Should I sue because my intestines fell out after hysterectomy?

I had a hysterectomy in the spring, no complications. At my six week checkup, my GYN said that I was healed and could resume normal activities including . A week later, after my husband and I had , my intestines came out and I had to be rushed to the hospital for emergency surgery. I was hospitalized for 5 days and now have chronic pelvic pain. Dr's commented that this is an extremely rare event but nobody will say my hysterectomy surgeon made a mistake, even though the intestine that came out looked perfect, there was no blood when it happened and there was no scars on the intestine indicating that they had been sutured in. I saw one of the top attys in our city and they said there is no proof of dr error. I have researched this and the #1 reason for this happening is poor surgical technique but there are others(http://www.greenjournal.org/cgi/content/full/103/3/572)I cant work & still recovering...help
