What is the principle of laparoscopic repair of hernia?
We can imagine a bathtub. When we put the rubber stopper at the outlet and fill it with water, the water pressure pushes the stopper in place and keeps it fixed there. The more the water, the firmer is the stopper. Now, if we were to put the stopper from the outside. Then the water pressure in the tub is going to push the stopper out as the pressure increases. This is Pascal’s law.The same scenario can be imagined with placing a mesh on the hole where the hernia is. Is it going to be better fixed from outside or inside? Open surgery places it from outside and laparoscopic surgery places it from inside.
