When I had my first small bowel resection, I was 8 years old. The scar is over to the right side of my gut, right about where my jeans sit - lower, not 'mom jeans' and horizontal. A good two inches below my belly button, but to the side and is almost all the way over to my side, about 8 inches
When I was 16 I had my second SBR. This time my surgeon (different one from my first SBR) cut from below my belly button down to my hairline.
My SBR when I was 21 started a bit above my belly button, went around and down, over the previous incision. The next year I had another SBR (actually, it was almost a year later to the day), that one went a little further further up (22 staples). When I was 25, the incision was even a little higher (27 staples).
At 29 my gallbladder came out. Because I have so much scar tissue in there he couldn't go in there with scopes. He opened me up the hard way. This time it was horizontal, about an inch above my belly button, parallel to my first incision, this time only about 5 inches long.
Most of my horizontal scars are fairly faded. My lower one is almost 30 years old, but the upper one doesn't look much worse. It's the vertical scar that is very obvious. The lower part has been gone over 4 times and I once burnt it (big icky blister) with a heating pad.
It's not my favorite part of my body, but it is what it is and it's a battle wound that I earned through a lot of $$$ and pain. When I was 16 I hid my scars, mortified that anyone would see them. But in recent (and skinnier) years, I had no trouble wearing tops that flashed a bit of belly skin. I never have and never will have a flat stomach, but I have learned that my scars are me, show where I've been, what I've pushed through and made me tougher. They suck, but there's not much I can do about them, so I embrace them. It's also fun to screw with people (especially new doctors and nurses) by flashing my scars. They usually stop in shock.
