Diagnostic yield of endoscopic ultrasound-guided tissue acquisition of solid pancreatic lesions after inconclusive percutaneous ultrasound-guided tissue acquisition

Introduction After a failed percutaneous ultrasound (US)-guided sampling, it is recommended that endoscopic ultrasound (EUS)-guided tissue acquisition (TA) be performed for non-resectable solid pancreatic lesions according to the European Federation of Societies for Ultrasound in Medicine and Biology. However, the diagnostic performance of EUS-guided TA in this setting is unknown.Methods We retrospectively analyzed the performance and safety of...
