Totally endoscopic treatment of duodenal diverticulum

Intraluminal duodenal diverticulum, also called "windsock" diverticulum, is an extremely rare congenital abnormality [1]. It is mostly asymptomatic but in 10 % of cases it can cause epigastric pain, upper gastrointestinal mechanical obstruction, and, less commonly, weight loss and biliopancreatic symptoms [2]. Surgery is considered the gold standard treatment for selected symptomatic cases [3]. Endoscopic excision is not standardized in the literature and only case reports have been published [4].
