The method of extracorporeal bile diversion is simple, less traumatic, and more effective in reducing jaundice, but the long-term loss of bile has a certain risk of causing dehydration, electrolyte disorders, and dyspepsia. Extracorporeal drainage can make bile drain to the outside of the body through the drainage tube, reduce the symptoms of jaundice, and can be observed in the outside of the body to observe the amount of bile, color and its composition. Internal drainage and external drainage are the main surgical methods to relieve obstructive jaundice. The large loss of bile in external drainage will lead to severe malnutrition, severe dehydration, electrolyte disorders, anorexia and dyspepsia, etc. If biliary tract obstruction occurs, the patient should be treated with bile ducts. If you have biliary obstruction, you should consult a regular hospital in time, complete the relevant examinations, make a clear diagnosis, and choose the way to reduce jaundice according to your condition.
