Dieulafoy's lesion in the cecum: A rare case report presentation

Dieulafoy's lesion is a rare entity, normally present in the stomach and more rarely in the colon, and it is responsible for 1% to 5% of acute gastrointestinal bleeding cases. Its true incidence may be underrated, since most cases are asymptomatic and difficult to diagnose despite endoscopic advances. We present a clinical case of acute gastrointestinal bleeding due to Dieulafoy's lesion in the cecum.

An 85-year-old woman presented with a clinical condition of haematochezia associated with anaemia and haemodynamic instability, needing blood transfusion. Colonoscopy demonstrated a Dieulafoy's lesion in the cecum with active bleeding, and haemostasis was performed successfully with localized adrenaline injection and haemostatic clip placement. Hospitalization occurred without further complications.

The diagnosis of Dieulafoy's lesion is difficult because it is a rare condition and thus, usually not included in the differential diagnosis of gastrointestinal bleeding. Its endoscopic diagnostic and therapeutic approach is the standard method in the event of an acute gastrointestinal bleeding episode, with greater efficiency with the combined use of haemostatic techniques. Surgery is necessary in less than 5% of cases when bleeding is not effectively controlled by endoscopic or angiographic techniques.

It is essential to be aware of this lesion as a possible cause of gastrointestinal bleeding and differentiate it from other causes. Advances in endoscopy have increased the rate of diagnosis of these lesions and reduced their associated mortality.
