Generally speaking, liver abscess puncture and drainage is not a major surgery, the operation time is about thirty minutes, but the exact time varies from person to person. At present, patients with liver abscess can choose to undergo percutaneous hepatic puncture and drainage, which is a minimally invasive surgery, less traumatic, and faster recovery, not a major surgery. The operation time is usually about thirty minutes, depending on the severity of the disease, the doctor’s proficiency and other factors. For example, if the condition is serious, the abscess cavity is large and the location of the abscess cavity is complicated, the operation time will be extended accordingly. After the puncture operation, you should keep the puncture site clean and dry, prevent infection, pay attention to a light diet, and rest more, which is conducive to the recovery of the condition.
