AIM:To report our experience using a recently introduced anchoring balloon for diagnostic and therapeutic direct peroral cholangioscopy (DPOC).METHODS:Consecutive patients referred for diagnostic or therapeutic peroral cholangioscopy were evaluated in a prospective cohort study.The patients underwent DPOC using an intraductal anchoring balloon,which was recently introduced to allow consistent access to the biliary tree with an ultraslim upper endoscope.The device was later voluntarily withdrawn from the market by the manufacturer.RESULTS:Fourteen patients underwent DPOC using the anchoring balloon.Biliary access with an ultraslim upper endoscope was accomplished in all 14 patients.In 12 (86％) patients,ductal access required sphincteroplasty with a 10-mm dilating balloon.Intraductal placement of the ultraslim upper endoscope allowed satisfactory visualization of the biliary mucosa to the level of the confluence of the right and left hepatic ducts in 13 of 14 patients (93％).Therapeutic interventions by DPOC were successfully completed in all five attempted cases (intraductal biopsy in one and DPOC guided laser lithotripsy in four).Adverse events occurred in a patient on immunosuppressive therapy who developed an intrahepatic biloma at the site of the anchoring balloon.This required hospitalization and antibiotics.Repeat endoscopic retrograde cholangiopancreatography 8 wk after the index procedure showed resolution of the biloma.CONCLUSION:Use of this anchoring balloon allowed consistent access to the biliary tree for performance of diagnostic and therapeutic DPOC distal to the biliary bifurcation.
