hepatic-gastric, gastro-diaphragmatic, and gastro-splenic ligaments are well defined. 4. The pregastric and omentum sacs at 16-22 weeks of ontogenesis are slit-like gaps. 5. Horizontal and sagittal cuts make it possible to determine the characteristic features of gastric syntopia.

The data obtained expand and add new information to the facts already available on the age-related anatomy and topography of the stomach in newborns, children, and adults. The obtained new data on gastric syntopia are of professional interest to morphologists and clinicians.
