Endoscopic removal of abnormal growths (polyps) from the GI tract lining, most often during a colonoscopy or upper-GI endoscopy.

Why you need it
• Prevent progression of adenomatous polyps to cancer
• Treat bleeding or obstruction caused by polyps

Preparation
• Bowel prep for colon polypectomy; fasting 6 hours for upper-GI
• Discuss blood-thinner management with your doctor
• Arrange transport after sedation

During the procedure
• Snare or forceps used to remove the polyp; electrocautery seals the base
• Biopsy or retrieval of tissue for pathology
• Duration: 10–30 minutes depending on number and size of polyps

Afterwards
• Recovery for 30–60 minutes
• Clear liquids first, then light diet
• Avoid heavy lifting for 24 hours

Risks & complications
• Bleeding (1–2%)
• Post-polypectomy syndrome (fever, pain without perforation) ~1%
• Perforation (<0.1%)

Follow-up
• Pathology in 3–5 days
• Repeat colonoscopy recommended based on polyp characteristics
