AI Article Synopsis

  • A 60-year-old patient with cirrhosis from alcohol use is hospitalized due to stone cholangitis and undergoes an endoscopic procedure that leads to severe upper digestive bleeding.
  • The patient's condition worsens with signs of bacteremia, raising concerns about potential endocarditis, prompting a PET-CT scan for further evaluation.
  • After undergoing the PET-CT, the patient experiences rectal bleeding; during some PET-CT preparations, heparin is used to enhance imaging quality.

Article Abstract

A 60-year-old patient, known for cirrhosis of alcoholic origin with several hemorrhagic risk factors, is hospitalized for stone cholangitis. He benefits from endoscopic retrograde cholangiopancreatography which is complicated by several upper digestive hemorrhages due to bleeding from the duodenal papilla. The hospital stay is compounded by bacteremia, suspicious for endocarditis, prompting the performance of a PET-CT. Just after this medical examination, the patient again presents with rectal bleeding. In certain 18F-FDG PET-CT preparation protocols, the administration of heparin is carried out in order to improve the quality of the images.

Background: The management of thromboembolic risk and the necessity for timely hemorrhage control make anticoagulant-related gastrointestinal (GI) bleeding clinically challenging.

Objective: This study aimed to evaluate clinical outcomes (such as bleeding control and mortality) and the effectiveness of anticoagulation reversal techniques in patients with anticoagulant-related GI bleeding in emergency settings.

Methodology: This prospective, observational study conducted at Lady Reading Hospital, Peshawar, from January to December 2023, included patients aged 18 or older with GI bleeding on warfarin or direct oral anticoagulants (DOACs).

Introduction And Importance: Dieulafoy's lesion is a rare but serious cause of gastrointestinal bleeding, typically affecting older adults. It involves an aberrant arteriole eroding the gastric mucosa, resulting in severe, recurrent bleeding that poses diagnostic and management challenges. We present a case report of massive gastrointestinal hemorrhage with hemodynamic instability associated with a Dieulafoy's lesion.
