The greater omentum (omentum gastrocolica) is a filmy apron draped over the transverse colon and coils of the small intestine. Clinical importance of the omentum have increased in recent years as it is a unique structure being highly vascular. Intact omentum has been used for a variety of clinical reasons which included attempts to increase blood flow to the ischemic heart, brain and legs; to prevent or repair vesicovaginal fistulas; to protect at operation previously irradiated pelvic organs at operation; to treat lymphedema and hydrocephalus; to repair radionecrosis of the chest wall or flexion creases for reconstruction of the breast and to protect a previously irradiated carotid artery after radical neck dissection. The arterial structure of omentum influences the manner in which the omentum can be a lengthened. Also, it is important to know the omental limits before laparotomy. The main aim of this research was to determine the range of lenght and width of omentum and then to correlate them with the height of the the person present. Thus one is able to predict the size and limits of omentum laparotomy. In this study, involving a series of 107 cases, the size of omentum was determined and the types of vascularity were assessed. Correlations between height and omental width, patients' height and omental length were calculated
