What type of surgery is used for twisted stomach in humans?

In my case the secum had wrapped itself around my large intestine, cutting off all circulation. So basically they made an incision from my navel to just above the pubic area. Opened me up untwisted my secum and sewed it to the stomach wall and stapled me up. They took out my appendices while they were there as well. I was in the hospital for thirteen days. The pain when it happened is UNREAL! No one could understand why it took me 20hrs to seek medical attention. The truth is I wasn't aware of time...passed out from the pain.
