In the majority of cases, polyps are removed at the time of colonoscopy without requiring a repeat procedure. In some exceptional cases (less than 10 percent) where the polyps are large or in a position that is difficult to access a repeat procedure is arranged with appropriate accessories to remove the polyps.
Dr Pawan Lekharaju is experienced in all standard and advanced techniques to remove the polyps at the time of colonoscopy including cold snare polypectomy, hot snare polypectomy and EMR (endoscopic mucosal resection). All polyps removed will be sent for histological analysis to confirm the nature of the polyp and appropriate surveillance will be arranged accordingly.
What's involved
The procedure
- polypectomy performed during colonoscopy - usually in the same session.
- technique selected based on polyp size, morphology and access: cold snare polypectomy, hot snare polypectomy and EMR.
- All polyps retrieved are sent to the lab for histological analysis to determine appropriate surveillance
Afterwards
Recovery & follow-up
- Mild bloating and discomfort will occu for few hours to days, this typically resolves the same day.
- Avoid air travel for 14 days after colonoscopy and polyp removal
- instructions regarding how to stop and restart your blood thinners prior to and post colonoscopy will be explained during the clinic visit
- Histology results reviewed at a follow-up appointment within 2–3 weeks
- Personalised surveillance colonoscopy interval agreed based on polyp type, size, and number
- Surveillance colonoscopy will be organised according to the biopsy results
FAQs
Frequently Asked Questions
Are all polyps cancerous?
no – most colonic polyps are non cancerous. However, there are certain type of polyps that if left untreated may develop into cancers overtime. Removing them minimises the risk of developing cancer.
Will I need surgery?
In the vast majority of cases, no. Polypectomy is performed endoscopically during your colonoscopy, with no incisions required. Surgical referral is only considered for very large or complex lesions.
How long does polypectomy take?
It is performed within the colonoscopy itself — typically adding only a few minutes to the total procedure time. You are unlikely to notice any difference during the examination.
When will I get the biopsy results?
Histological results are typically available within 7–10 working days. Dr Lekharaju will review these with you at a follow-up appointment and agree an appropriate surveillance plan.
How soon can I return to normal activity?
Most patients return to normal activity within 24 hours. Dr Lekharaju will advise on any specific restrictions based on the size and location of polyps removed.
