The review examines the age characteristics of the greater omentum, its metric and topographic parameters. It has been revealed that the shape of the greater omentum can be single-, two- and multi-lobular, which is determined by its loose part. The linear dimensions of the greater omentum are consistent with the stature type and age range. The length of the loose portion of the greater omentum varies widely and ranges from 20 to 43 cm (average 31.58 ± 0.8 cm); the area of the surface of the greater omentum in adults reaches an average of 0.81 m2, which is almost half the entire surface of the peritoneum and is on average 0.40 m2. The range of individual variability in the size of the greater omentum varies at different ages of the child's development. It is especially large at the end of the first year of life. In the next 2-4 years of life, the range of variability of the greater omentum narrows slightly, the largest growth of linear sizes of the greater omentum is observed during the first year of life of the child and they increase by 2 times, and the area – by 3 times. The asymmetry of the longitudinal dimensions of the greater omentum on the right and left also increases. The boundaries of the greater omentum are: liver, spleen, parietal peritoneum of anterior abdominal wall, small intestine, ascending and descending part of the colon. It has been revealed that the main source of blood supply of the human greater omentum is the abdominal and upper mesenteric arteries, the anterior duplication of the greater omentum receives nutrition from the short and long omental arteries, and numerous small arterial vessels are involved in the blood supply of the upper left part of the omentum; they are located in the thickness of the gastro-splenic ligament. Usually 5-13 branches ramify from the right gastrointestinal artery, and one branches off from the left one. The left gastrointestinal artery has a length of 7 to 21 cm and the right gastrointestinal artery – from 10 to 38 cm.
