Clinical and financial impacts of introducing an endoscopic mucosal resection service for treatment of patients with large colonic polyps into a regional tertiary hospital.

Abstract

Background and study aims Endoscopic mucosal resection (EMR) of large sessile or laterally spreading colonic lesions is a safe alternative to surgery. We assessed reductions in Surgical Resection (SR) rates and associated clinical and financial benefits following the introduction of an EMR service to a large regional center. Patients and methods Ongoing prospective intention-to-treat analysis of EMR was undertaken from time of service inception in 2009 to 2017. Retrospective data for SR of large sessile/laterally spreading colonic lesions were collected for the period 4 years before commencement of the EMR service (2005-2008) and 9 years after its introduction (2009-2017). Results From 2005 to 2008, 32 surgical procedures were performed for non-malignant colonic neoplasia (50% male, median age 68 years, median Length of Stay (LoS) 10 days). Following the introduction of the EMR service, there was a 56% reduction in the number of patients referred for surgery (32 surgical procedures, 47% male, median age 70 years, median LoS 8.5 days). During this period, EMR was successfully performed in 183 patients with 216 lesions resected (60% male, median age 68 years, median LoS 1 day). Compared to the SR group, the EMR cohort had a lower peri-procedural complication rate (7.7% vs 54.7%, P <0.0001), and shorter average LoS (1 vs 9 days, P <0.0001). A cost saving of AUD$19543.5 was seen per lesion removed with EMR compared to SR. Conclusions The introduction of a dedicated EMR service into a large regional center as an alternative to SR can lead to a substantial decrease in unnecessary surgery with subsequent clinical and financial benefits.Copyright © 2019 Georg Thieme Verlag.
