Varicele acute Varicocele Symptoms - Mayo Clinic
Varices are dilated submucosal veins, most commonly detected in the distal esophagus or proximal stomach. Varices are associated with portal hypertension of any cause including presinusoidal portal vein thrombosissinusoidal cirrhosis and postsinusoidal Budd Chiari syndrome causes the commonest being cirrhosis.
The most important predictor of hemorrhage is the size of varices; the larges varices are at highest risk of bleeding. In cirrhosis, portal pressures initially increase as a consequence of resistance to blood flow within the liver. This resistance is due mainly to fibrous tissue and regenerative nodules in the hepatic parenchyma. In addition to this structural resistance, there is intrahepatic vasoconstriction.
This is believed to be due to decreased production of varicele acute nitric oxide. However, portal hypertension occurs despite the compensatory formation of collaterals for 2 reasons: Varices are portosystemic collaterals that form after pre-existing vascular channels are dilated by portal hypertension.
Dilation generally is clinically significant varicele acute the hepatic venous pressure gradient HVPG is elevated link 12mm Hg normal mm Hg. The HVPG is defined as the gradient varicele acute the wedged hepatic venous pressure WHVP and the free hepatic venous pressure. The WHVP is measured varicele acute a threading a catheter down through the jugular vein into varicele acute hepatic vein and wedging it into a smaller branch.
Nonbleeding varices are generally asymptomatic. Once varices are bleeding, patients classically present with symptoms of an upper gastrointestinal hemorrhage such at hematemesis, passage of black or bloody stools, lightheadedness, or decreased urination. Associated signs of variceal hemorrhage include decompensated liver function manifested as jaundice, hepatic encephalopathy, worsened or new-onset ascites. Physical examination will likely reveal hypotension or shock in severe casespallor and stigmata of chronic liver disease such as spider angiomatas, varicele acute erythema, gynecomastia, or splenomegaly.
A rectal examination should be performed on all patients without obvious bleeding. A black tarry stool on the gloved finger suggests an upper gastrointestinal source, and further workup needs to be pursued. Hemoccult testing is not necessary because clinically significant bleeding should be apparent with visual inspection of the stool alone.
The gold varicele acute for the diagnosis of varices is esophagogastroduodenoscopy Varicele acute. It is generally recommended that varicele acute with cirrhosis undergo elective endoscopic screening for varices at the time of diagnosis and periodically thereafter visit web page no varicele acute small varices are detected Figure 1.
If screening EGD reveals appreciable visit web page varices, a size classification should be assigned.
Different size classification systems have been used over the years; however, varicele acute recent consensus meeting proposed that varices be categorized in only two grades, small and large. An appropriate cut-off varicele acute determined varicele acute be 5mm; that is, small varices are those less than 5mm and read article varices are those greater than 5mm.
Another procedure that is currently being studied for screening for varices is esophageal capsule endoscopy. Pilot studies suggest it is safe and well tolerated and does not require sedationalthough its sensitivity and cost effectiveness still need varicele acute be established. Varicele acute diagnosis of variceal hemorrhage is secured when endoscopy shows one of the following: Practice guidelines have been formulated by the American Association of Study of Liver Diseases AASLD regarding the prevention and management of gastroesophageal varices and variceal hemorrhage in cirrhosis.
Treatment of varices is best considered in three distinct phases: If a patient has small varices that have never bled and has no risk factors for a first variceal hemorrhage like high Child-Pugh score, continued alcohol use and presence of red wale markings, prophylactic strategies can be considered, although the long-term benefit has not been established. In our practice, primary prophylaxis for bleeding has often been reserved for those who have small varices with risk factors listed above and for all patients with large varices.
The varicele acute pharmacologic strategy for preventing variceal hemorrhage is use of nonselective beta blockers, particularly propranolol and nadolol. These medications reduce portal pressures both by decreasing cardiac output and varicele acute producing splanchnic vasoconstriction. A meta-analysis has also showed a statistically significant varicele acute in overall mortality.
Selective beta-blockers, such as atenolol and metoprolol, varicele acute less effective varicele acute are not currently recommended for primary prophylaxis.
Likewise, use of isosorbide mononitrate alone or with nonselective beta blockers is not currently recommended. Propranolol is usually vindeca varice at a dose of 20 mg twice daily and nadolol at a dose of 40 mg daily. Unfortunately, beta blockers have some significant side effects, so often the dose is simply adjusted to a maximally tolerated dose.
The most common side effects reported are lightheadedness, fatigue, shortness of breath, and impotence in check this out. Relative contraindications to the use of beta blockers include reactive airways disease, insulin-dependent diabetes with episodes of hypoglycemiaand peripheral vascular disease. Patients who meet criteria for primary prophylaxis but who cannot tolerate or have contraindications to beta blocker varicele acute should be considered for prophylactic endoscopic variceal varicele acute EVL.
Although studies have been conflicting, a recent consensus panel of experts concluded that both nonselective beta blockers and EVL are effective in preventing first variceal hemorrhage. The decision on whether to treat pharmacologically or via EVL should be based on patient characteristics and preferences, local resources, and expertise.
Nitrates either alone or in combination with blockersshunt therapy, or sclerotherapy should not be used in the primary prophylaxis of variceal hemorrhage.
Cirrhotic patients with suspected acute variceal hemorrhage should be admitted directly to an intensive care unit setting for frequent monitoring and aggressive management Figure 2. While still in the emergency department, varicele acute resuscitation can begin by securing large-bore IVs and sending bloodwork to the lab, including a type and crossmatch for blood products.
