title: Prevalence and natural history of gastric antral vascular ectasia in patients undergoing orthotopic liver transplantation.
abstract: OBJECTIVE
  To describe the prevalence and natural history of gastric antral vascular ectasia (GAVE) in patients with end-stage liver disease undergoing orthotopic liver transplantation (OLT).
  
  
  BACKGROUND
  GAVE is a well-recognized cause of gastrointestinal hemorrhage. Although 30% of patients with GAVE have liver disease, the prevalence of GAVE in patients with cirrhosis is not known.
  
  
  METHODS
  We reviewed clinical records of patients who underwent OLT at our institution from February 1, 1998 to June 2003. Demographic and clinical details were recorded with attention to findings during upper endoscopy before and after OLT.
  
  
  RESULTS
  A total of 597 patients underwent OLT, and 345 were evaluated preoperatively with esophagogastroduodenoscopy (EGD). Eight (2.3%) were found to have GAVE before OLT. Three of these eight underwent EGD after OLT, and GAVE was absent in all three. None of the patients with GAVE experienced gastrointestinal bleeding postoperatively.
  
  
  CONCLUSIONS
  GAVE was present in nearly 1 in 40 patients with end-stage liver disease who underwent EGD before OLT at our institution and appears to resolve after transplant. These findings are consistent with a previous report documenting resolution of GAVE after OLT.
