Inclusion criteria
Inclusion criteria: 1.Adult patients aged 20 years or older at the time of obtaining informed consent. 2.Patients with suspected solid lesions in the pancreaticobiliary region or adjacent organs detectable by endoscopic ultrasonography (EUS), including the hepatic hilum, duodenum, and lymph nodes, for whom EUS-guided tissue acquisition (EUS-TA) was planned to establish a definitive diagnosis. This includes cases in which EUS observation was performed regardless of whether EUS-TA was ultimately carried out. 3.Patients in whom EUS observation with concomitant use of EUS-AI can be performed as part of routine clinical practice. 4.Patients who have received a sufficient explanation of the purpose and content of this study and have provided written informed consent of their own free will.
Exclusion criteria
Exclusion criteria: 1.Patients in whom EUS examination is deemed difficult due to poor general condition and inability to undergo sedation. 2.Patients who have previously undergone EUS-AI for the same target lesion and are scheduled to undergo EUS-guided tissue acquisition (EUS-TA) for purposes such as tumor panel testing. 3.Patients who are judged by the principal investigator or sub-investigators to be inappropriate for inclusion in this study.
