 At that time I reviewed everything, suturing technique, knot tying technique, everything. For those of you who are coming here for the first time, anybody coming for the first time today? Yeah. So I'll just give you a brief outline of the... Is it rolling now, Cameron? It's rolling. You look great. You do, maybe. I haven't played it through. Okay. So for those of you who have come today, this is a needle. There are two types of needles. One is a cutting needle. Other is called a round-body needle. How do we determine a cutting needle or a round-body needle? It depends on the cross-sectional appearance. Suppose you were to take a cross-section through this needle, and if you were to look at it end-on. If it appears triangular in shape, then it is called a cutting needle. And if you were to take the same cross-section and you were to look at it end-on and if it appears circular in shape, then it is called a round-body needle. So the next question is when do we use a round-body needle and when do we use a cutting needle? A round-body needle is used for delicate structures like peritoneum, mis-entry, intestine, all these conditions we use a round-body needle. And when do we use a cutting needle? We use it for tough structures like the skin. We use it for the rectus sheath. We use it for the linear alba. So for these structures... So since this is the mimicking of the skin, so we shall be using a cutting needle for this. This is supposed to mimic the skin condition. Okay, so this time I'm going to... Though this is a skin, but we usually use this continuous technique as he showed in the second video. We use it on the linear alba. After you have done a laparotomy, you have done whatever procedure you had to be done and you said first you have to close the linear alba. The linear alba is a tough fibrous layer which is in the middle line. Where all the fibres mesh in the middle. So let's assume that this is the linear alba. So before we start with the procedure, let me remove all these knots here. The first step is we have to take a biteful thickness as usual. And assume this is the linear alba. And you take a full thickness bite on the other side without taking your needle out. Push it, grab hold of this end and pull it out. Always remember there's always an assistant on the other side who's assisting you. Take double throws. Put the first knot. See how quickly silk tends to slip. Silk is notorious for slipping. Nylon, all these things. Make sure we have taken multiple throws so that it is firmly embedded. What would you recommend on that? For which one? For the silk though. What would you recommend? This is nylon, not silk. For nylon then? Yes. So after you've taken multiple throws and you've firmly embedded the knot, what we do is in actual practice, the end which I'm holding now, we just put an artery for silk like this and we put it to one side. But now I can't because I don't have an artery for silk. Now the next job will be, assistant should give constant traction on this end so that it doesn't become loose. So since there's no assistant, I'm going to show it to you without, I'll just do it myself. I'm going to lift it up like this and I'm going to take another bite next. Full thickness, other side. Full thickness, other side. And now I'm going to just continue. Assistant has to keep giving traction otherwise this will tend to become loose. Next, I'll continue with the procedure to take another bite and take the next bite. See, things will now start coming obliquely. Just keep following. Assistant is giving constant traction here. Next bite and a full thickness bite to the other side. See? Now this suture line will come slightly obliquely. This is how we close the linealba. Next bite. There we go. It should be almost evenly spaced out and they should be roughly parallel with each other. When you reach the end I'll show you how to finish the knot. That is a little tricky. So let me continue till we reach the end. I want to finish now because the loop is becoming very small. I'll have to tie a knot. So this is where I'll finish. I'm assuming that I've reached the end of my linealba. So now what I'll do is I will not completely tighten this. Instead I'll keep it a little loose here. This one I'll keep it a little loose. Now watch. I'll loop here and I catch hold of this and I pull. And it becomes a knot. Then again I take the reverse. Catch hold of the tip here and I pull. And it becomes a knot. Then I catch here. Put multiple throws. There we go. And we are done. So I'm assuming that we have reached the end of our linealba and we cut it off. This is the procedure for doing a continuous suture of the linealba which they showed here. They showed only the first two steps. This is how we complete the whole thing. So now all of you start.
