The papilla was rigid and the biliary tract was dilated with sharpening of the distal bile duct, with no obvious cause. There was no bile flow after sphincterotomy, no stone after sweeping the duct with a balloon and the brush did not expand properly when trying to obtain cytologic material. Finally, a plastic stent was placed and purulent bile flowed. Biopsies of the papilla were taken due to the suspicion of tumor infiltration. The next day, the patient had pain in the right upper quadrant and blood tests highlighted mild anemization.enAgedCholangiopancreatography, Endoscopic RetrogradeCommon Bile DuctGastrointestinal HemorrhageHematomaHumansLiver DiseasesMaleSphincterotomy, Endoscopicresearch article33207897open access10.17235/reed.2020.7154/2020https://doi.org/10.17235/reed.2020.7154/2020
