Minimally Invasive Surgery

Minimally invasive surgery is becoming more and more common in hospitals. The performance of minimally invasive instruments and equipment is through small incisions. Because of the small incisions, patients tend to have faster recovery time and less discomfort compared with traditional surgeries. In minimally invasive surgeries, surgeons would use minimally invasive equipment to make several small incisions on the skin (in some cases only a few millimeters) and a thin tube (called an endoscope) with a micro-imaging display lens connected at one end to pass through one of the incisions. The image of the endoscope is projected onto the monitor of the operating room, so the surgeons can see the operating area clearly (magnified), the endoscopic retrieval bag will be used later.


These instruments allow surgeons to explore, remove, or repair any problem parts in the body. In some cases, patients may be arranged for minimally invasive surgery, but after being viewed in the body, surgeons may have to "switch" the operation to an open (conventional) operation. This may be because the problem or anatomical structure is different from the surgeon's expectations. Minimally invasive surgeries have more advantages than traditional surgeries. Because of the small incision, patients would not suffer severe pain, and have smaller scars that can recover more quickly compared to conventional surgeries.
