background: this study aimed to compare intermittent intravenous (iv) pantoprazole and ranitidine for control of gastric acid secretion and the possible prevention of upper gastrointestinal bleeding (ugib) in critical care patients. methods: this was a randomized, double blind clinical trial study of iv pantoprazole (40 mg every12 hour) or intermittent iv ranitidine (50 mg bolus every 8 hour) i...

Duodenal gangliocytic paraganglioma (DGP) is a rare tumor that characteristically occurs in the second part of duodenum. These appear as submucosal masses that protrude into the lumen of a duodenum. Gastrointestinal bleeding is the commonest manifestation of DGP. Metastatic spread to regional lymph nodes occurs rarely. Surgical resection is the treatment of choice for DGP. A case of a DGP is re...

Dieulafoy's lesion is a relatively rare but serious cause of gastrointestinal bleeding. It usually involves the upper gastrointestinal tract. However, it has recently been reported in different regions of the gastrointestinal tract, including the rectum. Here, we report the case of a female patient who presented with fresh bleeding per rectum for 1 day with low hemoglobin level. Colonoscopy rev...

BACKGROUND The precise role of capsule endoscopy in the diagnostic algorithm of obscure gastrointestinal bleeding has yet to be determined. Despite the higher diagnostic yield of capsule endoscopy, the actual impact on clinical outcome remains poorly defined. The aim of this study was to evaluate the follow-up results of patients with obscure gastrointestinal bleeding to determine which managem...

Background and study aims Left ventricular assist devices (LVADs) are currently the standard of care in treatment of patients with end-stage heart failure waiting for heart transplant as well as destination therapy for non-transplant candidates. However, patients with LVADs are at increased risk of gastrointestinal bleeding due to the device's unique effects on hemodynamics. A major source of g...

Dieulafoy's lesions are a rare cause of gastrointestinal bleeding. This article presents the case of a young woman presenting with a massive ileal bleeding, secondary to a Dieulafoy's lesion. A computed-tomography angiography scan showed an arterial bleeding in the ileum and the diagnosis was confirmed by an emergency peroperative enteroscopy. Surgical treatment was performed. Dieulafoy's lesio...

Digestive endoscopy represents an essential diagnostic and curative tool used when presented with a suspicion of gastrointestinal (GI) bleeding. Its role is not only confined to primary detection but also to establishing the severity of a lesion and providing relevant information regarding its risk of bleeding. New endoscopic techniques, accessories and compounds make the minimally invasive tre...

BACKGROUND/AIMS This study was performed to determine whether low-dose aspirin and/or clopidogrel can induce gastrointestinal bleeding and gastroduodenal mucosal injury. METHODS A total of 387 patients who underwent coronary angiography at Seoul National University Bundang Hospital were assigned to one of three antiplatelet treatment groups: (1) control, (2) 100-mg enteric coated aspirin, and...

Duodenal metastases are a very uncommon and peculiar cause of upper gastrointestinal bleeding. However, they should be considered in a patient presenting with upper gastrointestinal bleeding and a previous history of malignancy. The importance of recognising the unusual presentation of duodenal metastasis has to be emphasised. We describe two patients with upper gastrointestinal bleeding due to...
