METHOD FOR LIVER WOUNDS CLOSURE Russian patent published in 2019 - IPC A61B17/04 

FIELD: medicine.

SUBSTANCE: invention refers to surgery, and can be used for closing liver wounds in hepatic injuries. Method involves performing liver wounds inspection, stopping bleeding from hepatic wound by electric coagulation, measuring wound depth, cutting a mesh prosthesis from an esphil standard polypropylene mesh, length of prosthesis is comparable to length of wound, width is sum of two sizes of wound depth and four centimetres. Mesh prosthesis is laid on the wound bottom so that the edges of the mesh prosthesis are located from the wound edge in the distal directions by 2 cm. Healing of liver wound together with mesh prosthesis with U-sutures atraumatic needle, non-absorbable suture of size 0. Suture is started from the upper angle of the wound at distance of 2 cm in the distal direction from the wound edge, thread advance from top to bottom through polypropylene mesh, through capsule and hep parenchyma to entire depth of liver with needle prick-out in bed of liver wound through polypropylene mesh. Needle is then drawn from the bottom of the liver wound through the polypropylene mesh, through the parenchyma, the liver capsule, through the polypropylene mesh, needle prick-out at the upper angle of the wound at distance of 2 cm in the distal direction from the wound edge on the opposite side. Further, from the exit point of 1.5 centimetre thread in the caudal direction, the U-suture is continued in the reverse order with the thread exit from the opposite side of the wound. U-shaped sutures are applied by the above method along the entire length of the wound. Interval of sutures 1.5 centimetres. Wound edges are brought together by tightening U-shaped sutures until haemorrhage stops. Abdominal cavity is drained. Laparotomic wound is closed in layers.

EFFECT: method enables preventing suture cutting, reliably matching liver tissue, providing reliable haemostasis with minimizing bleeding risk in the early postoperative period, minimizing the risk of developing intrahepatic abscesses in the late postoperative period, that is higher clinical effectiveness.
