What is the cause of bile excretion obstruction?

summary

Once the extrahepatic biliary system tumor or stones, will be biliary obstruction, bile can not be smoothly excreted, and obstructive jaundice. When the biliary system is obstructed, the excretion of bile is hindered and bilirubin is returned to the blood, which is called obstructive jaundice. The site of obstruction may be intrahepatic or extrahepatic, with complete or incomplete obstruction. The common causes include capillary bile duct hepatitis, cholelithiasis, liver cancer, cholangiocarcinoma, pancreatic cancer, biliary ascariasis, etc.

What is the cause of bile excretion obstruction?

1、 It is a benign cause, such as the most common (1) bile duct stones or gallstones, stones block the bile duct, resulting in bile can not be discharged into the duodenum（ 2) Patients with chronic pancreatitis form pseudotumor in the head of pancreas, which compresses bile duct from outside to inside（ 3) Biliary stricture due to inflammation or surgery（ 4) Other such as rare biliary bleeding, blood clots blocked the bile duct, resulting in jaundice; Clonorchis hepatica or worms mistakenly entering biliary tract.

2、 (1) malignant tumor of bile duct or gallbladder (cholangiocarcinoma) (2) carcinoma of pancreatic head (3) carcinoma of Vater's ampulla (4) obstruction of bile duct by liver cancer plug (5) obstruction of bile duct by enlarged lymph nodes adjacent to bile duct in cancer patients.

Bile reflux gastritis, also known as alkaline reflux gastritis, is a series of syndromes which are caused by bile back to the stomach, such as upper abdominal pain, vomiting, bile, abdominal distention and weight loss. It is commonly seen after gastrectomy and gastroenteric anastomosis. The total incidence rate is about 5%. Among them, the incidence rate after Billroth II gastrectomy is 2~3 times that of Billroth I. In view of the differences in symptoms, pathological changes and treatment response between the two groups, Roberts et al. Classified the disease as an independent disease from the complications after gastrectomy.

matters needing attention

In the treatment, Chinese medicine according to Huangdi "Neijing". The six Fu organs in the chapter of five zang organs bielun can not be filled because they are passed on but not stored. The later doctors have the theory that the six Fu organs are used for unblocking. Therefore, the treatment of obstructing jaundice is mainly based on the principle of dredging, clearing and unblocking. According to the syndrome differentiation, the different syndrome types are treated as follows: Yinhu mixture (clearing heat and dampness, benefiting gallbladder and leading stagnation), Niuhuang Wuhua powder (clearing heat and cooling blood, benefiting gallbladder and detoxifying), yinchenzhu Fu Decoction (warming middle and resolving dampness, benefiting gallbladder and leading stagnation) For the treatment of obstructive jaundice, dampness and blood stasis are the main causes. Therefore, removing dampness and diuresis, dredging the Fu organs and removing blood stasis are the important treatment methods.
