This information explains how to do a capping trial on your biliary drainage catheter.
Back to topAbout Capping Trials
Your doctor may want you to do a capping trial on your biliary drainage catheter. This is done to make sure bile (a fluid made by your liver) can flow easily through your body and to make sure your bile ducts are open.
Capping your catheter helps your bile travel down the catheter into your body so that you will no longer need a bag (see Figure 1).

Your nurse may cap your catheter for you while you’re in the hospital. You will need to do it yourself when you’re home.

- Gather your supplies. You will need:
- An alcohol wipe

- Disconnect your stopcock from the drainage catheter (see Figure 2).

Remember to flush your catheter on the same schedule through the needleless connector.
Back to topWhile Your Catheter is Capped
If you have a capped biliary drainage catheter, you need to watch for these symptoms:
- A fever of 100.4º F (38º C) or higher.
- Leaking around your catheter insertion site.
- Pain around your abdomen (belly) where the catheter is.
- Chills.
These symptoms can happen any time after your catheter is capped. If you have any of these symptoms, call Interventional Radiology and then, uncap your catheter. To do this, remove the needleless connector cap from the catheter and reconnect the catheter to a new drainage bag. Your symptoms should go away within 30 to 45 minutes. If they don’t, call Interventional Radiology.
Do not recap your catheter without calling Interventional Radiology.
