gallstone removal post surgery

[grammydeb]

12 yrs. ago I had gastric banding.  It is a tight band and I was told it could not be removed because it is scarred in.  I now have had my gallbladder removed and after a second surgery still have a stone and debris remaining.  
Are there different sizes of the equipment for ERCP that would allow me to have the stone and debris removed without surgery?  A gastro Dr. tried but his equipment was too large to fit thru the band. Where would I look on the internet for qualified Drs.? or find some type of help?

That does make sense...I wonder what my options are to retrieve them?  After 2 surgeries in the last 4 months I pray that there is some other way.  Thanks so much for your reply.

Grammy, they do make smaller diameter tubes for children, however that equipment is typically shorter in length and it wouldn't reach the area in an adult that it can in children.
