Abstract
Background Endoscopic full-thickness resection (EFTR) significantly expands the spectrum of endoscopic colorectal resection methods for lesions that show no lifting sign, submucosal lesions and mucosal carcinomas. The aim of our study was to evaluate the efficacy and safety of EFTR using a commercially available full thickness resection device (FTRD) by assessing the completeness of the full-thickness resection, the technical success, as well as complications in a cohort of patients from three referral centers in Germany. Another aim was to determine which patient subpopulations benefit most in clinical practice. Methods This retrospective multicenter study was conducted on consecutive patients who were admitted to three referral centers in Germany between November 2014 and December 2017. The EFTR was conducted according to the standard indications using the FTRD System (OVESCO, Tubingen, Germany). Data were obtained from prospectively maintained institutional databases. Results There were 70 patients, 42 males and 25 females with a mean age of 79.5 years (range 25-89 years) who had colonoscopy for EFTR. In three patients EFTR was not feasible because the lesions were too large. Of the remaining 67 patients, 52 had recurrent adenomas, 10 had high-grade intraepithelial neoplasia or mucosal carcinoma and five had a subepithelial lesion. Resection was technically successful in 65 patients (97.0%). Histologically complete resection (R0) was achieved in 59/65 patients (90.8%). The R0 resection rate was lower for lesions > 20 mm (86.5%) versus lesions <= 20 mm (92.9%). The total complication rate was 14.9%: there was one major complication (perforation of sigmoid colon), while all other complications were minor. Conclusions EFTR yields excellent resection rates for benign recurrent adenomas with non-lifting sign, advanced histopathological findings or submucosal lesions when the procedure is performed in experienced hands and for the correct indication. Thus, surgery can be avoided in many cases. For all lesions the risk of R1 resection goes up with the size of the lesion and careful patient selection is mandatory.
