I have IBS and recently had my gallbladder taken out. The dr said the gallbladder was not functioning. Upon taking it out he said it appeared leathery, hard, etc. Well a few weeks after my liver enzymes increased i had chills,rash,night sweats, delirium from this. GI doctors didnt know what was wrong with me. I dont drink, nor do i have any form of hepatitis. So im having an e.r.c.p done this week. Dr thinks its the sphincter of oddi. How effective is a stent, will this correct the upper right pain, nausea, vomiting im having? The pain is unbearable.
