“…By this term we can mean the doubling of the gallbladder, the septum of the bladder, the bladder deeply immersed in the parenchyma of the liver, the gallbladder with mesentery and the left-sided position of the gallbladder. It should be noted that most of these anatomical features (except for the deep position of the bladder) do not present complications for the surgeon during cholecystectomy [7][8][9][10][11][12].…”

During any surgery, in addition to pathology-related factors, it is necessary to evaluate the individual features of the anatomy of a particular area or complex of organs. The relevance of such data is confirmed by the results of numerous studies that show that half of patients are characterized by certain anatomical variants, including the location of the arteries and biliary tract. The purpose of the work is to establish the peculiarities of the morphometric parameters of the components of the hepatic-duodenal ligament. The study was based on 50 preparations of fetus corpses (4 to 10 months) and 10 newborns without external signs of anatomical abnormalities or congenital malformations. Adequate anatomical methods were used during the study: macropreparation, injection of blood vessels, making topographic anatomical sections, morphometry. Statistical analysis of the obtained data was performed using the licensed program RStudio. During the perinatal period, the length of the hepatic-duodenal ligament was found to increase from 5.224±0.572 mm in fetuses for 4 months to 32.12±1.77 mm in newborns. The chart of change of the average values of its length by months of prenatal development indicates uneven increase of organometric parameters. From 4 to 5 months observed a significant increase in the length of the hepatic-duodenal ligament, while from 5 to 7 months of development observed a period of relative slowdown of its length, and from 5 to 6 months of development even a relative decrease in length. The period from 7 to 10 months determines the period of accelerated growth of ligament. The indices of the width of the hepatic-duodenal ligament in the perinatal period increased from 3.292±0.227 mm in fetus of 4 months to 21.25±0.938 mm in newborns. The width increases are not uniform. The periods of accelerated development (4-5 months and 9 months – newborns) and the period of slow development (5-8 months) were observed. It was proved that there are periods of accelerated and slow development, in which during periods of intensive development, organometric indicators always differed significantly, were smaller than the previous ones and outweighed the following ones respectively (4-5 months and 7-9 months, р˂0.05). Regarding the periods of slow development, the organometric indicators in these periods did not differ significantly (р˃0.05). Therefore, analyzing the dynamics of changes in the morphometric parameters of the components of the hepatic-duodenal ligament, revealed periods of their accelerated and slow growth.
