There is a special feeling in the navel, and everyone is vaguely anxious that "bad things will happen if they are cut." The navel is a remnant when the fetus and the mother are connected by the umbilical cord (umbilical cord). The fetus is immersed in amniotic fluid and cannot breathe or eat. Therefore, the oxygen and carbon dioxide are replaced through the umbilical cord through the umbilical cord, and nutrition is obtained. The blood flowing through the umbilical cord enters the body from the navel of the fetus and goes around each organs. In fact, in our body, there is a "remnant" of a tube that connects the navel, liver, navel and bladder. These are called "liver circular" and "native umbrella", respectively. The inner cavity has already been closed and has lost its function after birth, but it was once a tube that connected the life of a fetus in the mother. After birth, navel is no longer necessary because you can breathe and eat with your own mouth. There is no big problem even if you cut it with surgery, and you may cut it out for some reason. There is an old story that if you do not hide the navel on a thunder day, you will be removed by the demon, but it is actually a "structure that can be taken." In addition, the navel was originally a part of the abdominal cavity and the exit where the outside was connected, so hard muscles and fascia were partially missing. Therefore, the walls are the thinnest and easy to reach the abdominal cavity. In that respect, the navel is the best hole to open in surgery. Now, in general laparoscopic surgery, first make a hole in the navel, insert a cylindrical device called a trocker, and insert the camera from there. While observing the stomach, make some other small holes and insert a trocker as well. -The same as Takae Kagiri, he looks at the video reflected on the camera and performs surgery in his stomach using a magic hand -like equipment (forceps). The principle is the same as "Takae Kirisami". Since the body is dark, the tip of the camera has a strong light source. This light illuminates the body brightly, enabling surgery. In the past, "laparotomy", which cuts straight in the middle of the stomach, was common. In recent years, laparoscopic surgery has rapidly spread, and many surgery has been performed with cameras. The work performed in the stomach is the same, but there is an advantage that using a high -quality camera can perform surgery under detailed proximity image that exceeds human eyes. Furthermore, it is a great advantage that the camera can enter the back of the stomach, which was hard to see even if I looked into it so far, and provide a clear view to the surgeon. Similar methods are widespread not only in the stomach but also in the surgery in the chest. This is called a thoracicoscope, but the mechanism is the same. Even in a narrow and deep space surrounded by ribs, the camera sneaks into it and provides definite images. Surgery performed by inserting a camera into the body, such as laparoscopes and thoracicoscopes, is generally called "endoscopic surgery." Endoscopic surgery was the first in the world in 1980, and the first surgery to remove gall bladder. The accuracy of the camera has been remarkably advanced, and the organs that can be applied year by year have expanded, and can now perform endoscopic surgery in almost all the organs in the chest and stomach. However, there are still cases where laparotomy and thoracic surgery is required, and such surgery is not gone. Although endoscopic surgery is increasing, the current situation is that it is used properly with conventional surgery according to the condition of the disease.
