Dieulafoy's Lesion in the Gaster Secondary to the Resection of Lung Cancer: A Rare Case Report Presentation

Abstract

Background: Dieulafoy’s lesion is a dilated, aberrant, submucosal vessel that erodes the overlying epithelium without obvious ulceration. Dieulafoy's lesion is a rare disease, meanwhile the lesion secondary to resection of lung cancer is even extremely rare. It is most commonly located in the lesser curvature of the stomach but rarely occurrences in extragastric sites have also been reported. To summarize the key points in the diagnosis and treatments of this disease, we present a clinical case of acute gastrointestinal bleeding due to Dieulafoy's lesion in the gaster secondary to resection of lung cancer.Case presentation: An 58-year-old woman presented with a clinical condition of haematemesis and haematochezia associated with anaemia and haemodynamic instability, needing blood transfusion. After many changes of body position, when the patient was in prone position, we finally found jet bleeding on the gastric body near the great curvature of gastric fundus under gastroscopy, and then we performed successfully with hemostatic clip placement. Hospitalization occurred without further com plications. There was no recurrence after 18 months follow-up.Conclusion: It is essential to be aware of this lesion as a possible cause of gastrointestinal bleeding and especially thoracic postoperative acute gastrointestinal appears. Timely and effective endoscopy can improve the diagnosis rate of these lesions and reduce the related mortality. At the same time, we need to pay attention to the patients with the risk factors in the perioperative period to reduce the incidence of Dieulafoy's lesion.
