METHOD FOR RECONSTRUCTION OF SEGMENTAL BILE DUCTS Russian patent published in 2025 - IPC A61B17/11 A61M27/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to bile duct reconstructive surgery. An anterior and posterior branch of a right lobar duct and a left lobar duct 3 mm long are separated in the liver parenchyma within the unchanged tissues. A Roux loop of the small intestine is brought to a hepatic hilum, and enterotomy holes are made in a projection of the separated ducts in the intestinal wall along an antimesenteric edge. A posterior semicircle of three anastomosis of the anterior, posterior branches of the right lobar duct, the left lobar duct with a small intestine is formed. A drain tube is inserted into each duct and fixed to the duct wall. Each of the drainage tubes is delivered through the enterotomy holes into the lumen of the small intestine so that the tubes installed in the anterior and posterior branches of the right lobar duct remain in the intestinal lumen, and the drainage tube of the left lobar duct came out through the non-extinguished free end of the small intestinal loop switched off according to Roux. Drain tubes are connected to each other, trihepaticojejunoanastomosis is formed along anterior semicircle of anastomosis. A free end of the Roux-off small intestine loop is brought out in the form of a hepaticostoma with a drainage tube through an additional incision on the anterior abdominal wall.

EFFECT: method enables preventing inflammatory and suppurative postoperative complications of the abdominal cavity, reducing a risk of anastomosis stricture, biliary hypertension and cholestatic hepatitis due to sealing of bile ducts and their separate drainage for the period of healing of biliodigestive anastomosis.
