lipomas are rare gastric tumors that comprise less than 1% of gastric tumors. these tumors are usually without clinical manifestations, but sometimes they may present with severe symptoms like bleeding,intussusception, or abdominal pain. in endoscopic assessment, they manifest with subm ucosal masses with intact epithelium. endosonography and ct scan can help in diagnosis. surgical resection of...
engraftment by donor lymphocytes in an immunologically compromised host can result in donor t-cell activation against host major histocompatibility complex antigens, with resultant gvhd. the acute form of gvhd (agvhd) is characterized by erythroderma, cholestatic hepatitis, and enteritis. the intestinal symptoms of agvhd include crampy abdominal pain and watery diarrhea, often with blood. the c...
gastrointestinal stromal tumors (gist) are the most common mesenchymal tumors of the gastrointestinal tract. the biological pattern of these tumors ranges from benign-appearing small lesions to malignant sarcomas. only 3%-5% of gists are found in the duodenum. a duodenal gist is a rare source of upper gastrointestinal bleeding. a remarkable percentage of duodenal gists are localized in the thi...
Anticoagulants are frequently used medications in diverse cardiovascular diseases. Their uses highly increase the risk of bleeding from upper and lower gastrointestinal sources, whether there is a classic vitamin K antagonist or a novel oral anticoagulant. Their interruption can promote procoagulation status with different thromboembolic accidents. Discontinuation of oral anticoagulants before ...
BACKGROUND AND AIMS Data regarding the influence of dose and duration of aspirin use on risk of gastrointestinal bleeding are conflicting. METHODS We conducted a prospective cohort study of 32,989 men enrolled in the Health Professionals Follow-up Study (HPFS) in 1994 who provided biennial aspirin data. We estimated relative risk of major gastrointestinal bleeding requiring hospitalization or...
BACKGROUND AND STUDY AIMS Currently, conventional endoscopic treatments provide an unsatisfactory hemostatic outcome in upper gastrointestinal bleeding from tumor. Hemospray has been shown to be useful in many active gastrointestinal bleeding conditions. This study aimed to compare the efficacy of Hemospray and conventional endoscopic hemostasis. PATIENTS AND METHODS Fourteen patients with ac...
CONTEXT Early refeeding after nonvariceal upper gastrointestinal bleeding is safe and reduces hospital stay/costs. OBJECTIVES The aim of this study was obtaining objective data on refeeding after nonvariceal upper gastrointestinal bleeding. METHODS From 1 year span records of nonvariceal upper gastrointestinal bleeding patients that underwent urgent endoscopy: clinical features; rockall sco...
Upper and lower gastrointestinal bleeding is a medical problem that encountered in the clinic quite often. Endoscopic procedures still constitute basis of treatment bleeding. Hemoclips, argon plasma coagulation, sclerotherapy, heater probe, hemosprays accompanied by endoscopy are used alone or combination. In this study, we shared our experience using drug called Ankaferd blood stopper, which i...
Stress-related mucosal disease: incidence of bleeding and the role of omeprazole in its prophylaxis.
BACKGROUND Upper gastrointestinal bleeding is the severe complication of stress-related mucosal disease in hospitalized patients. In intensive care units (ICU), risk factors are well defined and only mechanical ventilation and coagulopathy proved to be relevant for significant bleeding. On the contrary, in non-ICU settings there is no consensus about this issue. Nevertheless, omeprazole is stil...
Gastrointestinal stromal tumours often present with insidious upper gastrointestinal symptoms. Initial definitive diagnosis can be difficult and therefore misdiagnosis is not infrequent. Here we report a case of upper GI bleeding caused by a splenic artery aneurysm that was misdiagnosed as a gastric GIST. This rare presentation of splenic artery aneurysm highlights the potential pitfalls of inv...
