Surgical treatment of gastric cancer using radical operations in the form of total gastrectomy (TG) and subtotal gastric resection is accompanied by a significant number of postoperative pathological syndromes (42%). Improving the functional results of TG in the long-term postoperative period remains a pressing problem today. Aim. To determine the role of 3D reconstruction and modeling of jejunogastroplasty (artificial ventricle) (JGP) after TG to improve functional outcomes of surgical treatment of bleeding gastric cancer. Materials and methods. The results of 246 TG for 3 periods were analyzed: I (1983-1999) - 147 patients; II (2000 - 2010) - 71; III (2011-2024) - 28. Acute bleeding gastric cancer was in 170 patients. Surgical intervention for acute bleeding gastric cancer was performed mainly in the delayed period after stopping the bleeding
