PURPOSE: We evaluated the diagnostic and therapeutic capabilities of endoscopic ultrasonography (EUS) in pancreaticobiliary diseases. We aimed to validate the efficiency of detective flow imaging (DFI), shear wave elastography (SWE), and other advanced imaging techniques.
METHODS: We used new EUS scopes (EG-740 UT and G-580UR) and the latest ultrasound equipment (ARIETTA 850) (Fujifilm Healthcare, Kanagawa, Japan). Diagnostic procedures were performed in 16 cases, including pancreatic cancer and intraductal papillary mucinous neoplasms, and therapeutic procedures in eight cases, involving complex biliary and pancreatic interventions. The utility of SWE in assessing tissue stiffness was quantified by measuring the shear wave velocity (SWV) in pancreatic cancer and autoimmune pancreatitis.
RESULTS: We found no significant difference in SWVs among different pancreatic conditions; however, significant variations were observed in the net percentage of effective SWV. Interventional EUS had a 100% technical and clinical success rate, demonstrating the efficacy of new imaging techniques and equipment in enhancing procedural safety and diagnostic accuracy.
CONCLUSIONS: The integration of advanced EUS imaging technologies, particularly DFI, contrast-enhanced EUS, and SWE, significantly enhances the diagnosis and treatment of pancreaticobiliary diseases.
