Summary
A case of arteriovenous malformation in a gastric polyp in a 60-year-old male complicated
by profuse bleeding after endoscopic polypectomy, and treated successfully by emergency
surgery, is presented. The vascular abnormality was clearly visualized by endoscopic
ultrasonography (EUS) prior to endoscopic removal of the polyp. Although endoscopic
coagulation of the pedicle proceeded slowly and with the utmost care causing apparently
adequate coagulation of the stalk, the depth, of coagulation appeared insufficient
to prevent major haemorrhage. From this experience we would be inclined to recommend
EUS examination of the pedicle of large polypoid lesions to document the size of the
vascular structure before endoscopic transection is carried out.
