Su1426 The Effectiveness of Cold Snare Polypectomy for the Removal of Small Sessile Colonic Polyps

anesthesia with an average dose of 328 29 mg. 38 patients had normal weight; 48 were overweight and 25 were obese. Analysis of variance for axial and longitudinal force parameters were not different for either BMI or procedure difficulty. Average peak push force and examination time did not differ between normal weight and obese patients at 21.6 10.0N and 25.1 13.4N, and 18.6 and 20.4 min respectively. There was no correlation between peak force and height or weight. There was no difference in longitudinal or axial force when procedures were more difficult although they took significantly longer: N 15.7min, M 18.1min and D 29.3min. Conclusion: The present study demonstrates that neither BMI, height, weight or procedure difficulty modifies the forces used to perform colonoscopy but more difficult procedures took longer. Heavier patients and more difficult exams did not require more force to perform colonoscopy. Colonoscopy force application appears to depend on the endoscopist, patient gender and anesthesia, but not on patient BMI or procedure difficulty.(Grant Support NIH/NIDDK SBIR 5R44DK068936-03)
