Liver cyst surgery is generally named as de-topping, which removes the top of the liver cyst and allows the cyst fluid to drain into the abdominal cavity to achieve the purpose of no further growth, so the surgery is very simple and generally minimally invasive. The operation is usually minimally invasive. The laparoscope makes three holes, two 5mm holes and one 10mm hole, so that the top is removed and the cyst fluid is aspirated, allowing the cyst fluid to drain into the abdominal cavity, and the operation is over in half an hour. However, in some patients, the liver cyst is in a special location, such as in the right posterior lobe or at the top of the diaphragm, which is close to the diaphragm, and it is easy to seal the open hole with the diaphragm after surgery. In this case, partial hepatectomy along the cyst wall can be performed as appropriate, and the operation takes relatively longer, maybe 2-3 hours, but the result is more thorough.
