A experimental trial by RL Prosst and FE Baur, Stuttgart, Germany has shown that the Traction Polypectomy Snare removes 31% more tissue than a conventional snare. Comparing the weight of colonic tissue removed with one snare deployment was 454 mg (SD 202) with the Traction Snare vs 347 mg (SD 165) with a conventional snare. This difference was statistically significant (p=0.017). 

The authors conclude that the Traction Polypectomy Snare increases the effectiveness of snare resection by avoiding the accidental loss of entrapped tissue. In addition the achievable reduction of sample numbers during piecemeal resection may increase the precision of histo-pathological assessment.
