1. Surgery Overview
Colonoscopy is a diagnostic procedure used to examine the inner lining of the large intestine (colon and rectum). A long, flexible tube with a camera (colonoscope) is inserted through the rectum to detect abnormalities such as polyps, inflammation, bleeding, or signs of colorectal cancer. It can also be used to take biopsies or remove polyps during the same procedure.
2. Type of Anesthesia
Colonoscopy is usually performed under mild to moderate sedation, which helps the patient relax and remain comfortable during the procedure. In some cases, deeper sedation or general anesthesia may be used based on the patient’s condition and preference.
3. Possible Risks and Complications
Bloating or cramping
Bleeding (especially after a biopsy or polyp removal)
Perforation (a rare tear in the colon wall)
Reaction to sedatives or anesthesia
Infection (rare)
Incomplete examination if bowel preparation was insufficient
4. Hospital Stay Duration
Colonoscopy is typically an outpatient procedure.
Patients are monitored for a short time after the procedure and can usually go home the same day.
5. Important Post-Operative Care
Rest for the remainder of the day after the procedure; do not drive or operate machinery for 24 hours if sedation was used
Resume a normal diet unless instructed otherwise by the doctor
Monitor for signs of complications such as severe abdominal pain, heavy rectal bleeding, or fever, and seek medical attention if they occur
Drink plenty of fluids to rehydrate after bowel preparation
Follow your doctor’s recommendations for follow-up, especially if polyps were removed or biopsies taken.
