Mini-loop ligation of a bleeding duodenal Dieulafoy's lesion

Dieulafoy's lesion of the duodenum: a comparative review of 37 cases

Dieulafoy's lesion is an abnormally large, tortuous, submucosal vessel that erodes the overlying epithelium without primary ulceration or erosion. The lesion predominantly occurs in the proximal stomach but it is also reported in extragastric sites. The pathogenesis and precipitating factors are poorly understood. Patients frequently present with gastrointestinal haemorrhage that can range from being self-limited to massive life threatening. Although there are no standard guidelines, endoscopy has significantly impacted the diagnosis and management. This review outlines our current understanding of the epidemiology of and risk factors for Dieulafoy's lesion of the duodenum, the pathophysiology of this disorder, and currently available approaches to diagnosis and management.

Progress in treatment of bleeding in Dieulafoy's disease by endoscopic metal titanium clamp

Dieulafoy's disease is one of the rare causes of upper gastrointestinal bleeding. Since its pathogenesis is different from that of common gastrointestinal bleeding, traditional acid suppression method has a poor therapeutic effect. Over the past decade, endoscopic hemostatic technologies have developed rapidly and have been vigorously recommended as the preferred method to replace surgery. Among them, endoscopic metal clamp stops bleeding quickly, has a definite curative effect distinctly, and is increasingly advocated by clinicians. However, large-sample studies on endoscopic metal titanium clamp in the treatment of bleeding in Dieulafoy disease are still lacking. This paper systematically reviews the recent advances in the treatment of bleeding in Dieulafoy's disease by endoscopic metal titanium clamp.
