Before cholecystectomy surgery, it is necessary to check the gallbladder and also for the physical condition. 1. Gallbladder-related examination: mainly abdominal ultrasound, abdominal CT scanning, if necessary, should be further magnetic resonance cholangiopancreatography, for the surgical site, to be able to clarify the severity of the disease, to understand the difficulty of surgical operation. 2. Patient’s own examination: it mainly includes blood routine, biochemistry, coagulation, chest X-ray, electrocardiogram, and relevant examination combined with past disease history to clarify whether the patient can tolerate the surgery. The above examinations before gallbladder surgery are to reduce the risk of surgery and to ensure the prognosis of patients. When preparing for surgery, patients need to inform the doctor in detail about their basic medical history to facilitate the doctor’s targeted examination.
