The natural history of cirrhosis has a symptomatic and asymptomatic stage. The symptoms include the development of ascites, hepatic encephalopathy, or variceal bleeding. The development of portal hypertension represents a critical transition point in the natural history of cirrhosis, contributing to, or directly responsible for all of these events. It is defined by an increase in intrahepatic vascular resistance to portal venous inflow, with the subsequent development of collateral vessels, such as esophageal or gastric varices. As portal pressures rise over time, however, the resulting increase in variceal size and wall tension translates into an increasing likelihood of rupture and bleeding, leading to death in about 30% of patients. Over the last twenty years, data have emerged regarding the role of tumor necrosis factor (TNFα) in portal hypertension from animal models as well as in vitro experiments. Portal hypertension is a condition characterized by vasodilatation and a hyperdynamic circulation, driven by relative overproduction of nitric oxide23. In animal trials using inhibitors of TNF it has been shown to decrease the development of the hyperdynamic circulatory state and portal pressure.24-25 Based on these data, investigators have examined the role of TNF inhibition with thalidomide. Significant improvement in blocking the development of the hyperdynamic circulation and portal pressures was demonstrated.26 Human trials have also show the efficacy of thalidomide in reducing portal pressures. In that these trials have shown promising results further investigation is
The role of capsule endoscopy (CE) in patients with obscure / occult gastrointestinal (GI) bleeding remains unclear. This pragmatic randomized controlled trial is designed to determine the diagnostic yield and clinical outcomes of patients with obscure GI bleeding who receive CE compared to those who receive usual standard care.
In unselected cirrhotic patients with bleeding esophageal varices to compare the influence on mortality rate, duration of life, quality of life, and economic costs of treatment of: - Emergency portacaval shunt, and - Emergency and long-term endoscopic sclerotherapy.
Upper gastrointestinal tract hemorrhage (UGIH) remains a major cause of morbidity and mortality . Nasogastric aspiration (NGA) is routinely performed in patients with UGIH to obtain important clinical data and make therapeutic decisions. But routine use of NGA remains controversial with studies reporting its usefulness and its redundant clinical information. Early esophagogastroduodenoscopy (EGD) is recommended by most gastrointestinal societies to allow for risk stratification and to perform endoscopic treatments. The results of the NGA may assist to differentiate between high-risk versus low-risk lesions. Our hypothesis is that presence of NGA can identify lesions that require endoscopic treatment and provides important clinical information to guide the treating physician. In addition, we hypothesized that the results of the NGA influence the clinical decision of the treating physician regarding the prediction of the need for endoscopic therapy. This observational randomized cross-sectional study will enroll consecutive patients with presumed UGIH and randomized them to NGA and no NGA recording its results. All patients will receive an EGD and its results will also be recorded. Subsequently, we will evaluate if the NGA is important in identifying endoscopically significant lesions. The information gained will help guide clinicians evaluating patient with UGIH.
Up to 5% of patients with recurrent gastrointestinal (GI) bleeding remain undiagnosed by EGD and colonoscopy, the presumed source of bleeding in these patients being the small intestine. These patients fall under the category of "obscure gastrointestinal bleeding," and frequently require an extensive diagnostic work-up. For these reasons, most patients who present with obscure or occult gastrointestinal bleeding typically undergo multiple endoscopic evaluations, including capsule endoscopy and various radiologic imaging studies, including enteroclysis, small bowel series, CT scan, angiography, and radionuclide scan. Recently, many centers (included the Brigham and Women's Hospital) have begun using capsule endoscopy and CT enterography (CTE) for evaluation of suspected small bowel pathology. This is an observational study enrolling patients referred to the Brigham and Women's Hospital for obscure gastrointestinal bleeding designed to compare the diagnostic yield of various diagnostic modalities, in particular capsule endoscopy and CT enterography in the evaluation of obscure gastrointestinal bleeding.
Patients with liver cirrhoses and recent history of variceal bleeding, with HVPG documented non response to medical therapy with non selective beta blockers +/- mononitrates or variceal rebleeding during adequate medical therapy will be randomized to undergo either multi-session endoscopic multi-band ligation and continuation of medication or TIPS placement. Best treatment for this group of cirrhotic patients is not known so far.
Observational study about the incidence of relative adrenal insufficiency in patients with cirrhosis and acute variceal bleeding; in patients with acute peptic gastrointestinal bleeding and without liver disease; and in patients with severe acute pancreatitis. This is a study using pharmaceutical specialties in the approved conditions of use.
To evaluate the role of lactulose in prevention of clinically overt hepatic encephalopathy (HE) in the setting of acute upper gastrointestinal bleeding in cirrhotic patients
Controlled and randomized study comparing combined treatment (nadolol and endoscopic ligation) versus nadolol associated with isosorbide mononitrate or prazosin according to hemodynamic response, in the prevention of esofagic verices rebleeding.
