Brief summary

The relevance of the problem of timely and accurate diagnosis of the etiology of acute cholangitis is beyond doubt. With the development of medical imaging technologies, increasing demands are placed on the accuracy of identifying the level and extent of the biliary block. In addition to the staging of malignant diseases and the choice of decompression methods for cholangitis, one cannot overestimate the possibilities of preoperative planning available with the use of some methods of radiation diagnostics. The paper presents data on the assessment of the diagnostic potential of transdrainage CT cholangiography in acute cholangitis. Objective. To determine the significance of transdrainage CT cholangiography in the complex diagnosis of the cause of biliary block in patients with acute cholangitis. Materials and methods. The study included 68 patients with acute cholangitis who were treated at the St. I.I. Janelidze from September 2016 to January 2022. Results. It has been established that transdrainage CT cholangiography in the diagnosis of both benign and malignant biliary block in the etiology of acute cholangitis is more informative than MR cholangiography and ERCP. Findings. Transdrainage CT cholangiography is a promising accurate technique for determining the cause of acute cholangitis in patients with external biliary drainage. Also, the technology under consideration can be used for detailed preoperative planning for radical interventions of the second stage.
