The tube can be removed once 1) the patient has recovered from the contributory underlying illness, 2) a catheter cholangiogram has confirmed cystic and bile duct patency, and 3) the tube has drained for a minimum of 3 weeks (Wise et al, 2005).
The last requirement is to ensure maturation of a tract around the tube in order to reduce risk of bile leakage and associated peritonitis and/or sepsis. To this end, some have advocated tract imaging prior to removal. However, this may not be necessary "in patients with small-bore gallbladder catheters [e.g., 8-French] who have recovered from critical illness, show patent cystic and common ducts, and have had catheters for 3–6 weeks." (Wise et al, 2005).
In patients with calculous cholecystitis, percutaneous gallstone extraction may be performed before tube removal.
