Drugs that do not enter the duodenum after laparoscopic cholecystectomy are bile ducts blocked?

Question
Hello doctor,
My father went to laparoscopic cholecystectomy and placed a drainage tube for 50 days, but now he goes back to the doctor to take a CT scan and inject contrast, the image cannot be seen through the duodenum. The doctor asked me if the medicine does not go into the duodenum after laparoscopic cholecystectomy, is it blocked the bile ducts? Is there any way to get bile into the duodenum, doctor? Thank you doctor.

Hello,
With the question “Does the medicine not go into the duodenum after laparoscopic cholecystectomy, does it have to block the bile ducts? ", the doctor would like to answer as follows:
In case the drug does not pass into the duodenum, it is necessary to find out to rule out the cause of obstruction in the lower part of the biliary tract (lower part of the common bile duct and the sphincter of Oddi). In your father's case, after laparoscopic cholecystectomy, it may be accompanied by removal of the main bile duct stone (common bile duct) or other abnormalities, so a biliary drainage (T-drain or Kehr's drainage) was placed.
Patient needs to be reassessed by the surgeon for biliary drainage, possibly requiring endoscopic retrograde cholangiopancreatography (ERCP) to manage the cause; or endoscopic cholangioscopy with a flexible bronchoscope through the Kehr tunnel. After the bile drains into the duodenum, the Kehr drain is withdrawn. Therefore, you should take your father to see the doctor again for specific advice.
If you still have questions about the medicine that does not pass into the duodenum after laparoscopic cholecystectomy, you can go to the hospital of Vinmec Health System for further examination and advice. Thank you for trusting and sending questions to Vinmec. Wishing you lots of health.
Best regards!
