Hi. I've had my colostomy for over 20 years (cancer). In 2007, my surgeon and I were discussing my hernia symptoms and considering moving the site of my stoma to the other side (ileostomy). We both agreed that it would be better to save what colon remains from the original surgery. So, he did a stomal revision. Unfortunately, the hernia returned so he referred me to someone that specializes in laparoscopic surgery.
He warned me that the first surgery might not be successful but there's so little involved that we decided to risk it. He was right and in fact it took two more surgeries before complete success! In on Friday am and out Saturday before noon! There are no external stitches and he uses a mesh (the trick, I think is, how to secure the mesh around the bit of colon exiting the stomach wall).
I've referred him to a friend who was very disappointed in his trip to the Shouldice Clinic and he was ecstatic with the results. I am about 6 years since my surgery with absolutely NO hernia symptoms!
His name is Dr. John Hagen with Minimally Invasive Group in Toronto. Review their site: http://www.misgroup.ca
