Dear Tharu, I wouldnt say that your condition is related to appendix
removal. It could be complication of it but not so many years after the procedure. If the surgery was performed correctly then i dont see a reason for your symptoms except abdominal adhesions
but I doubt it. So i suggest complete gastroenteral evaluation including colonoscopy
markers and red blood count. Most common causes of blood in the stool are benign (hemorrhoids, fissures and angiodysplasie, polyps) but some more serious disorders like tumors and ulcerative colitis
sholud be ruled out. If you insist you can tell your doctor to do CT abdominal scan to look for appendikx base and find any sign og abscesses formation or adhesions. You sholud also try to find dietary suggestions for opstipation and avoid food that irritates opstipation and eat lot of vegetables, fruit and drink enough water.
Wish you good health, Dr. Ivan Romic, Rominho
