Hi Ussher, I'm an Endoscopy nurse, so I can help you with any information you want.
First of all it's a Gastroscopy you're having, that is a look into the oesophagus, stomach and duodenum with a flexible endoscope (telescope). The test takes about 4 minutes to perform, and can be done under sedation (not anaesthetic) or Local anaesthetic throat spray, which works very well, but tastes awful. The sedative that is used in my hospital is called Midazolam, and it is part of the Benzodiazepine group of drugs. The effect you get is a drowsy confused sort of state, and you are very forgetful for a while afterwards. If you are having an afternoon appointment, you should be aware that you are not legal to drive for 24 hours, so should be off work the next day.
If you choose sedation you will require a recovery period of an hour or so before you will be allowed to go home, and a lift home is a must as is somebody to stay with you overnight.
The endoscope is about the width of you little finger, and your oesophagus and your trachea are completely separate, so choking is not going to be a problem. The worst bit is when the scope is touching the back of your tongue, and it's normal to retch a wee bit until it progresses beyond there, once it's on it's way down your oesophagus you will feel more comfortable.
If you have dentures, they will be removed, and if you have natural teeth, a plastic mouth guard will be placed between your teeth to stop you from biting the £35,000 worth of equipment.
It's routine to have at least one biopsy taken, called a Clo test, to test for the presence of helicobacter bacteria.
If there's anything else I can help you with, please ask, you'll be fine, I promise. :)
