For many years open abdominal surgery has been the routine treatment for patients with abdominal diseases. Recent advances in minimally invasive surgical techniques have eliminated the need for open surgery for a growing number of diseases. In addition to the most common surgery for the gallbladder and bile duct system, more and more liver diseases can now be treated by laparoscopic surgery. The figure below shows a case of perivascular epithelioid cell tumor of the liver that we treated. According to the traditional treatment method, a 20cm long incision is required in the patient’s upper abdomen, which not only affects the patient’s aesthetics, but also causes long recovery time and great pain in the early stage of the operation, and abdominal adhesion and other problems in the distant stage may also occur. We used laparoscopic surgery in the treatment, only three small holes less than 1cm in the abdomen successfully resected the left outer lobe of the liver without any problem, the wound for specimen removal was only 3-4cm, and the patient was discharged from the hospital 4 days after the operation. There are many similar cases, and more and more patients with liver disease are benefiting from the advances in minimally invasive surgery technology. Preoperative CT showed liver lesions and the images were reviewed six months after the surgery.
