Question

Could a decrease in total bilirubin in newborns be a manifestation of obstructive jaundice?

Answer

Obstructive jaundice can be caused by various factors, including bile duct stones (CBD), pancreatic cancer, bile duct cancer, duodenal papillary tumors, Mirizzi syndrome, intrahepatic bile duct stones, portal tumors, CBD postoperative thickening leading to narrowing, gastric antrum cancer, and biliary ascariasis. The diagnosis of obstructive jaundice typically requires laboratory tests such as total bilirubin (TSB) measurement, as well as imaging studies such as ultrasound and CT. Treatment methods include cholecystectomy + CBD incision and stone extraction side-to-side anastomosis, Roux-en-Y procedure, radical pancreatic cancer surgery, Oddi’s sphincteroplasty, and BD internal T-tube support.
