The consequences of untreated obstructive jaundice are very serious. In clinical practice, we often encounter patients from rural areas who present with very severe obstructive jaundice, with severe generalized yellowing, chills, fever, temperature up to 40°C, and liver abscesses, a condition that can be life-threatening. Even treatment with the best antibiotics sometimes cannot save the patient’s life. Some severe patients develop liver function impairment and jaundice followed by coagulation impairment, which is also very dangerous. For example, in a case of a patient with obstructive jaundice, 6-7 consultations at the local hospital did not reveal obstructive jaundice, and the patient was in a state of failure at the time of consultation, and after all efforts to resuscitate the patient and recover his physical condition, he was treated with ERCP surgery, but a series of complications such as postoperative bleeding occurred, and after efforts to resuscitate the patient, he is now in good condition. Therefore, patients with obstructive jaundice should come to the hospital as early as possible and not delay until they are critically ill, otherwise there is nothing the doctor can do.
