METHOD FOR FORMING EXTERNAL PANCREATIC HEPATICOSTOMA USING EXTERNAL OR EXTERNAL-INTERNAL CHOLANGIOSTOMA Russian patent published in 2025 - IPC A61M25/01 A61B17/11 A61M27/00 

FIELD: medicine.

SUBSTANCE: invention refers to medicine, namely to abdominal surgery, gastroenterology. At the first stage, the patient undergoes external or external-internal percutaneous-transhepatic cholangiostomy (PTCS). At the second stage, the obstructive jaundice is relieved by removing the pancreaticoduodenal complex. When forming a posterior semicircle of the terminolateral pancreatojejunoanastomosis, a drainage catheter is inserted into the main pancreatic duct, fixed to the pancreas and brought out through the formed hole in the jejunum for hepaticojejunoanastomosis. Drainage of the main pancreatic duct is connected to the drainage of the PTCS, and the cholangiostomy drainage is tractioned by extending the drainage catheter of the main pancreatic duct of the pancreatic stump outside through the cholangiostoma opening in the intercostal space and fixed to the skin. Anterior semicircle of the pancreatojejunoanastomosis and hepaticojejunoanastomosis is formed on the drainage of the main pancreatic duct.

EFFECT: method allows to improve the course of the postoperative period, increase the effectiveness of the surgical treatment, reduce the incidence of surgical complications; in case of development of pancreatojejunoanastomosis failure, pancreatic hepaticostoma is controllable, which significantly reduces the risk of developing life-threatening complications, such as postoperative peritonitis and arrosive haemorrhage, by forming an external pancreatic hepaticostoma using an external or external-internal cholangiostoma.
