Abstract
A 70 year-old Japanese man with liver cirrhosis was referred to our hospital becauseof tarry stool. He had been taking hemodialysis for two years due to chronic renal failurefollowing lgA nephropathy. The patient had an iron-deficiency anemia with 7.9 g/dl ofserum hemoglobin concentration. Upper gastrointestinal endoscopic examination revealedcharacteristic erythematous diffuse spots in the gastric antrum. Biopsy specimen obtainedfrom the lesions demonstrated a pattern of vascular ectasia and fibromuscular hyperplasiain the erythematous mucosa, which was consistent with gastric antral vascular ectasia(GAVE). We used a heater probe treatment in this case. Follow-iup endoscopy performedfour months after several sessions of the heater probe treatment revealed multiple polypoidlesions arosen from the treated sites, The histological examination of the lesions showedhyperplastic polyps. These benign protruded lesions were considered to have occurred inassociation with the healing process of gastric ulceration. ln our knowledge, this is the firstreport on multiple hyperplastic polyps arosen after heater probe treatment for GAVE. H2 blocker which had been administered might have caused some effects.
