[Dieulafoy's lesion].

Area of Science:

• Gastroenterology
• Surgical Pathology

Background:

• Dieulafoy's lesion, a rare cause of massive upper gastrointestinal bleeding, involves an abnormal submucosal artery.
• First described in 1884, its characteristics were detailed by surgeon Dieulafoy 24 years later.

Observation:

• The lesion typically presents as a protruding, tortuous artery within normal gastric mucosa, often on the posterior wall near the cardia.
• Preoperative diagnosis is challenging, leading to frequent misdiagnosis and overlooked lesions during surgery.

Findings:

• A case report details a 30-year-old patient undergoing surgery for upper gastrointestinal bleeding due to this condition.
• Surgical intervention, including wedge resection or oversewing, remains the primary treatment modality.

Implications:

• Delayed diagnosis and treatment of Dieulafoy's lesion can result in recurrent bleeding and necessitate repeat surgeries.
• Improved diagnostic techniques and surgical approaches are crucial for managing this rare but potentially life-threatening condition.
