title: Endoscopic injection therapy in bleeding Mallory-Weiss syndrome: a randomized controlled trial.
abstract: BACKGROUND
  Endoscopic injection is widely used in the therapy of bleeding gastroduodenal ulcers, but its role in the management of bleeding Mallory-Weiss tears has not been properly assessed.
  
  
  METHODS
  Sixty-three patients undergoing emergency endoscopy in whom there was a high index of suspicion that a Mallory-Weiss tear was the source of bleeding were randomly assigned to undergo endoscopic injection therapy (epinephrine and polidocanol) or no endoscopic therapy in 2 university-affiliated hospitals. Rates of recurrent bleeding, transfusion requirements, complications, mortality, and length of hospital stay were determined for both groups of patients.
  
  
  RESULTS
  Bleeding recurred in 8 patients in the control group versus only 2 in the endoscopic treatment group (25.8% vs. 6.2%, p < 0.05). Hospital stay was longer for the control group (5.5 +/- 0.2, median 6.0, range 2.0-8.0 days vs. 3.4 +/- 0.2, median 3.0, range 2.0-6.0 days; p < 0.001). There was a trend toward a higher transfusion requirement after endoscopy in the control group versus the patients treated by injection (0.9 +/- 0.2, median 0.0, range 0.0-4.0 units vs. 0.2 +/- 0.1, median 0.0, range 0.0-2.0 units; p = 0.09). No complications or adverse events caused by endoscopic injection were noted. Two patients in the control group died of causes unrelated to bleeding.
  
  
  CONCLUSIONS
  Endoscopic injection therapy is a useful option in the management of patients with Mallory-Weiss syndrome at high risk for recurrent bleeding.
