RESUMO
Upper gastrointestinal bleeding occurs so rapidly that emergency measures are required to avoid exsanguination. Many diseases cause bleeding from the gastrointestinal tract. Patients with upper gastrointestinal bleeding must be quickly assessed and resuscitated. An endoscopy is the diagnostic procedure of choice because of its high rate of accuracy and immediate therapeutic potential. An endoscopy however, must be performed only following adequate resuscitation and clinical assessment of the patient. Recently, reports have described the usefulness of endoscopic O-ring band ligation in the management of upper gastrointestinal bleeding. Endoscopic O-ring band ligation is mucosal ligation using intraluminal negative pressure with an elastic O-ring. We performed an emergency endoscopy in 3 patients who had massive or recurrent episodes of upper gastrointestinal bleeding, identified as having resulted from Dieulafoy lesion and Anisakiasis. We tried to perform an endoscopic ligation using an O-ring band, and were successful in achieving hemostasis. Our conclusion is that endoscopic ligation using an O-ring band can be used effectively to control active upper gastrointestinal bleeding resulting from Anisakiasis and a Dieulafoy lesion.
