There is no clear cut features that say that the infection remits. I wish to know why was an ERCP done. It is a procedure done to relieve obstruction in the hepato biliary tract. After ERCP if you are piling up the bilirubin
again ( intensely yellow) then a redo of ERCP is most often required.
It helps a lot for the expert to give an opinion if you an type the final diagnosis. Please make some efforts to do that.
