The clinico-statistical investigation performed has revealed that the compressive suture of the transverse termino-lateral gastrojejunal anastomosis in gastric Billroth-II resection formed with the help of a titanium nickelide device considerably lowers traumatism of the operation and bacterial contamination of the operation area, abdominal cavity and the abdominal wall wound which leads to pronounced (3-4 times) drop of the level of early postoperative complications and minimizes the postoperative lethality.
