Gastric varices are dilated submucosal veins in the lining of the stomach, which can be a life-threatening cause of bleeding in the upper gastrointestinal tract.They are most commonly found in patients with portal hypertension, or elevated pressure in the portal vein system, which may be a complication of cirrhosis.
Gastric antral vascular ectasia (GAVE) is an uncommon cause of chronic gastrointestinal bleeding or iron deficiency anemia. [1] [2] The condition is associated with dilated small blood vessels in the gastric antrum, which is a distal part of the stomach. [1] The dilated vessels result in intestinal bleeding. [3]
Patients with portal hypertensive gastropathy may experience bleeding from the stomach, which may uncommonly manifest itself in vomiting blood or melena; however, portal hypertension may cause several other more common sources of upper gastrointestinal bleeding, such as esophageal varices and gastric varices. On endoscopic evaluation of the ...
This is in addition to endoscopic banding or sclerotherapy for the varices. [13] If this is sufficient then beta blockers and nitrates may be used for the prevention of re-bleeding. [13] If bleeding continues, balloon tamponade with a Sengstaken-Blakemore tube or Minnesota tube may be used in an attempt to mechanically compress the varices. [13]
Holman used simulated gastric specimens and found the Hemoccult test to have significant problems with non-specificity and false-positive results, whereas the Gastroccult test was very accurate. [12] Holman found that by 120 seconds after the developer was applied, the Hemoccult test was positive on all control samples.
Barium X-ray examinations are useful tools for the study of appearance and function of the parts of the gastrointestinal tract. They are used to diagnose and monitor esophageal reflux, dysphagia, hiatus hernia, strictures, diverticula, pyloric stenosis, gastritis, enteritis, volvulus, varices, ulcers, tumors, and gastrointestinal dysmotility, as well as to detect foreign bodies.
A varix (pl.: varices) is an abnormally dilated blood vessel with a tortuous course. Varices usually occur in the venous system, but may also occur in arterial or lymphatic vessels. [1] Examples of varices include: [citation needed] Varicose veins, large tortuous veins usually found on legs; Sublingual varices
The left gastric vein runs from right to left along the lesser curvature of the stomach. [2] It passes to the esophageal opening of the stomach, where it receives some esophageal veins. [2] It then turns backward and passes from left to right behind the omental bursa. It drains into the portal vein near the superior border of the pancreas. [2]
