Coming from someone who had an umbilical hernia repaired, it’s not that bad, but this is just my experience and what I can tell you so far. I’m about eight months post-op, laparoscopic with mesh and absorbable fixation, and the only problems I’ve experienced were some tightness in my abdomen for the first two months. It was pretty rough tbh. All is well right now and I hope it’ll stay that way.
Keep in mind that most of the mesh complications are from inguinal hernia repairs, anatomically speaking, that’s a an area far from where the umbilicus is. You can barely compare the two types of repairs with mesh. It’s really rare to find mesh complications for a ventral hernia repair unless you have a mesh reaction or get an infection from it, which is possible. A lot of new techniques have been going around for ventral hernias and the latest one seems to be the TEP procedure and the other being a TAPP procedure. Those aren’t new for inguinal hernia repairs but they are for ventral repairs. They seem to have advantages compared to the traditional IPOM method, which the mesh is implanted against the peritoneum, but they are still pretty new techniques without very much evidence that they are superior than an IPOM repair. If you are going to go the mesh route, try to steer away from any kind of metal fixation. There is evidence that metal fixation does cause a lot of problems, so try to find someone who will be open to using absorbable fixation.
If you plan to get pregnant again, it’s best to go with the non-mesh route because once you are pregnant with mesh, you are pretty much bound to get a recurrence and that would involve removing the mesh most likely. If you don’t plan on that AND you really want to tackle the adhesions, then go the laparoscopic route, which will address both the hernia and your adhesions.
Remember, ventral hernias are different from inguinal hernias. Mesh complications differ between the two. I’m not saying that there are no complications at all with ventral mesh repairs, there are, but like I said, you can barely compare them to the ones experienced with an inguinal hernia repair. Most post-op pain for ventral hernias is due to the type of fixation which is its best to stay away from any kind of metal and permanent fixation, especially if you are thin.
In my opinion, it’s best to go with mesh since your hernia is 3 cm. That’s considered a medium sized hernia, according to most findings. Most experts, even the ones who remove mesh, suggest that hernias over 2 cm are best repaired with mesh. But please do find a surgeon who does hernias on the daily and is up to date with what’s going on in the field. Good luck to you!
Edit: Btw, I am active as well. I run and I bike quite often and like I said the only setbacks that I’ve had in my routine was when I was fresh in the recovery phase. But you will feel some tightness for some time in the area which will eventually go away.
