Polypectomy Complication Risk by Size Calculator

Estimate post-polypectomy bleeding and perforation risk based on polyp size, location, morphology, and technique. Large sessile polyps (>20mm) have 1–5% complication rate. Piecemeal EMR up to 8%.

Clinical Guidance

BMI is a screening measure of body size, not a direct measure of body fat. The standard WHO categories are underweight (<18.5), normal (18.5–24.9), overweight (25–29.9), and obese (≥30).

BMI can overestimate body fat in athletes with high muscle mass and underestimate it in older adults with low muscle mass. Interpret it alongside waist circumference and clinical context rather than as a standalone diagnosis.

How It Works

Estimate post-polypectomy bleeding and perforation risk based on polyp size, location, morphology, and technique. Large sessile polyps (>20mm) have 1–5% complication rate. Piecemeal EMR up to 8%

Each component has a specific meaning:

  • Polyp size — The polyp size recorded for the scenario being assessed.
  • Location — The location recorded for the scenario being assessed.
  • Morphology — The morphology recorded for the scenario being assessed.
  • Technique — The technique recorded for the scenario being assessed.

Note: Interpret the polypectomy risk result against the thresholds and context described above.

How to Use

Enter the polyp size, location, morphology, technique for the scenario you are assessing. Estimate post-polypectomy bleeding and perforation risk based on polyp size, location, morphology, and technique. Large sessile polyps (>20mm) have 1–5% complication rate. Piecemeal EMR up to 8%. Use the polypectomy risk result to inform your calculation.
