Therapeutic Colonoscopy/Polyp Removal
During the colonoscopy, polyps, benign tumors which may have the potential to become malignant, may be found. Sometimes, a thin wire snare is used to lasso the polyp and electrocautery (electrical heat) is applied to painlessly remove it. If a tissue sample (biopsy) was collected during the procedure, it will be sent to the lab where it is examined for evidence of certain diseases. While your doctor may be able to discuss some of the findings with you immediately following the procedure, most results are usually available within one week.
Additionally this procedure can control the bleeding caused by diverticulae, angiodysplasias (abnormal friable blood vessels of the lining of the colon) and ulcers. The risks of colonoscopy include gastrointestinal bleeding and perforation.
