Abstract

Background and Aims: Endoscopic mucosal resection (EMR) has become the standard for removing large colon polyps but has a 10%-30% recurrence rate using standard techniques. Data shows improved recurrence rates with focal therapy of the edge of the resection base using cautery. We examine a novel technique, hybrid APC assisted EMR, which treats both the edge and the base with cautery to assess its effect on local recurrence. Methods: We reviewed all EMRs of polyps >2 cm by a single endoscopist with 6-month follow-up from May 2018 to November 2019 using both standard EMR as well as hybrid APC assisted EMR to assess local recurrence as well adverse events. Results: Forty-eight patients with 59 polyps removed by EMR had full 6 month follow up with a mean age of 66.1 years of age, 45% were female. Thirty polyps were removed by hybrid APC assisted EMR and 29 removed with standard EMR. Overall, 0 (0%) polyps in the h-APC arm had local recurrence while 6 (20.7%) in the standard group had histological proven local recurrence (P = 0.01). Postresection bleeding occurred in 6 patients, 2 in the hAPC arm and 4 in the standard arm (P = 0.41). Conclusion: In this retrospective pilot study, hybrid APC assisted EMR was superior to conventional EMR for local recurrence after removal of large colon polyps and trended towards a less post-EMR bleeds.
