My father has stage 4 colorectal cancer with mets to the liver. One tumor has recently blocked the bile duct intrahepatically. He got a permanent drain and as a result, his liver enzymes have dropped substantially. However he has acute onset peritoneal fluid that he had drained once already and has filled back up within 4 days. The fluid they drained was yellow and bilic in color. His bilirubin value has shot up from 3.2 (when he became obstructed) to 15 post drain placement. Is it leaking?
