BACKGROUND: US-guided hepatico -gastrostomy, choledocho-duodenostomy and choledocho-antrostomy are advanced procedures on biliary and pancreatic endoscopy and together make up the echo-guided biliary drainage. Hepatico - gastrostomy is indicated in cases of hiliar obstruction, while the procedure of choice is choledocho - duodenostomy in distal lesions. Both procedures must be done only after unsuccessful ERCP. AIMS: To clarify to the readers about indication of these procedures, they must be made under a multidisciplinary view while sharing information with the patient or legal guardian. METHODS: All series cases report and selected cohort studies were selected according to the DDTS system in which key words were EUS biliary drainage, choledocho-duodenostomy, hepatico-gastrostomy, EUS, palliation and pancreatic biliary advanced cancer. RESULTS: Separately it was stated definition on the EUS biliary drainage procedures and it includes the techniques details and critical analysis. CONCLUSION: Hepatico- gastrostomy and Choledocho- duodenostomy are feasible when performed by endoscopists with expertise in bilio pancreatic endoscopy and advanced echo-endoscopy and should be performed currently under rigorous protocol in educational institutions.
