title: Results of an upper endoscopy protocol in liver transplant candidates.
abstract: OBJECTIVE
  our aims is to understand endoscopic findings from a preoperative systematic study of patients with hepatic cirrhosis who were candidates for transplantation and their impact on a protocol for primary and secondary prophylaxis of variceal haemorrhage.
  
  
  METHODS
  this study involves a retrospective evaluation of upper digestive tract lesions detected before inclusion and a prospective evaluation of new episodes of variceal haemorrhage, associated mortality rates, and factors that are likely to be involved in the development of this condition. Primary prophylaxis with beta-blockers was considered indicated in cases of varices of grande II or greater or with signs associated with increased risk. Secondary prophylaxis was essentially always associated with medical and endoscopic treatment.
  
  
  RESULTS
  of 134 patients, there were 9 deaths, with a median time on the waiting list of 3 months. Of all patients, 33.6% presented with high risk oesophageal varices, 11.2 % with gastric varices, 42.6% with portal hypertensive gastropathy, and 26.9% with peptic lesions. Primary prophylaxis was indicated in 33 of 90 patients, and was initiated in almost half of the cases as a results of the study. Optimum fulfiment of the pre-established objectives was 75.3%. The incidence of new haemorrhagic events due to varices was 10.4% and accounted for almost half of the deaths during the monitoring period. The only statistically significant predictive factors were the presence of gastrict varices and previous history.
  
  
  CONCLUSIONS
  upper endoscopy should play a role in the preoperative examination of liver transplant candidates due to the significant impact it has on subsequent management.
