Abstract

Exposed endoscopic full-thickness resection (EFTR), with or without laparoscopic assistance, is an emergent natural orifice transluminal endoscopic surgery technique with promising safety and efficacy for the management of gastrointestinal submucosal tumors (SMTs) arising from the muscularis propria (MP), especially of the gastric wall. To date, evidence concerning duodenal exposed EFTR is lacking, mainly due to both the technical difficulty involved because of the special duodenal anatomy and concerns about safety and effectiveness of transmural wall defect closure. However, given the non-negligible morbidity and mortality associated with duodenal surgery, the recent availability of dedicated endoscopic tools for tissue-approximation capable to realize full-thickness defect closure could help in promoting the adoption of this endosurgical technique among referral centers. The aim of our study was to review the current evidence concerning exposed EFTR with or without laparoscopic assistance for the treatment of MP-arising duodenal SMTs.

Core Tip: Exposed endoscopic full-thickness resection (EFTR) is a promising minimally invasive alternative to surgery for the removal of gastrointestinal submucosal tumors (SMTs) originating from the muscularis propria. To date, evidence concerning duodenal exposed EFTR is lacking, mainly due to both the technical difficulty and concerns about an effective closure of the transmural defect. However, given the non-negligible morbidity and mortality associated with duodenal surgery, the recent availability of dedicated endoscopic devices able to achieve a full-thickness defect closure could help in overcoming these concerns. Our study aimed to review the current evidence regarding exposed EFTR for deep duodenal SMTs.
