Advanced gives significant advantage in my opinion in job search. More and more seniors with ERCP certification are retiring. Many private practices dont want ppl doing EUS coz compensation is less, it takes more time, anaesthesia support, etc. you can always negotiate about building an EUS practice(management should be willing to invest in the equipment). Its not completely waste - it makes you more rounded GI and if you really have the passion to be an advanced endoscopist(which I am not), you should do it regardless of the job proposition. there will be a lot of ERCP need going forward
