Had colonscopy done, notes say small ac lesion near the cecum. had ct scan, waiting for results. biopsy was not done. colonscopy 2013 was clear. idea?

AC lesion: I think they meant AV (Aterio-venous) lesion which is a small vascular anomaly and most likely harmless.

Gastroenterologist: Why did you have another colonoscopy after one year? Have you had symptoms of bleeding, abdominal discomfort or anemia? Your gastroenterologist,who knows all your findings, is best qualified to advise you.

Polypoid lesion: If on colonoscopy a small lesion noted in the ascending colon not seen previously I suspect a small polypoid growth noted. If base not on a stalk, bx might have been held off for possibility that bx could lead to performation. If small such lesions hard to define on scan. Best approach is to consider repeat colonoscopy in 4-4 mo. and bx performed if lesion larger.
