The drainage tube can be removed about 2 weeks after the above two operations. Your father was discharged from the hospital with a tube, which means that there are stones in the biliary tract or it is not very smooth. Doctors need to observe before further treatment. This kind of operation must strengthen nutrition, otherwise it will easily lead to complications such as bile leakage due to malnutrition affecting wound healing. Dr. Xin Kui will operate in time, or your father's life will be in danger.
This situation is not a medical accident. I can understand your feeling. Please cooperate with doctors, actively treat, control infection, strengthen nutrition intake, and promote the improvement of father's own resistance.
I wish your father a speedy recovery!
