I Have Had A Clip Left In After Gallbladder Surgery

I have had a clip left in after gallbladder surgery which detached and lodged in scar tissue under my liver. Also the gallbladder split and stones fell in. I've been told they can identify a mass either clip or gallstone possibly both which has caused an abscess needing 12 days drainage 7 years ago and again this year. I'm currently facing either major surgery to remove or leave in the hope it won't happen again. This year they left me on antibiotics until it got so bad it expanded went down the old drain site and leaked through the skin in lower back
