Cholangitis is an inflammation of the bile ducts caused by bacteria from the bowel . This is a common problem after a Kasai, because bacteria is present in the loop of the intestine used to correct the biliary system. Medical attention should be sought immediately, because if left untreated, it will cause damage to the liver and the remaining bile ducts. Blood tests and a liver biopsy are necessary to confirm the diagnosis. Treatment is IV antibiotics, because it enters the bloodstream rapidly and gets to the liver.
Hospitalization is required, usually lasting a week or two.
As the liver becomes scarred, it presses against the walls of the veins. This constricts the veins and the normal amount of blood cannot pass through them. Once portal hypertension is present, parents should be aware that varices can develop. Varices occur when veins encounter increased blood pressure which causes them to weaken and expand. Varices can be found in the esophagus, stomach, small intestine and the rectum.
