Two Cases of Ileal Dieulafoy Lesion with Massive Hematochezia Treated by Single Balloon Enteroscopy

Abstract

Ileal Dieulafoy lesion is an unusual vascular abnormality that can cause gastrointestinal bleeding. It can be associated with massive, life-threatening hemorrhage and requires urgent angiographic intervention or surgery. Ileal Dieulafoy lesion is hard to recognize due to inaccessibility and normal-appearing mucosa. With advances in endoscopy, aggressive diagnostic and therapeutic approaches including enteroscopy have recently been performed for small bowel bleeding. We report two cases of massive ileal Dieulafoy lesion bleeding diagnosed and treated successfully by single balloon enteroscopy with a review of the literature.

Immunohistochemical Expression of Endothelial Cell Markers in Case of Dieulafoy Lesion: Is There Is a Differences

“…Dieulafoy's lesion (DL) is a rare pathology of the gastrointestinal tract (GIT), characterized by an aberrant submucosal arterial vessel, surrounded by intact or damaged mucosa that can lead to massive bleeding and life-threatening condition (1). From the pathological point of view, the process occurs most frequently in the stomach, followed by the duodenum, colon/rectum and other parts of the GIT, while histologically it is presented as a small defect in the mucosa, surrounded by fibrinoid necrosis, on the bottom of which there is an abnormally dilated arteries 3 mm in diameter (2,3).…”

A diagnostic dilemma: a case report of concomitant duodenal Dieulafoy lesion and gastric ulcer

“…Duodenal DLs are rare, representing only 15% of reported cases [ 3 , 7 , 8 ]. Other rare sites reported include the jejunum [ 8 ], ileum [ 9 ], oesophagus [ 10 ], colon [ 11 ], and rectum [ 12 ].…”

Ileal Dieulafoy Lesion in a Patient with Glanzmann Thrombasthenia Presented with Hematochezia

“…3 There have been fewer than 20 cases reported in the literature to date. [5][6][7][8][9][10] Despite its rarity, DL should always be considered in the differential diagnosis of lower GIH. Endoscopy has advanced in recent years and endoscopic treatment is very successful in terms of achieving hemostasis.…”
