Arterioenteric fistula is a rare cause of lower gastrointestinal bleeding, yet it can potentially cause massive, life-threatening bleeding. Patients with an advanced pelvic malignancy can develop hemorrhage from an arterioenteric fistula. Selective mesenteric angiography is unable to demonstrate the source of bleeding in these patients, so evaluation of the iliac arteries is essential. We prese...

BACKGROUND Nonvariceal upper gastrointestinal bleeding emerges as a major complication of using antiplatelet agents and/or anticoagulants and represents a clinical challenge in patients undergoing these therapies.

HYPOTHESIS Cinematic technetium Tc 99m red blood cell ((99m)Tc-RBC) scans, in which real-time scanning is performed and analyzed, can accurately localize gastrointestinal bleeding and thus direct selective surgical intervention. DESIGN Retrospective medical record review with historical controls. SETTING Large, university-affiliated public hospital in urban setting. PATIENTS Twenty-six pa...

Obscure gastrointestinal bleeding constitutes approximately fi ve percent of all gastrointestinal bleeding cases. Patients with this condition are often diffi cult to diagnose and frequently undergo extensive GI testing. This is no news item to all gastrointestinal specialists. The following cases highlight several different presentation scenarios, the long road to correct diagnosis, and some i...

Gastrointestinal bleedings are relevant side effects in patients during anticoagulant therapy for atrial fibrillation. Direct oral anticoagulants (DOACs) less correlated with major bleeding events than vitamin K antagonists (VKAs), but concerns present about the relative risk of gastrointestinal bleeding. Here we report case a patient fibrillation and dementia on DOAC treatment who developed SS...

OBJECTIVE To evaluate gastrointestinal and cardiovascular adverse event risks associated with optical colonoscopy (OC) among Medicare outpatients who received computed tomography colonography (CTC) as their initial method of colorectal evaluation. METHODS Medicare claims were compared between 6,114 outpatients ≥ 66 years who received initial CTC and 149,202 outpatients who received initial OC...

In patients with acute pancreatitis, profuse gastrointestinal bleeding is associated with a high death rate. The cause of such bleeding must be evaluated and the bleeding controlled urgently. Aneurysm formation is usually the cause of the bleeding. Angiography is needed to make a definitive diagnosis and the bleeding site should be controlled by angiographic embolization if possible. If this fa...

We report a case of recurrent severe upper gastrointestinal bleeding where the bleeding source was difficult to find during recurrent hospitalizations. Eventually videocapsule endoscopy was the modality that finally diagnosed an ulcerated lipoma within an area of intussuscepted jejunum. Segmental resection of small bowel was performed and no further bleeding episodes have occurred. Our case ill...
