Revolutionizing hepatolithiasis management: Transformative role of DynaCT in imaging and intervention

In this editorial, we comment on the article by Ye et al. We specifically focused on the novel use of DynaCT biliary soft tissue reconstruction technology in the diagnosis and treatment of hepatolithiasis with bile duct stenosis, which is an innovative approach for enhancing the preoperative evaluation and surgical outcomes in hepatolithiasis. This study also highlights the limitations of conventional imaging techniques such as computed tomography and magnetic resonance cholangiopancreatography, which have low sensitivity for small stones and complex biliary strictures. Given the intricate anatomy of the biliary system and the challenges posed by limited visualization using conventional methods, DynaCT addresses these issues by providing high-resolution, three-dimensional reconstruction of the bile ducts, stones, and vascular structures, thus improving anatomical clarity and enabling precise surgical planning. We also focused specifically on the limitations of DynaCT, such as the need for specialized equipment and patient selection criteria, as well as its advantages and disadvantages compared with conventional PTOBF approaches. Overall, DynaCT represents a significant advancement in hepatolithiasis management, with the potential to become a standard imaging modality for safer and more effective biliary procedures.
