Obstructive jaundice caused by a tumor in the middle portion of the common bile duct will improve after surgical removal of the tumor to relieve the biliary obstruction. Normal bile is produced by the liver and flows through the hepatic bile duct into the gallbladder for storage. Eating stimulates the flow of bile through the common bile duct into the digestive tract. In patients with tumors in the middle part of the common bile duct, bile cannot be discharged smoothly because the tumor blocks the common bile duct, so obstructive jaundice will result. Patients usually show yellowing of skin, mucous membrane and sclera of eyes, which tends to worsen gradually. For patients with obstructive jaundice caused by tumors in the middle part of the common bile duct, it is necessary to remove the tumors as soon as possible to restore a smooth bile outflow channel, which can help to relieve the symptoms of obstructive jaundice. It is recommended that patients with obstructive jaundice caused by tumors in the middle part of the common bile duct should seek medical treatment in time to avoid missing the best time for treatment.
