Home > Sigmoidoscopy with Polypectomy

Overview

Sigmoidoscopy with polypectomy is a diagnostic and therapeutic procedure used to examine the lower part of the large intestine (the sigmoid colon and rectum) and remove any abnormal growths (polyps) found during the test. It helps in early detection and prevention of colorectal cancer and is a safe, minimally invasive outpatient procedure.

What is a sigmoidoscopy with polypectomy?

It is a procedure where a flexible tube with a camera (sigmoidoscope) is inserted through the rectum to examine the lower colon. If polyps (small growths) are found, they can be removed during the same procedure using special instruments — this process is called a polypectomy.

Why is a sigmoidoscopy with polypectomy done?

It is recommended for:

  • Screening or prevention of colorectal cancer
  • Investigating symptoms such as bleeding, pain, or changes in bowel habits
  • Removing detected polyps to prevent them from becoming cancerous
How do I prepare for the procedure?

Preparation involves:

  • A clear liquid diet for 12–24 hours before the procedure
  • Laxatives or enemas to clean the colon
  • Avoiding solid food on the day of the test
  • Your doctor will give specific instructions for preparation.
Is the procedure safe?

Yes. It is a safe and commonly performed test. Minor risks like bloating, bleeding (after polyp removal), or cramping can occur but resolve quickly. Serious complications are extremely rare.

What happens if polyps are found during sigmoidoscopy?

Polyps are immediately removed using a snare or forceps during the same session and sent for biopsy (microscopic examination) to check if they are benign or precancerous.

What is recovery like after sigmoidoscopy with polypectomy?
  • Most patients can go home within an hour after the procedure
  • Mild gas or bloating is common and temporary
  • Resume normal diet and activities the next day
  • Avoid heavy lifting or strenuous activity for 24 hours if a polyp was removed
How often should I get a sigmoidoscopy?

If polyps are found, follow-up depends on the biopsy results. Generally, doctors recommend repeat screening every 3–5 years, or sooner if advised.
