title: A randomized controlled trial of gastric lavage prior to endoscopy for acute upper gastrointestinal bleeding.
abstract: OBJECTIVE
  We hypothesized that large volume gastric lavage prior to endoscopy for acute upper gastrointestinal bleeding would improve the quality of endoscopic examination.
  
  
  BACKGROUND
  Blood retained in the stomach can impair visualization during esophagogastroduodenoscopy. Patients with acute upper gastrointestinal bleeding and a retained gastric fundic pool during endoscopy may have worse outcomes than patients without a retained fundic pool. No trials to date have evaluated if large volume gastric lavage prior to endoscopy improves visualization during acute upper gastrointestinal bleeding.
  
  
  METHODS
  Patients with acute upper gastrointestinal bleeding were randomized to esophagogastroduodenoscopy alone or large volume tap water gastric lavage prior to esophagogastroduodenoscopy. The quality of endoscopic visualization was assessed using a 5-point scale. Clinical outcomes were compared for lavaged and nonlavaged patients.
  
  
  RESULTS
  A total of 39 patients were randomized. In 1 patient, lavage was unsuccessful. The quality of visualization was not significantly different between groups for the esophagus, gastric antrum, or duodenum but was significantly better for the gastric fundus for patients randomized to lavage (P = 0.02). There was no significant difference between groups for ability to define a bleeding source, achieve hemostasis, recurrent bleeding, need for repeat endoscopy, and length of stay or death. There were no complications.
  
  
  CONCLUSIONS
  Large volume gastric lavage prior to esophagogastroduodenoscopy for acute upper gastrointestinal bleeding is safe and provides better visualization of the gastric fundus.
