I am 58 years old male. I have Lynch Syndrome and have had two colon cancers in the past. My last colon cancer was 10 years ago and I underwent three surgeries (segmental colectomy) and two rounds of chemotherapy. I have gone the past ten years with no trouble, but recently, my doctor found two polyps near the splenic flexure of my colon. Because of their large size (>2cm), he was not able to remove them during the colonoscopy. The biopsy indicates that both polyps are precancerous--specifically, tubular adenomas with high grade dysplasia. I have been getting annual colonoscopies for 10 years. The fast development of the polyps within one year made my GI doctor quite uneasy. Since I have Lynch Syndrome, he suggested that I get a radical surgery where only 3cm of my rectum is left and I need a J-pouch (to act as a reservoir for stool). This procedure will require three surgeries. I understand that Lynch Syndrome may increase my chance of getting rectal cancer, but my prior cancers and polyps were all far away from rectum. I am leaning towards either an ileorectal anastomosis or an ileosigmoid anastomosis without a J-pouch. Basically, I am leaning towards just getting one surgery instead of three where a J-pouch is created.
I know the decision is based on two factors: 1) getting another cancer in the future and 2) having a relatively good quality of life. I am wondering if some of you have also faced this dilemma. If yes, would you please share your experience?