Volume resuscitation should be undertaken promptly but with caution because vigorous resuscitation can actually increase portal pressures to levels higher than baseline, thereby prompting rebleeding. In our practice we usually start the resuscitation with normal saline and switch to blood or albumin varicele acute bothonce available, with the goal to maintain hemodynamic stability.
Transfusion of fresh frozen plasma and continue reading can be considered in patients with a severe coagulopathy or thrombocytopenia.
Low threshold should be taken to intubate the patient for airway protection, particularly if the patient is in shock or encephalopathy, because aspiration of blood often occurs. Antibiotics are routinely administered in cirrhotic patients who are admitted to the hospital with variceal hemorrhage. Several randomized clinical trials varicele acute able to show that antibiotics not only decreased the rate of bacterial infection in see more patients but also decreased the incidence of early rebleeding and increased overall survival.
The optimal antibiotic and duration is unclear, because benefit was detected from many different regimens. In general, oral norfloxacin at doses of mg twice daily for 7 days or IV ciprofloxacin in patients in whom oral administration is not possible is the recommended antibiotic. In patients with varicele acute cirrhosis or at hospitals with a high incidence of quinolone resistance, ceftriaxone at a dose of 1g IV daily may be preferable.
Pharmacologic therapy to varicele acute portal pressures is critically important and should be considered first-line treatment for acute variceal hemorrhage. It should be initiated as varicele acute as the diagnosis of variceal hemorrhage is suspected and before EGD. The most common pharmacologic agent used in the United States for this purpose is octreotide, a somatostatin analogue that causes splanchnic vasoconstriction. This agent should be varicele acute ideally for 5 days, even after bleeding is controlled.
Vasopressin most often used with nitroglycerin is the most potent splanchnic vasoconstrictor, but it is rarely used for control of variceal hemorrhage due to its multiple vascular side effects including myocardial and mesenteric ischemia and infarction.
Terlipressin is a vasopressin analogue that has significantly fewer side effects. It is effective in controlling variceal hemorrhage and reducing mortality. It is administered at an initial dose of 2mg IV every 4 hours and then titrated down to 1mg every 4 hours once bleeding is controlled. Terlipressin is currently used extensively varicele acute other parts of the world but is not widely available in the United States.
Even though pharmacologic therapy can be effective at controlling suspected variceal hemorrhage, EGD should be performed as soon as possible to confirm varicele acute diagnosis and implement endoscopic therapy.
Sclerotherapy, widely used in the past, is now nearly obsolete because of risk of complication and improvement in EVL devices. Indeed, recent consensus determined EVL to be the preferred form of endoscopic therapy for acute esophageal variceal varicele acute, although sclerotherapy is still recommended in patients in whom Varicele acute is not technically feasible. Gastric varices, which are often not amenable to either EVL or sclerotherapy, may be more difficult to treat. N-butylcyanoacrylate varicele acute injected directly into the varix has been shown to be effective for control of bleeding gastric varices.
If this agent is not available varicele acute in the case of an inexperienced operator, TIPS should be considered as first line therapy. Portal decompressive therapy, either shunt surgery or TIPS, should then be considered. As TIPS has become more widely available, this is becoming the preferred decompressive procedure. However, performance of varicele acute TIPS or shunt surgery largely depends on local expertise.
Because TIPS and surgery are both invasive procedure with a high risk of complication, they are reserved for patients who fail pharmacologic and endoscopic therapy. A randomized controlled trial varicele acute reported reduced mortality and rebleeding rates with early TIPS within 48 hours after variceal hemorrhage. However, this needs varicele acute be validated with varicele acute studies.
Balloon tamponade applies direct pressure to the ruptured varix and can be highly effective for immediate control of variceal hemorrhage.
Unfortunately, recurrent varicele acute is common after the balloon is decompressed, varicele acute balloon tamponade is associated with varicele acute fatal complications such necrosis or varicele acute of the esophagus. Therefore, tamponade should be varicele acute only as a rescue procedure and a bridge to more definitive therapy maximum 24 hourssuch as TIPS, varicele acute cases of uncontrolled varicele acute. Patients who survive an episode of acute variceal hemorrhage are at varicele acute risk of rebleeding and death.
Several studies have demonstrated that combination endoscopic plus pharmacologic therapy is the varicele acute effective means of preventing secondary bleeding episodes.
In terms of endoscopic therapies, EVL is the method of choice for secondary prophylaxis. After inital control of the bleeding, EVL should be repeated at 1- to 2-week intervals until varices are completely obliterated. This usually requires 2 to 4 sessions. Once the varices are obliterated, EGD is repeated every 3 to 6-months to evaluate the need for repeat EVL. Complications of EVL include chest pain, dysphagia and ulcers that form at the site of the band ligation, which universally form varicele acute can cause significant bleeding.
Although not varicele acute proven to be effective, proton pump inhibition is sometimes used in an attempt to decrease the bleeding risk from these band ulcer sites for 2 weeks after an EVL procedure. Optimal pharmacologic therapy for secondary prophylaxis appears to be a combination of a nonselective beta blocker and a nitrate. However, this varicele acute has significantly greater side effects compared to beta blockers alone and is overall poorly tolerated.
In our clinical practice, most patients end up taking beta blockers alone. Clinical opinion is divided on the need to continue pharmacologic therapy once varices are varicele acute obliterated, but current guidelines suggest that pharmacologic therapy should be continued at the highest tolerated dose indefinitely.
TIPS or shunt surgery can be considered in patients who experience recurrent bleeding despite combination pharmacologic and endoscopic therapy. Most varicele acute haemorrhages can be controlled with these measures. However, because acute variceal bleeding often precipitates a clinical deterioration and worsening of liver synthetic function, patients who are otherwise transplant candidates should be referred to a liver transplantation center for a liver transplant evaluation after recovery.
