Endoscopic treatment of duodenal varices with cyanoacrylate.

Background: the duodenum is the most common location for ectopic varices. Bleeding is rare, but when it appears, it is massive and difficult to control.

Material And Methods: retrospective description of five clinical cases of digestive bleeding secondary to duodenal varices that we observed between the years 2011 and 2012, together with their clinical characteristics, endoscopic diagnosis, endoscopic treatment with cyanoacrylate injection and the posterior follow-up and assessment of new bleeding.

Prognostic factors for recurrence of gastrointestinal bleeding due to Dieulafoy's lesion.

Aim: To analyze the effectiveness of the endoscopic therapy and to identify prognostic factors for recurrent bleeding.

Methods: Retrospective study of patients with gastrointestinal bleeding secondary to Dieulafoy's lesion (DL) from 2005 to 2011. We analyzed the demographic characteristics of the patients, risk factors for gastrointestinal bleeding, endoscopic findings, characteristics of the endoscopic treatment, and the recurrence of bleeding.
