Cholecystectomy is a common surgical procedure, of which laparoscopic cholecystectomy is the most common, which is a minimally invasive surgical procedure commonly used today, with the characteristics of less trauma, less pain and faster recovery. The preoperative preparation for cholecystectomy is relatively simple, as follows: 1. The main point is that you need to abstain from eating and drinking for 6-8 hours before surgery to avoid reflux into the trachea and lungs during surgery. 2. Attention should be paid to the preparation of the surgical area, mainly for male patients. 3. Other related preoperative preparations include taking down the dentures, which are often referred to as dentures, and removing the metal jewelry worn in the body. 4. 4. The urine in the bladder should be drained before surgery, because most cholecystectomies require a short operation time and do not require a urinary catheter. These are the most important and common preoperative preparations for cholecystectomy.
