Abstract

Abstract : Background: Endoscopic submucosal dissection (ESD), as a minimally invasive procedure for removal of early gastrointestinal neoplasms, is a standard approach in Asian countries. Outcomes of ESD in Western European countries significantly differ, which makes it more difficult to apply this procedure to daily-basis clinical routine. The aim of this study is to analyze the safety and efficiency of colorectal ESD based on a large series of cases performed by a single operator after finishing the learning curve period in a western referral center. Materials and Methods: We retrospectively studied 601 patients who underwent ESD procedure for colorectal neoplasm from January 2016 to December 2019 in a tertiary colorectal ESD center in Poland. Results: The overall en bloc resection was achieved in 88.02%. Complete histologic resection rate (R0) was reported at a level of 86.36%. Lesions located in the right colon were characterized by statistically lower en bloc, R0 resection, and success rate (73.95%, 71.43%, 69.75%, respectively). In 9.82% (n=59) of cases, the ESD procedure-related complications have been observed. Post-ESD bleeding occurred in 23 patients (3.83%) and perforation in 32 patients (5.32%). Twenty-seven patients were treated endoscopically (4.49%) and 5 required surgery (0.83%). Analysis of complications showed that tumors located within the right colon were characterized by the highest perforation rate at 10.92%. Within the rectum there were minimal number of perforations (2.69%), whereas the bleeding rate was 4.48%. Conclusions: Our results represent the largest material concerning ESD of colorectal lesions in the West and show that ESD is characterized by a high rate of successful resections with a low risk of complications. Thus, confirming that it is possible to obtain results similar to Asian centers and that colorectal ESD procedures can be implemented in clinical routine in western countries. Nevertheless, ESD in the right colon is still related with high rate of complications, so qualification for the ESD procedure should be very careful and discussed with the patient and should be performed by an experienced endoscopist after the learning curve.
