On Nov. 25, 2012, I had my gallbladder taken out due to the presence of multiple stones. Two weeks before, i had the mrcp and the results confirm that there is no stone in the bile duct. The day after surgery, I was informed by the surgeon of NYU that the xray taken during the surgery shows a shaded surgery which could mean the presence of a stone in the bile duct or it could just be the imperfection of the xray. To confirm, I need to have another mri which i did last Friday, Jan. 31st. The surgeon informed me yesterday that indeed i have a 7mm stone in the bile duct and suggested that i should have the stone taken out before i travel on February 18th. If I have the stone taken when i come back to NY on March 31st, what would be the consequence?
