Review article: definition and diagnosis in portal hypertension--continued problems with the Baveno consensus?
The goals of the Baveno workshops were to develop consensus definitions of key events related to portal hypertension and variceal bleeding, and to produce guidelines to facilitate the conduct and reporting of clinical trials. The consensus definitions concern the diagnosis of active bleeding, failure to control bleeding, the criteria to distinguish continuing bleeding from rebleeding, and the means of assessing failure to prevent rebleeding. The guidelines concern the timing of diagnostic endoscopy, the policy for blood volume restitution, the measures to prevent infection and encephalopathy, and the treatment options for acute bleeding, as well as primary and secondary prophylaxis. The intention of the experts who developed the guidelines was that, as feedback from their practical application develops, they should be adapted to better fit the practical needs. The applicability of the Baveno definitions has been evaluated in a study where the definitions of clinically significant bleeding, failure to control bleeding, the time frame for the acute bleeding episode and the definition of rebleeding were tested. The main criticism raised in this study was that tachycardia, one of the criteria that define failure to control bleeding, was misleading in 15% of patients who had the symptom but were not bleeding.
