How long does colonoscopy take to work for bowel polyps?

A flexible camera lets the clinician inspect the lining of the rectum and colon in real time. A small polyp may be snared or sampled during the same procedure. That action deals with the visible polyp, but it does not provide an instant laboratory diagnosis. Tissue is examined after the procedure, and the result helps show whether the growth is benign, precancerous, or cancerous. The endoscopist may explain what was seen before you leave, although the final pathology report follows later.

Follow the bowel-preparation instructions carefully because stool can hide small growths. Arrange an escort if sedation is planned, and do not drive until your care team says it is safe. Afterward, mild bloating or cramping can occur. Follow the discharge advice, including when to resume food, medicines, and usual activity. Keep the appointment where results and the next surveillance plan will be discussed.

Contact the endoscopy team urgently for severe or worsening abdominal pain, repeated vomiting, fever, heavy rectal bleeding, faintness, or breathing difficulty after sedation. A small amount of bleeding can occur after a polyp is removed, but the discharge instructions should explain what your service considers concerning.

Ask whether a polyp was found or removed, when the pathology report is expected, and how the findings affect your next colonoscopy. Ask which symptoms should prompt a call after the procedure and whether any medicines need temporary adjustment.
