AB ESSENTIALS  OF  DIAGNOSISEndoscopic  ultrasound  (EUS)  is  a  critical  tool  in  cancer  staging  and  is  superior  to  computed  tomography  (CT)  and  positron  emission  tomography  (PET),  in  locoregional  esophageal  cancer  staging.EUS-guided  fine-needle  aspiration  (EUS-FNA)  is  the  most  sensitive  method  for  diagnosing  pancreatic  cancer;  overall  accuracy  of  EUS  is  similar  to  CT  for  assessing  vascular  invasion.EUS  helps  evaluate  subepithelial  lesions,  although  the  yield  of  EUS-FNA  is  lower  for  subepithelial  than  for  extraluminal  lesions.EUS  is  as  an  important  tool  in  diagnosing  chronic  pancreatitis.Diagnostic  yield  for  EUS  is  similar  to  magnetic  resonance  cholangiopancreatography  (MRCP)  in  detecting  choledocholithiasis  with  the  choice  of  modality  guided  by  local  availability.
