Gastric lipoma is a rare tumor that constitutes approximately 3% of all benign tumors of the stomach and mainly is seen as a submucosal mass.

Extrahepatic portal venous obstruction, although rare in the western world, is a common cause of major and life threatening upper gastrointestinal bleeding among the poor in developing countries. Patients have large spleens and stunted growth. The diagnosis is easily confirmed by Doppler ultrasonography. Endoscopy sclerotherapy is the best option for the control of acute variceal bleeding.

Various complications of hydatid cyst have been recognized to date. We have encountered one such complication-rupture of hydatid cyst to the duodenum­ leading to upper gastrointestinal bleeding in a 40 year old male, who referred with severe right upper quadrant (RUQ) pain and gastrointestinal bleeding of a few hours' duration. Laparotomy revealed a cyst (7 x 15 cm) in the left lobe of the ...

To evaluate the GB prophylaxis in Intensive Care Units (ICU), and to compare with the guidelines. METHODS We carried out a cross-sectional multicenter study in 21 medical-surgical ICU in Brazil to investigate this issue. For dat...

AIMS The risk of gastrointestinal (GI) bleeding limits the use of antiplatelet and anticoagulant drugs. Risk factors for GI bleeding in post- myocardial infarction (MI) patients have not been well defined. We sought to identify risk factors for GI bleeding in patients following MI. METHODS AND RESULTS The VALsartan In Acute myocardial iNfarcTion trial (VALIANT) enrolled 14 703 post-MI patient...

Exsanguinating hemorrhage often results from a duodenal ulcer penetrating the posterior wall. If the patient's condition does not stabilize after replacement of 25 percent of the blood volume, surgery must be undertaken immediately.

Lower GI bleeding (LGIB) afflicts 20 to 27 of every 100,000 persons annually in the United States. The rate of LGIB increases more than 200-fold from the third to the ninth decade of life, with 25% to 35% of all cases occurring in elderly patients. It is one of the common medical emergencies that can become life-threatening in elderly patients. Risk stratification for LGIB by Strate et al. has ...
