MEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEEE
There isn't a person on this site who could possibly know more about endoscopy than me. Including any proper docs!
The test they want to do is an OGD - it involves getting a camera the diameter of your index finger and pushing over your tongue and down your throat. Thats the worse part of the procedure - the first 10 seconds. It then goes down your food pipe, and can look for tell tale signs - a hiatus hernia, redness in the food pipe both indicate that acid might be coming up your food pipe where it shouldn't.
Then into the stomach and the first bit of your small bowel.
H.pylori is a bacteria that can live in your stomach and duodenum and cause you to feel ill. some people ahve it and are fine, but in many it causes ulcers. it actually causes over 90% of duodenal ulcers.
Theres a few parts of the stomach where if you do have this bacteria then it will likely be. so they take a small piece of tissue (using a tiny claw in the camera bit) - you don't feel this by the way. (they could cut chunks off you and you wouldn't know - you can't feel pain there). they then take the camera and pieces of flesh (biopsies) out.
Whole thing takes no more than 3-4mins.
The biopsy is put ina little plastic thing with some urea and litmus solution. if the bacteria is in your stomach (and hence the sample) then it will make the solution go red. The results of this are very quick - if not within a few hours, then within a day. they team will tell your gp the result, and he will treat you accordingly. If you DO have H.pylori then they will give you a weeks worth of antibiotics to clear it - and it shouldnt ever come back.
AS for the procedure, there are two ways to do it.
One with just some throat spray that numbs your throat.
Or you can be sedated (relaxed) with a drug called medazolam. Note you WON'T be knocked out. you'll be awake throughout the procedure.
if you want sedating you'll need an injecion, and need someone with you to take you home as you'll be really dozy/sleepy afterwards.
throat spray you can go on as normal - tho you cant eat or drink for 45 mins afterwards.
Some peoiple are fine with just throat spray, some fine with sedation, others buck and fight and gag with max sedation (rarely though!). its quite random, there is no way of predicting it.
Anymore questions about it let me know.

PS if you are having it done in Kings hospital then I'll see you soon lol.
