Abstract
Dieulafoy lesion is rarely seen, yet it can be life-threatening. This lesion makes up to 1-2% of gastrointestinal bleedings and must definitely be considered in gastrointestinal bleedings whose source cannot be identified. In this case study, the 75-year-old woman was suffering from active, fresh, and massive rectal bleeding. Colonoscopy was applied in order to find out the source of bleeding. In the typical endoscopic appearance of the lesion a single round mucosal defect in the rectum and arterial bleeding were observed. To procure hemostasis, epinephrine was injected into the lesion and the bleeding vein was sutured.
Highlights
The incidence of acute gastrointestinal bleeding is 50– 150/100000. 80% of these patients constitute the group suffering from peptic ulcer, esophageal erosion, or gastroduodenal bleeding [1]. 5% of these bleedings is occult gastrointestinal bleeding
Dieulafoy lesion is one of the causes of rarely seen occult gastrointestinal bleedings, and it can be lifethreatening as its diagnosis is difficult [2, 3]
Dieulafoy lesion is one of the well-defined causes of acute massive gastrointestinal bleedings. Even though it was defined in the beginning as the aneurysm of the gastric submucosal arteries, in the following years it was shown that this lesion can be seen in the whole gastrointestinal system
Summary
The incidence of acute gastrointestinal bleeding is 50– 150/100000. 80% of these patients constitute the group suffering from peptic ulcer, esophageal erosion, or gastroduodenal bleeding [1]. 5% of these bleedings is occult gastrointestinal bleeding. 5% of these bleedings is occult gastrointestinal bleeding. The detection of occult bleeding is difficult and endoscopic intervention and barium studies might be necessary for diagnosis. Dieulafoy lesion is one of the causes of rarely seen occult gastrointestinal bleedings, and it can be lifethreatening as its diagnosis is difficult [2, 3]. The French Surgeon George Dieulafoy identified Dieulafoy lesion in 1898 in three patients with massive upper gastrointestinal bleeding [3]. The location of Dieulafoy lesion has been identified by 71% in the stomach, 8% in the esophagus, 15% in the duodenum, 1% in the jejunum-ileum, 2% in the colon, 2% in the rectum, and 1% in the gastric anastomosis [5, 6]. Massive, and recurrent gastrointestinal bleedings are present in these patients. Bleedings can be in the form of hematemesis, melena, and fresh bleeding from the rectum
