METHOD FOR IMPLANTATION AND FIXATION OF A POLYPROPYLENE SLEEVE-IMPLANT DURING THE FORMATION OF A GASTROSTOMY Russian patent published in 2023 - IPC A61B17/00 A61F2/00 

FIELD: medicine; surgery; gastroenterology.

SUBSTANCE: stomach is brought out into the laparotomy wound. A stem gastrostomy is formed. In the left hypochondrium in the projection of the rectus abdominis muscle, a wound channel is formed, through which the gastrostomy is brought out to the skin of the anterior abdominal wall. The diameter of the gastrostomy is measured in the zone of its adjoining to the aponeurosis of the anterior abdominal wall and the thickness of the subcutaneous fat. A sleeve-implant is formed from a polypropylene mesh, for which a trapezoidal blank of the sleeve-implant is cut out and folded in the form of a truncated cone, while the height of the formed sleeve-implant is not more than half the thickness of the subcutaneous fat layer. The sleeve-implant is placed from the side of the skin on the gastrostomy with partial placement of the tissue of the sleeve-implant on the tissue of the anterior abdominal wall aponeurosis and is fixed to the aponeurosis of the anterior abdominal wall with involvement of the gastrostomy serous-muscular tissues in the nodal suture. The gastrostomy is additionally fixed to the skin of the wound channel.

EFFECT: method reduces the risk of gastrostomy failure and the formation of adhesive process of the abdominal organs in the postoperative period due to the placement of the sleeve-implant on the outer side of the anterior abdominal wall, which excludes contact of the material of the sleeve-implant with internal organs, reduces the risk of postoperative complications in the postoperative period.
