Obstructive jaundice is not harmful

There are many diseases that can occur in the human body, but the mechanism and symptoms of different diseases are different, such as jaundice, which is an internal tissue disease that is difficult to detect with the naked eye, and its local manifestations are yellowing of the skin surface, etc., jaundice has many categories, including obstructive jaundice, many people don't know him, some people say that it is not harmful, so is obstructive jaundice harmless?

Obstructive jaundice is jaundice caused by obstruction of the extrahepatic bile ducts or intrahepatic bile ducts, the former is called extrahepatic obstructive jaundice; The latter is called intrahepatic obstructive jaundice.

The skin is dark yellow or greenish-brown, and there are many scratches due to the retention of bile salts in the blood and irritation of nerve endings in the skin. Due to biliary obstruction, bile cannot enter the intestine, the stool color becomes pale or clay-colored, and urobilinogen is reduced or absent. After biliary obstruction, the lack of bile acids, cholesterol, etc. in the intestine, coupled with the deficiency of fat-soluble vitamins, can be clinically manifested as steatorrhea, skin yellow warts, bleeding tendency, osteoporosis, etc.: patients with cancer obstruction can still have Courviosier sign.

For patients with a clear diagnosis of liver cancer, the diagnosis of this disease is not difficult, and patients with liver cancer have yellow staining of the skin, sclera, and urine, and the concentration of bilirubin in the blood increases, or there is no yellow staining of the skin, sclera, and urine, and only the concentration of bilirubin in the blood is elevated. The conjugated bilirubin in the blood was significantly increased, the urine bilirubin was positive, the skin was itching, and the stool was white clay-colored, which was obstructive jaundice; Serum conjugated bilirubin and unconjugated bilirubin were elevated, with conjugated bilirubin being the main body, urinary bilirubin positive, urobilinogen increasing, and hepatocellular jaundice.

For patients with unclear diagnosis of liver cancer and jaundice as the first symptom, the diagnosis of this disease is difficult. Must be associated with bile duct cancer. Differentiation of pancreatic head cancer and duodenal ampullary tumors, jaundice of liver cancer often has hepatitiscirrhosismedical history, appearing in advanced liver cancer, accompanied by right upper quadrant distension pain, and often elevated blood AFp concentration; However, most of the bile duct cancer, pancreatic head cancer and duodenal ampullary tumors have no history of hepatitis and liver cirrhosis, and only painless progressive jaundice is the first symptom, the blood AFp concentration is mostly normal, and abdominal B-ultrasound, CT, MRI, pTC (percutaneous puncture hepatic cholangiogram), ERCp (endoscopic retrograde cholangiopancreatography). Tests such as radioclide cholangiography and angiography can help distinguish the above diseases.

There is a type of pseudojaundice called carotenemia, which is caused by too much carotene intake or insufficient thyroid function, which makes the skin look yellow, but it is not true jaundice and must be distinguished. In addition, residents living near the sea often have yellow and red eyelids on the whites of their eyes due to the sun and wind, which can be mistaken for jaundice in the sclera.
