摘要
Due to the high risk of morbidity and mortality associated with surgical resection in this tract,endoscopic resection(ER)has taken the place of surgical resection as the first line treatment for non-ampullary duodenal adenomas.However,due to the anatomical characteristics of this area,which enhance the risk of post-ER problems,ER in the duodenum is particularly difficult.Due to a lack of data,no ER technique for superficial non-ampullary duodenal epithelial tumours(SNADETs)has yet been backed by strong,high-quality evidence;yet,traditional hot snare-based techniques are still regarded as the standard treatment.Despite having a favourable efficiency profile,adverse events during duodenal hot snare polypectomy(HSP)and hot endoscopic mucosal resection,such as delayed bleeding and perforation,have been reported to be frequent.These events are primarily caused by electrocautery-induced damage.Thus,ER techniques with a better safety profile are needed to overcome these shortcomings.Cold snare polypectomy,which has already been shown as a safer,equally effective pro-cedure compared to HSP for treatment of small colorectal polyps,is being increasingly evaluated as a potential therapeutic option for non-ampullary duodenal adenomas.The aim of this review is to report and discuss the early outcomes of the first experiences with cold snaring for SNADETs.
