I assume you mean hiatal hernia. Which is a hernia in the hiatus in the diaphragm.
The muscle that assists in your breathing, called the diaphragm, is generally the separator between your chest cavity, and your abdominal cavity.
Your esophagus which runs from your mouth to your stomach has to pass through an opening in your diaphragm. That opening is called the hiatus.
There are several reasons this area can weaken, and when it weakens it can allow the stomach and esophagus to start to try to push up through this
area. The other kind of hernia is where a part of the stomach other than described above push up through the affected area. The hernia itself is in
the muscle though...your diaphragm.
Generally, a small hiatal hernia causes little or no symptoms, and requires no surgery. Surgery is generally reserved for people who have a very large
hole that has either been ignored, that has opened pretty quickly,or for people who have not responded well to other treatments. OR for people who
have the second kind described above called a paraesophageal hernia. Generally initial treatments involve such things as antacid medicines and treat
the effect, not the cause.
What concerns me here, is your doctor saying it is inside your stomach.
Larger hiatals can cause stomach acid to back up into your esophagus. This can lead to an eroding of the esophageal lining and/or the area right at
the stomach/esophagus sphincter. This may mean what he means by that. This is not good if that is what is happening, as eating away your esophageal
lining is bad. Also, in the paraesophageal hernia situation, this can cause the stomach to lose part of it's blood supply. This also is bad.
You need to have him clarify to you what exactly he is fixing, and which form of a hiatal hernia it is. In the above scenario, they would still
surgically repair the diaphragm in order to stop the erosion, but they would also have to fix the ulcer that is being caused by the acid buildup.
Not trying at all to diagnose you, or scare you here. I'm just trying to understand what exactly is wrong with you. Some good info on hiatal hernias
can be found here:

Surgery is generally done laparoscopically, and there is minimal invasion.
Recovery is usually pretty quick for this as long as there is no heavy lifting involved. Usually in about a week. Since you said you were in Europe,
usually around 10kg is the maximum they may allow you to lift for 3 months after surgery. Also, unfortunately, there is no guarantee that the hernia
won't come back later on. That doesn't mean you shouldn't still have this fixed now.
If you have more questions of me, or find out some more, please feel free to ask away.
