Bleeding Esophageal Varices: overview, causes, and Risk factors

Single measurements are useful in the prognosis of both compensated and decompensated cirrhosis, while repeat measurements are useful to monitor response to pharmacological therapy and progression of liver disease. Limitations to the generalized use of hvpg measurement are the lack of local expertise and poor adherence to guidelines that will ensure reliable and reproducible measurements (14 as well as its invasive nature. Gastroesophageal varices are the most relevant portosystemic collaterals because their rupture results in variceal hemorrhage, the most common lethal complication of cirrhosis. Varices and variceal hemorrhage are the complications of cirrhosis that result most directly from portal hypertension. Patients with cirrhosis and gastroesophageal varices have an hvpg of at least 1012 mmHg (15, 24). Gastroesophageal varices are present in approximately 50 of patients with cirrhosis. Their presence correlates with the severity of liver disease ( Table 2 while only 40 of Child A patients have varices, they are present in 85 of Child C patients (25). Patients with primary biliary cirrhosis may develop varices and variceal hemorrhage early in the course of the disease even in the absence of established cirrhosis (26).

In addition to motorkleding this structural resistance to blood flow, there is an active intrahepatic vasoconstriction that accounts for 2030 of the increased intrahepatic resistance (8 and that is mostly due to a decrease in the endogenous production of nitric oxide (9, 10). Portal hypertension leads to the formation of porto-systemic collaterals. However, portal leg hypertension persists despite the development of these collaterals for 2 reasons: 1) an increase in portal venous inflow that results from splanchnic arteriolar vasodilatation occurring concomitant with the formation of collaterals (11 and 2) insufficient portal decompression through collaterals as these have. Therefore, an increased portal pressure gradient results from both an increase in resistance to portal flow (intrahepatic and collateral) and an increase in portal blood inflow. The preferred, albeit indirect, method for assessing portal pressure is the wedged hepatic venous pressure (whvp) measurement, which is obtained by placing a catheter in the hepatic vein and wedging it into a small branch or, better still, by inflating a balloon and occluding. The whvp has been shown to correlate very closely with portal pressure both in alcoholic and nonalcoholic cirrhosis (13). The whvp is always corrected for increases in intraabdominal pressure (e.g., ascites) by subtracting the free hepatic vein pressure (fhvp) or the intraabdominal inferior vena cava pressure, which act as internal zeroes. The resultant pressure is the hepatic venous pressure gradient (hvpg which is best accomplished with the use of a balloon catheter, usually taking triplicate readings and, when measured with a proper technique, is very reproducible and reliable (14). Since it is a measure of sinusoidal pressure, the hvpg will be elevated in intrahepatic causes of portal hypertension, such as cirrhosis, but will be normal in prehepatic causes of portal hypertension, such as portal vein thrombosis. The normal hvpg is 35 mmHg. The hvpg and changes in hvpg that occur over time have predictive value for the development of esophagogastric varices (15, 16 the risk of variceal hemorrhage (1719 the development of non-variceal complications of portal hypertension (17, 20, 21 and death (19, 2123).

Level of evidence, description, level left a, data derived from multiple randomized clinical trials or meta-analyses. Data derived from a single randomized trial, or nonrandomized studies. Level c, only consensus opinion of experts, case studies, or standard-of-care. Cirrhosis, the end stage of any chronic liver disease, can lead to portal hypertension. Portal pressure increases initially as a consequence of an increased resistance to flow mostly due to an architectural distortion of the liver secondary to fibrous tissue and regenerative nodules.

Low blood pressure, paleness, rapid heart rate, what causes esophageal varices? The root cause of esophageal varices is liver disease, such as cirrhosis of the liver. The scarring that happens with cirrhosis can cause portal hypertension, which is an increase in pressure in the veins of the liver. Because of this increased pressure, blood can't flow through the liver properly. The backup of blood from the liver can cause extra veins to form in the esophagus and stomach. These veins, or varices, are thinner and more fragile than normal blood vessels.

Since then, a number of randomized controlled trials have advanced our approach to managing variceal hemorrhage. Three international consensus conferences have been held (baveno iii in 2000, baveno iv in 2005, and an aasld/easl single topic conference in 2007) in which experts in the field have evaluated the changes that have occurred in our understanding of the pathophysiology and management. In this updated practice guideline we have reviewed the randomized controlled trials and meta-analyses published in the last decade and have incorporated recommendations made by consensus. Grading System for Recommendations, classification, description, class. Conditions for which there is evidence and/or general agreement that a given diagnostic evaluation, procedure or treatment is beneficial, useful, and effective. Class ii, conditions for which there is conflicting evidence and/or a divergence of opinion about the usefulness/efficacy of a diagnostic evaluation, procedure or treatment.

As with other practice guidelines, this guideline is not intended to replace clinical judgment but rather to provide general guidelines applicable to the majority of patients. They are intended to be flexible, in contrast to standards of care, which are inflexible policies designed to be followed in every case. Specific recommendations are based on relevant published information. To more fully characterize the quality of evidence supporting recommendations, the Practice guidelines Committee of the aasld requires a class (reflecting benefit versus risk) and level (assessing strength or certainty) of evidence to be assigned and reported with each recommendation (. Table 1, adapted from the American College of Cardiology and the American heart Association Practice guidelines (3, 4). When little or no data exist from well-designed prospective trials, emphasis is given to results from large series and reports een from recognized experts. Further controlled clinical studies are needed to clarify aspects of this statement, and revision may be necessary as new data appear. Clinical considerations may justify a course of action that differs from these recommendations. These recommendations are fully endorsed by the American Association for the Study of liver Diseases and the American College of Gastroenterology.
