Clinical outcomes of Dieulafoy's lesion compared with peptic ulcer in upper gastrointestinal bleeding.

Background And Aim: Although Dieulafoy's lesion (DL) is an important cause of nonvariceal upper gastrointestinal (GI) bleeding, few studies have investigated the clinico-epidemiological outcomes due to its rarity. Here, we investigated clinical features of upper GI bleeding caused by peptic ulcer (PU) or DL and compared endoscopic treatment outcomes.

Methods: Patients with upper GI bleeding resulting from PU or DL who visited emergency room between January 2013 and December 2017 were eligible.
