My father had a laparoscopic cholecystectomy with a drainage tube for 50 days, but now he goes back to the doctor to take a CT scan and inject contrast, the image does not show 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.
