Natural History of Mallory-Weiss Tear in African American and Hispanic Patients

The aim of this study was to determine the natural history of Mallory-Weiss tear (MWT) in African American and Hispanic patients. We retrospectively reviewed medical records of all patients with acute upper gastrointestinal bleeding over a 10-year period. Endoscopic diagnosis of MWT was made in 12% (n = 698) of all patients with acute upper gastrointestinal bleeding. More than half of our patients with MWT did not have a preceding history of retching or vomiting. Bleeding episodes were hemodynamically significant in 216 (31%) patients. Most of the patients with MWT (80%) had an uneventful and short hospital stay (range, 1-4 days). Recurrent upper gastrointestinal bleeding within 30 days occurred in 84 (12%) patients. Overall mortality was 10%; endoscopic hemostasis failure and associated comorbidities were the common culprits.
