Portosystemic shunts versus endoscopic therapy for variceal rebleeding in patients with cirrhosis

Management of chronic liver failure until liver transplantation

Chronic liver failure is an important cause of morbidity and mortality and is the long-term consequence of many chronic liver diseases. In addition to determining the specific cause of the chronic liver disease, which may be amenable to targeted therapy, it is important to treat the sequelae of chronic liver failure effectively to improve quality of life, to prolong survival, and to provide a bridge to liver transplantation. Once a patient who has chronic liver failure develops hepatic decompensation, liver transplantation is the definitive treatment for those who qualify. Management of chronic liver failure is the focus of this article.

Future expectations in the prophylaxis of intestinal bleeding

Prophylaxis of gastrointestinal bleeding is attempted in widely varying situations. In NSAID-induced peptic ulcer, the advantage of selective cyclooxygenase 2 inhibitors with regard to gastrointestinal damage has yet to be translated into an advantage in overall morbidity. Strategies for primary and secondary prevention of variceal bleeding have been established. Therapy tailored to hepatic venous pressure gradient has the potential to achieve clinical relevance. Several methods have been developed to prevent postpolypectomy bleeding, but their optimal risk-tailored application has yet to be demonstrated. Although octreotide treatment seems to be beneficial in reducing the blood loss from angiodysplasias, controlled studies to determine its optimal use are awaited. Stress-ulcer prophylaxis is commonly applied in critically ill patients. Although data indicate that H2-receptor antagonists and omeprazole are effective in preventing clinically significant bleeding, evidence for an advantage with respect to length of hospital or intensive-care-unit stay, as well as mortality, is still lacking. Since there is misuse of acid-suppressing drugs on regular wards, in-house guidelines may offer the potential for saving costs and reducing inappropriate prescription.
