it sounds like you had a bile leak, rather than a true abscess. This can come from various sources, either an aberrant bile duct draining from the liver right into the gallbladder, or from injury to the main bile duct, or from the duct that went from the gallbladder to the main bile duct. The treatment you had should eventually take care of it. Assuming what's coming out the drain is bile, or at least bile-tinged, what's usually done is wait til the fluid no longer contains bile, and then remove the drain. The abdominal cavity can absorb quite a lot of fluid of various types back into the bloodstream, even a small amount of bile. So one almost never waits until drainage is zero, because it may never be. What's important is that the bile leak heals; which in the vast majority of cases, it will. I'd think the radiologist wouldn't pull out the drain without first consulting your surgeon.
i am going thru a similar situation, had gallbladder disease without gallstones. after about 11 tests, the 2nd hida scan with contrast showed 0% input & output function & the gallbladder was a dead organ. had gallbladder removed thru laproscopic surgery on 9-19-03, had 10 days of no symptoms, at most mild phantom pains, on the 11th day the same pre-surgery pain resumed in full force. today 10-21-03 going back to internal surgeon. my gi dr said the surgeon may have nicked an organ or duct or i may have residual bile sludge/bile leak. pre-surgery i was having gallbladder attacks indiciative of gallstones... no tests showed gallstones... i know have the same pains again in my should, right arma numb, severe acid/ bile reflux & spit up solids & liquids 8-12 x's daily with extreme nausea.
how much pain are you in? are your pains identical to pre-surgery pains? did you have abdonimal swelling? any sign of infection?
i am not in pain at all but when the pain came back after a week it was bad pain i had a leak and they put a sten in just my back hurts sone times from the tub and when i over eat it ant good but over all i am doing good going to doc in the morning to get tub out. i hope you do better keep me posted like to here from you and i will leat you know how i am doing thank you 4 your in put

just got out of the hospital again & was diagnosed with a sphincter of oddi disorder, that is the muscle that allows the flow of bile & enzymes from the liver & pancrease to the dueodum (small intestine & stomach juncture) may have caused my gallbladder shut down. i may have to have a stent, bypass or they may have to cut the muscle to allow it to permanently relax, i refuse to do a botox injection every 3 months.
how are you feeling? any better?
