A colon surgeon or colorectal surgeon is a surgeon who is board certified in general surgery and then completes a one year fellowship program in colon and rectal surgery.
During that fellowship the fellow gains intensive training in treating patients with colon and rectal cancer, diverticulitis, Crohn’s disease, ulcerative colitis and complex anorectal diseases. The fellow also gains training in laparoscopic colon surgery and complex operations including sphincter preservation surgery for rectal cancer (proctectomy with Coloanal J pouch), ileoanal J pouch for ulcerative colitis and strictureplasty for small bowel preservation in Crohn's disease. After the fellowship is completed there are two examinations required for Board Certification. Choosing a board certified colon surgeon to treat your colorectal disease means you have chosen a surgeon who has received advanced surgical training and deemed an expert in this highly specialized field, colorectal surgery.
