 Welcome to the next section of the Domenical Contents. Dr. Sanjeev Sanyal, today I've dissected out the entire colon, what we call as a total collectivity. Well, that I had done once in my actual clinical practice also, but here we have done it in a cadaver. Just to bring you up to speed, yesterday I had shown you the small intestine, and this is where I had resected the terminal ilium. So this is the terminal ilium where my instrument has gone in. So this is the ilium secret junction that you see here. So therefore, this is the cecum, and this is the sending colon. Before we go any further, Jason here is holding up the rest of the colon. In the meantime, just let me show you a few quick things here. The ilium secret junction, I told you that in the cecum, is the place where all the tinia coli meet and the base of the pendings. In this particular case, we can see one of those tinia coli here. This is the pendings, and one of the tinia coli is here. We can see the tinia coli. So like that, you can see some of these vertical blend of fibers here. This is the tinia coli. So all of these three tinia coli will meet at the base of the pendings, and that is how we trace the pendings. This is the pendings. So this is the cecum. Let's continue further. This is the sending colon. And on the side of the sending colon, which was located here in front of the right kidney, this is the right paracolic cutter, which I told you in the glass. And this is where fluid goes, and it collects in the pelvis. As we trace the sending colon up, this is the region of the hepatic flexure, which was located under the liver. This is the transverse colon. How do we know that this is the transverse colon? We can see that this is the great momentum here. This was hanging down like this. And furthermore, this is the cut edge of the transverse meso colon. It was attached here. It was across like this. So I've got it here. So this is the meso colon, the transverse meso colon, which is the only one of the two parts of the colon, which has got a mesentery. And this is the great momentum. This great momentum was hanging down like this. Continuing the transverse colon, we can find that this is the region of the spleen. So this is the region of the spleenic flexure. Can you bring your hand on a little bit? This is the region of the spleenic flexure. And after that, this is the descending colon. The descending colon also, I cut just a little before the sigmoid to show you how the sigmoid is disposed. And you can see the sigmoid is really S shaped. It is going like this. It is going like this. And it is going inside and becoming part of the rectum. This portion is dilated for some reason. I don't know why. So this I have cut. This is actually still part of the descending colon. The sigmoid starts from here and it goes up like this and you can see it is hanging on a mesentery. So therefore, this is the sigmoid. This is the meso sigmoid. So till this much was the descending colon. So this is the whole length of the colon. We can see these structures here. These structures that you see, you can see them much more clearly. These are known as appendices epiploike. And we can have a clinical condition that these can get necrosed and that is known as epiploic appendicitis. So we can see the appendices epiploike. We have seen the tinnia coli. The tinnia are named according to their relationship with the transverse mesocolon. The tinnia which is in relation to the transverse mesocolon is known as the tinnia mesocolica. The tinnia which is in relation to the great romatum is known as tinnia oventalis. And the third set of tinnia which is neither here nor there is called tinnia libera. And the same tinnia continues on both the tinnia coli as well as the descending colon. So this is in brief. And that's perhaps the only thing which I wanted to show you about the transverse colon. Now what I'm going to do is I'm going to remove the entire colon from here. And I'm going to give you a quick overview of the rest of the domino structures. What you see here, this is the stomach. You can see this is the fundus of the stomach which is under the left dome of the diaphragm. This is the greater curvature. And these were the epiploic or the gastromental vessels which I have cut here. And this is where the great romatum was hanging down which you held up just now. This is the lesser curvature of the stomach. And you can see the lesser romatum here. You can see it under the light here. This is the lesser curvature and the lesser romatum. This is the membranous part, the thin part of the lesser romatum. And this is the thick part, the so-called hepatodeodonal part and I'm holding the three structures of the portal tried in my fingers. And you can see they're going towards the liver. Continuing the stomach, we can see that it is continuing as the diodenum. And this is the sea loop of the diodenum here. This is the sea loop of the diodenum. And yesterday I had removed the small intestine at the DJF fracture here. So what is located within the sea loop of the diodenum? And you can see the pancreas. This is the pancreas. This is the pancreas here. This is the pancreas. But I'm going to dissect out the whole thing. So this is the head and the ulcerative process. This is the body and the tail of the pancreas will go further towards the spleen. So this is the pancreas, which is located within the sea loop of the diodenum. What is in relation to the stomach? Especially the fundus of the stomach. There. You can see the spleen there. So this is where we had the splinic flexure. Okay. What else do we see? Imagine the anti-abdominal wall was there. So this is the phalseiform ligament. And this is going and attaching to the liver. So this is the phalseiform ligament. It's a fracture of the liver. One end was attached to the abdominal wall. Other end is attached to the liver. And the free margin. And if you're feeling the free margin, you can feel the round ligament of the liver. So this is the phalseiform ligament. And that divides the supra-subphrenic recess into a right compartment and a left compartment. This is what I mentioned in the glass. The phalseiform ligament separates. Under the liver, we can see this is the gallbladder. The gallbladder, most of it is under the liver. A little bit of it protrudes out. And this is what you can see the gallbladder. What else do we see? Apart from the pancreas, which I have already shown you, you can see the right kidney here. This ascending colon was on top of this. And you can see part of the left kidney here. The descending colon was descending down like this. A little bit of it you can see here. You can see the inferior vena cava here. And you can see the abdominal aorta here. So these are the structures which I'll dissect out over the subsequent few days. So that is all for now. Thank you very much for watching, ladies and gentlemen. Have a nice day.
