METHOD FOR SUTURING THE LIVER Russian patent published in 2021 - IPC A61B17/06 

FIELD: medicine; abdominal surgery.

SUBSTANCE: invention relates to medicine, namely to abdominal surgery, it can be used in performing surgical operations on the liver. The first suture is applied to the lower edge of the wound surface using a bilateral surgical atraumatic needle, threading one of the working ends of the needle. The needle is passed through the parenchyma thickness from the visceral surface of the organ to the diaphragmatic one, retreating from the edge of the liver wound surface by 10 mm. After that, the thread is removed from the working end of the needle and tied, and the needle remains in the thickness of the organ parenchyma. Then, each working end of the needle is threaded. The needle is passed through by reverse traction for the second working end in the liver parenchyma thickness until the first working end reaches the ½ of the plane of the wound surface of the liver stump. After that, the needle is tilted towards the non-sutured part of the organ and the first threaded working end of the needle is output at the formed angle of inclination on the diaphragmatic surface of the liver, retreating from the edge of the wound by 10 mm. The thread is removed, tied, and the needle is threaded again. In this case, the second working end with the thread is located at least on the ½ of the plane of the wound surface of the liver stump, but is not completely removed from the liver. Then, the second working end of the needle is tilted in the direction of the non-sutured liver parenchyma, and the needle is passed through the visceral surface of the organ perpendicular to it, retreating from the edge of the wound by 10 mm, so that the first working end is on the ½ of the plane of the wound surface of the liver stump. From the second working end of the needle, the thread is removed, tied, and the needle is threaded again. The first working end of the needle is tilted towards the non-sutured part of the organ and the needle is passed by the first working end over the diaphragmatic surface of the liver at the formed angle, retreating from the edge of the wound by 10 mm. The thread is removed, tied, and the needle is threaded again. Sutures are applied until the posterior edge of the liver wound surface is reached. The last suture is applied by inserting a thread into one of the working ends of the needle and stitching it over the entire thickness of the remaining parenchyma of the liver wound surface. The thread is tied.

EFFECT: method ensures the achievement of hemostasis and cholestasis, shortening the operation time, facilitating the work of the surgeon, preventing postoperative complications by suturing in both directions, relatively to the ½ of the plane of the wound surface of the liver stump, without capturing the parenchyma of adjacent sutures.
