Here's how to perform an appendectomy - don't try this at home!
Having successfully diagnosed the patient as suffering from appendicitis, on entering the operating theatre, the first job is to wash your hands and put on your rubber gloves.
Now clean the area with the antiseptic (the skin's colour is lightened as a result), and place the drape over the top left corner of the patient's abdomen. Dose the victim up with antibiotics and put some blood on the Intravenous Drip.
Now comes the fun. With the skin all germ-free, pick up the scapel and make an incision from the top left of the area to the bottom right, ensuring that the cut is kept as straight as possible. As it starts to bleed, clamp the bleeding areas with the scissor-like clamps and cauterise them with the tool provided (assuming that you know what tools do what, if not look at the manual).
Clean away the blood with the sponge and pull the skin apart with the retractor. The muscle layer below is now revealed. Now repeat the incision and blood-stemming as before.
The next layer contains no blood, so hack and slash it back. Following that is the transverse muscle layer - this has to be cut from top-right to bottom-left. Retract this and you should see the Cecum.
Next, scrape a little fat away from the top-left area using the scalpel, but be careful not to cut it. Now raise the area with a clamp and use the scalpel to make a tiny cut. Cut along the left-hand side of the Cecum in a top-left to bottom-right incision, ensuring once again to keep it straight. As it opens up, take a sample of the liquid that can be seen inside, then use suction to get rid of it. Now raise the Cecum using the hand icon and pack the gap with your gauze. This reveals the appendix.
Click on the appendix with the hand icon to raise it. The next thing you should do is take the gauze from the top tray (it looks like a toilet roll) and drop it under the appendix to prevent it from falling back into its usual hole. Be careful not to slash anything as you'll get poison everywhere, kill the patient, and ruin your overalls.
Grab hold of the side of the appendix with the hand icon and click twice to extend it. Grab the forceps with your shaking hand and click on the extended appendix. Even a skilful surgeon needs a couple of attempts to find the right location. Don't worry if you miss, the patient's anaesthetised, so he won't mind.
Plant a clamp at either end of the mesoappendix artery. Clip a hole in the upper-middle of the appendix. Sew in a suture in the hole. Place a clamp at the top and cut where the forceps meet the appendix.
If you're lucky the appendix should be out and the patient should survive. Slap the organ in the middle to invert the stump which used to be attached to the appendix. Sew in a suture here and you can start to stitch the hole up.
Once you've cleared up, use the retractor to release the various layers of pinned-back fat and skin. Sew up each layer except the last. Skin clips have been use to prevent scarring.
If you're feeling mean you could always switch the anaesthetic off before the patient wakes up. Don't forget to remove all clamps/forceps/scalpels/ digital watches before closing your patient up.
