Traditional open surgery involves making an incision in the patient’s abdominal wall. The surgeon observes through his or her own eyes, touches the lesion directly with his or her hands, and then uses his or her hands, as well as instruments, to directly manipulate and complete the surgery, with the touch of his or her hands throughout the entire procedure. The incision is usually larger and the patient has a longer recovery time. Laparoscopic surgery involves making several small holes in the patient’s abdominal wall, then inserting a laparoscopic lens through the holes into the patient’s abdominal cavity, and transmitting the intra-abdominal lesions through the lens to a display screen. The doctor can see the organs in the abdominal cavity through the display, and then insert the necessary instruments through several other small holes to complete the surgery, the entire operation without the touch of the hand. The incision is small and the patient recovers quickly.
