Retrospective analysis of iatrogenic Mallory-Weiss tears occurring during upper gastrointestinal endoscopy.

BACKGROUND/AIMS: This study was made to determine the incidence and natural history of iatrogenic Mallory-Weiss tears.

PATIENTS AND METHODS: We retrospectively analyzed twelve cases of iatrogenic Mallory-Weiss tears identified from 2,461 consecutive upper gastrointestinal endoscopies performed at our institution over a period of twenty-two months.

RESULTS: In all cases, bleeding stopped spontaneously without the need of blood transfusions, endoscopic hemostasis therapy or any other interventions. Eight patients (67%) had retching or struggling during the procedure. Hiatus hernias were noted in three patients (25%).

CONCLUSIONS: Iatrogenic Mallory-Weiss tears are rare and generally have a benign course. They tend to occur mostly in patients who have experienced excessive retching or struggling during endoscopy.
