What tests do hepatobiliary tumors need before surgery?

Before hepatobiliary tumor surgery, a series of examinations are required, including hematology, imaging, and cardiopulmonary function evaluation. These examinations help doctors understand the patient's physical condition, assess surgical risks, and formulate appropriate surgical plans. 1. Hematology examination includes blood routine, liver and kidney function, coagulation function, electrolytes, blood glucose, blood lipids, tumor markers (such as AFP, CEA, etc.). These examinations help to understand the patient's general condition, evaluate the surgical tolerance, and predict the nature and malignancy of the tumor. 2. Imaging examinations include B ultrasound, CT, MRI, etc. These examinations help to determine the location, size, adjacent relationship with surrounding tissues, and whether there is distant metastasis. For hepatobiliary tumors, imaging examination is very important for the formulation of surgical plan. 3. Cardiopulmonary function evaluation For older patients or patients with cardiopulmonary diseases, cardiopulmonary function evaluation, such as ECG, pulmonary function test, etc., is needed. These examinations help to evaluate the patient's surgical tolerance and reduce the surgical risk. In addition, depending on the patient's specific situation, the doctor may also arrange other targeted examinations. Before the operation, the patient should actively cooperate with the doctor to complete various examinations in order to fully prepare for the operation.
