Get a second opinion.
I didn't--accepted my GI recommendation to get it done laproscopically at the big city (Pittsburgh--ShadySide) hospital by a colerectal specialist. It came apart and developed infection. I had to have emergency surgery on Sunday five days later by my surgeon's backup. It was such a mess I lost most of my colon and had to have a bag for six months. (I was in the hospital for an additonal two and half weeks after the first surgery.)
I blame the surgeon. She relocated a year later.
