To see if either method of treatment for Watermelon Stomach shows better results

Study summary:

Watermelon stomach (WS) is endoscopically recognized by characteristic stripes of angioectasias involving primarily the antrum, and causes transfusion-dependent anemia in the majority of patients. Current endoscopic treatment options, including argon plasma coagulation (APC) Endoscopic cryotherapy is a novel technique that has the potential to safely and more effectively treat WS by virtue of its mechanism of injury and mode of application.


Inclusion Criteria: 1. Confirmed WS at endoscopy that is associated with significant anemia (Hb < 10 g/dl) and/or overt bleeding (melena, hematochezia or hematemesis) and/or blood transfusions within the past 6 months 2. Able to give informed consent 3. Age > 18 years Exclusion Criteria: 1. Endoscopic or histological findings inconsistent with WS 2. Known coagulopathy (INR > 2), severe thrombocytopenia (platelet count < 50,000), or bleeding diathesis 3. Endoscopic treatment of WS within the past month 4. Unable or unwilling to give informed consent.
