Esophageal varices are extremely dilated sub-mucosal veins in the lower third of the esophagus. [1] They are most often a consequence of portal hypertension, [2] commonly due to cirrhosis. [3] People with esophageal varices have a strong tendency to develop severe bleeding which left untreated can be fatal.
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 ...
Esophageal varices and gastric varices result from collateral circulation in the esophagus and stomach (a process called portacaval anastomosis). [40] When the blood vessels in this circulation become enlarged, they are called varices. Varices are more likely to rupture at this point. [9] Variceal rupture often leads to severe bleeding, which ...
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; Esophageal varices, commonly stemming from cirrhosis of the liver, also known as oesophageal varicose
What causes lower left abdominal pain? Lower left abdominal pain can have many causes, ranging from minor to serious, says Andrew Boxer, M.D., gastroenterologist of Gastroenterology Associates of ...
The esophageal veins drain blood from the esophagus to the azygos vein, in the thorax, and to the inferior thyroid vein in the neck. It also drains, although with less significance, to the hemiazygos vein, posterior intercostal vein and bronchial veins. [citation needed] In the abdomen, some drain to the left gastric vein which drains into the ...
The inferior end of the esophagus and the superior part of the rectum are potential sites of a harmful portocaval anastomosis. [1] In portal hypertension, as in the case of cirrhosis of the liver, the anastomoses become congested and form venous dilatations. Such dilatation can lead to esophageal varices and anorectal varices. Caput medusae can ...
Once devascularization is complete, the esophagus is clamped in two areas with esophageal clamps, and esophageal transection is done at the level of the diaphragm. The anterior muscular and mucosal layers are divided, but the posterior layer is left intact. Sutures are then placed and the divided varices are occluded.
