Inclusion criteria
Inclusion criteria: (1) Patients who have lesions in the esophagus or periesophageal region (e.g. lymph nodes, pancreas, liver) which can be observed with EUS. Specific examples are as follows: 1. Pancreatic cancers that require evaluation of invation to vessels. 2. Esophageal/gastric varices that need to select appropriate location for sclerosing therapy or require evaluation of therapeutic effect. 3. Acute pancreatitis that require evaluation of blood flow inside the pancreas 4. Pancreatic cystic neoplasms that require detailed evaluation of internal structures (real-time evaluation of nodule, septum and mucus excluding partial volume effect). 5. Early stage esophageal/gastric cancers that require three dimentional evaluation of external wall vessels prior to endoscopic resection. (2) Patients between 20 and 80 years old at the time of enrollment. (3) Preservation of main organ functions at the time of diagnosis. (4) Provision of written consent to participate in the study.
Exclusion criteria
