Scarring would depend on weather you had a "traditional" surgery with an incision or if you had laparoscopic surgery. I had my colon removed via an incision from the base of my diaphragm to just below my belly button and so I have a 9" scar. Being a male it really does not bother me that much. With the laparoscopic surgery there are 3 small incisions made for the instruments and from what I read the scars are minimal. I'm sure someone on this forum can tewll you first hand.
Good Luck!!
