Colonoscopy
Protecting Your Digestive Health Through Colon Cancer Screening
Are you age 45 or older, experiencing rectal bleeding, or due for a follow-up examination? A colonoscopy allows Dr. Tieng to examine the entire colon, identify abnormalities, remove precancerous polyps, and evaluate digestive symptoms.
A colonoscopy may be recommended to:
- Screen for colorectal cancer
- Remove precancerous polyps
- Evaluate blood in the stool or unexplained anemia
- Investigate persistent changes in bowel habits
- Assess ongoing abdominal pain or diarrhea
- Monitor inflammatory bowel disease
- Follow up on previous polyps or abnormal test results
A thin, flexible camera is carefully guided through the colon while you are comfortably sedated. Dr. Tieng examines the lining of the colon and can remove polyps or collect small tissue samples when necessary.
Most patients receive sedation to help them remain comfortable during the procedure. The anesthesia team will review the sedation plan and answer any questions before the colonoscopy begins.
Yes. Because sedation can affect alertness and coordination, you will need a responsible adult to drive you home. You should not drive, return to work, or make important decisions for the remainder of the day.
The colonoscopy itself often takes less than an hour, but you should generally plan to spend approximately two to three hours at the facility for check-in, preparation, the procedure, and recovery. Timing may vary.
Dr. Tieng performs colonoscopies at affiliated outpatient surgery centers. The office will confirm the exact facility, arrival time, and check-in instructions when your procedure is scheduled.
Dr. Tieng will usually discuss the initial findings with you or your designated family member after the procedure. Laboratory results from polyps or tissue samples may take several days, and the office will explain how you will receive the final results.
Most patients return home the same day. Temporary bloating, gas, or mild cramping can occur and usually improves quickly. You will receive written recovery instructions, including symptoms that should prompt a call to the office or urgent medical care.
A successful colonoscopy depends on a clean colon.
You will receive detailed preparation instructions before your colonoscopy. These instructions explain when to begin a clear-liquid diet, how and when to take the bowel-preparation solution, which medications may need to be adjusted, and when to stop eating or drinking before the procedure.
Following the instructions carefully is essential because an inadequately cleaned colon can make it harder to detect polyps or other abnormalities and may require the procedure to be rescheduled.
