Could be: most of the time endometriosis is located in the pelvis,mostly the pain usually lower abdominal pain gallbladder located in the RUQ of the abdomen can produce pain in upper abdomen,middle abdomen,and can cause lower abdominal pain,and chest pain. the question why you are having ERCP,usually there is a specific indication for that test.like jaundice or evidence of stone in the common duct.
