 Good day everybody. This is Dr. Sanjay Sanyal, Professor of Department Chair. This is going to be a quick preliminary demonstration of the entry of Domino Wall. More is going to follow just after this. So what we have done, we have reflected the skin before that. This is a supine cadaver. I'm standing on the right side. I'm holding the camera and I'm doing the narration. So there's just a few quick points which I wanted to bring to your attention before we proceed any further with the dissection. So after reflecting the skin, what we had was a thin layer of fat. That is the camper's fascia or the fatty layer of the superficial fascia of the abdomen. And just under that, in certain areas, we can see the membranous layer. The membranous layer is the scarpa's fascia and this scarpa's fascia continues into the perineum where it becomes one of the Scoli's fascia. The superficial fascia has got the membranous layer which is deeper and a fatty layer superficial which is the camper layer. So we have removed most of it. In the upper part, the scarpa's fascia is very thin, the lower part it becomes slightly thick and it merges with the visual light of the thigh down below. The fat of the superficial fascia, it merges with the fatty fibro-fatty tissue of the mones veneris, which is partly being dissected out here. The next point I would like to bring your attention to are these structures which we have held with artery forceps. These are the cutaneous branches of the thoracic abdominal nerves. And we can see a few other nerves on the side also. These are the cutaneous branches. And the next point which I will bring to your attention is, if you notice, this is the location of the liniar alba. This is the location of the umbilicus. And we can see that this particular cadaver had undergone some infra-umbilical midline incision, laparotomy. And we can see the remnants of the sutures, the green material that we can see here. In this connection, I would like to bring to your attention one very important point. After we have opened the liniar alba, due to any reason and when we close it, like they have done in this case, we have to use non-absorbable material. Otherwise, it is likely to give way. If we use sutures, absorbable sutures is likely to give way and it can produce what is known as an incisional hernia. So here we can see, very rightly, they have used non-absorbable sutures and we can see them here. They are extending right from here to here. So this was an infra-umbilical midline laparotomy incision which has been closed with non-absorbable suture material. More will follow after this. Stay tuned. Have a nice day.
