When polyps are found during colonoscopy that are 2-3 CM in size why would a doctor leave them instead of taking a biopsy?

When polyps are found during colonoscopy that are 2-3 CM in size why would a doctor leave them instead of taking a biopsy?

Colonoscopy: Biopsies are usually only taken of any polyps that dont look normal. Polyps of that tiny size are unlikely to be a problem and to a trained eye, the risk of taking the biopsy probably higher than the risk of possible malignancy! I am sure you were told to have a follow up colonoscopy in 6 mos to 1 year. ...Read more

Do GI doctors perform anoscopes and rectoscopes during a colonoscopy? Can it be requested or are anoscope/rectoscope exclusive to proctologists?

Included: A colonoscope is inserted into the anus, ascends through the rectum, and goes on to check the rest of the bowel. Thus colonoscopy includes examination of the anus and rectum. However, if there is a suspicion of anal pre-cancer (e.g. In HIV positive men) a specialized magnifying instrument is used to assess the anus. ...Read more

Is it possible for doctors to discover blocked heart arteries during a colonoscopy?

Is it possible for doctors to discover blocked heart arteries during a colonoscopy?

Not directly: The colonoscopy does not in any way look at the heart, only at the lining of your colon. If a patient has issues during the test such as chest pain, irregular heart beat or hypotension, coronary artery disease may be considered, but different types of testing will be needed to verify. ...Read more

Should i be worried about inflammation found inside my colon during colonoscopy? What can cause it? Doc said the biopsy came back normal?

Not now/depends,,,: At this point, unless you've got any positive signs of an inflammatory bowel condition, you should not worry excessively. Your biopsy was negative. Your mother having colon cancer should motivate you to take steps to take care of your health that way with a high fiber diet and check-ups like the colonoscopy that you did. Close follow up with your doctor also helps a lot. ...Read more

During a colonoscopy a few weeks ago i remember my upper body being moved and/or shaken a bit by the nurse and doctor. Any reason for that?

Repositioning: Sometimes during a colonoscopy it is necessary to reposition you. This may allow for easier passage of the scope. It may also be done for other issues, like to improve your breathing or put you in a more comfortable position if you moved. Most colonoscopies are done under sedation and you are not entirely unconscious. You may remember parts of what happens but not the entire context. ...Read more

Doctor said that if i was preforated during colonoscopy i would know by know..Its been 13 days..Is this true?Sorry I have really bad health anxiety

Most likely: If you have a significant perforation in your colon, that will spill your colon contents "usually stool" into the surrounding cavity which is called peritoneum, that usually triggers severe inflammatory response that might bring down your whole body, i tend to agree with your doctor that if you perforated your colon you'd have been in the hospital by now feeling really sick, .... ...Read more

I have external Hemorrhoids I went to a doctor and they set me up for a colonoscopy. Is it possible they can remove the hemorrhoids during colonoscopy?

Why colonoscopy???: You stated age is 27 years! Is it that you have a fat wallet that they want to trim down? If they tell you that you had some rectal bleeding, remind them that you have hemorrhoids and you would like to have them removed first. Do you have a family history of ulcerative colitis or Crohn's disease? Demand an explanation for doing that procedure on you and get second opinion! ...Read more
