Obstructive jaundice is a type of jaundice, and the clinical manifestations of jaundice are yellowing of the skin and yellowing of the eyes. Because Asians are yellow, a slight yellowing of the skin is not easy to detect, and it is important to observe the patient’s eyes to see if there is jaundice in the sclera, and to ask the patient if there is yellow in the urine. Patients sometimes have uncomfortable itching and scratch marks all over the body. This is often seen in patients with obstructive jaundice, which can be seen at first glance. The patient will have generalized jaundice, itching and scratching of the hands and feet, and a yellow sclera of the eyes. When asked about the patient’s medical history and the volume and color of the urine, the patient will describe how the urine was yellow at the beginning and felt increasingly yellow, or even had a soy-like change in the urine. In patients with obstructive jaundice, if the obstruction is caused by a benign stone or a benign surrounding lesion, the patient’s nutritional status is more normal. If the obstructive jaundice is caused by a malignant tumor, it may be combined with malignant manifestations. In addition, patients with obstructive jaundice may develop chills and fever when they have a co-infection. If a patient has obstructive jaundice combined with abdominal pain, chills, and fever, it can be basically determined that the patient has biliary tract infection caused by bile duct stones, resulting in obstructive jaundice. If the patient presents with progressive jaundice, painless, progressive jaundice can be clinically suspected as a malignant tumor, an obstructive jaundice caused by a tumor in the lower part of the common bile duct or around the periampullary region, or a tumor in the hilar region.
