摘      要：BACKGROUND Hepatobiliary stone disease involves an intrahepatic bile duct stone that occurs above the confluence of the right and left hepatic ***-step percutaneous transhepatic cholangioscopic lithotripsy(PTCSL)using the percutaneous transhepatic one-step biliary fistulation(PTOBF)technique enables the clearing of intrahepatic stones and the resolution of ***,hepatolithiasis with associated strictures still has high residual and recurrence rates after one-step *** can achieve synchronized acquisition with a flat-panel detector during C-arm *** technical approach and application value of DynaCT biliary soft tissue reconstruction technology for the diagnosis and treatment of hepatolithiasis with bile duct stenosis were evaluated in this *** To explore the value of DynaCT biliary soft tissue reconstruction technology for the diagnosis and treatment of hepatolithiasis with bile duct stenosis,and to assess the feasibility and effectiveness of the PTOBF technique guided by DynaCT biliary soft tissue reconstruction *** The clinical data of 140 patients with complex biliary stenosis disease combined with bile duct stenosis who received PTOBF and were admitted to the First Affiliated Hospital of Guangzhou Medical University from January 2020 to December 2024 were *** patients were divided into two groups:DynaCT-PTOBF group(70 patients)and conventional PTOBF group(70 patients).These groups were compared in terms of the preoperative bile duct stenosis,location of the liver segment where the stone was located,intraoperative operative time,immediate stone retrieval rate,successful stenosis dilatation rate,postoperative complication rate,postoperative reoperation rate,stone recurrence rate,and stenosis recurrence *** DynaCT biliary soft tissue reconstruction technology was successfully performed in 70 *** DynaCTPTOBF group had a higher detection rate of target bile ducts where bile duct stone
