Fluoroscopy of gallbladder drains
- Take an initial anteroposterior image including the presumed locations of the gallbladder and common bile duct.
- Infuse iodinated contrast, usually amounting to approximately 5g of iodine (or about 20 ml of concentration 240mg/ml, but can possibly be multiple times more), and note the following:
- Location of the tip of the drain in relation to the gallbladder
- Flow into the duodenum, or most distal part reached.
- Any visible dilatation of the biliary tract
- Any contrast outside the drain or biliary tract, including leakage along the outside of the drain.
- Any visible stones in the gallbladder or bile duct
If the drain is partially pulled out, it can be pushed into place, preferably with a hydrophilic guidewire.
