Purpose: Endoscopic full-thickness resection (EFTR) is an innovative technique for the treatment of colonic lesions not feasible by conventional endoscopic resection. Here, we aimed to evaluate the efficacy and safety of a Full-Thickness Resection Device (FTRD) for colonic lesions in a high-volume tertiary referral center. Methods: A review of a prospectively collected database on patients that underwent EFTR with FTRD for colonic lesions from June 2016 to January 2021 at our institution was performed. Data regarding the clinical history, previous endoscopic treatments, pathological examination, technical and histological success, and follow-up were evaluated. Results: Thirty-five patients (26 males, median age 69 years) underwent FTRD for colonic lesion. Eighteen lesions were in the left colon, three in the transverse, and 12 in the right colon. The median size of the lesions was 13 (range 10–40) mm. Resection was technically successful in 94% of patients. The mean hospital stay was 3.2 (SD ± 1.2) days. Adverse events were reported in four cases (11.4%). Histological complete resection (R0) was achieved in 93.9% of cases. Endoscopic follow-up was available in 96.8% of patients, at a median duration of 14.6 months (3–46 months). Recurrence was observed in 19.4% of cases at a median time of 3 months (3–7 months). Five patients had multiple FTRD performed, with R0 resection in three cases. In this subset, adverse events were observed in 40% of cases. Conclusions: FTRD is safe and feasible for standard indication. The non-negligible rate of recurrence observed suggests the need for close endoscopic follow-up in these patients. Multiple EFTR could help achieve complete resection in selected cases; however, in this setting, a higher risk of adverse events was observed. [ABSTRACT FROM AUTHOR]
