ABSTRACT

La ectasia vascular antral gástrica (GAVE) o watermelon stomach es un causa de hemorragia digestiva alta cuyo reconocimiento se ha incrementado, la cual posee características endoscópicas e histológicas típicas. La enfermedad es más frecuente en mujeres ancianas y varias entidades asociadas han sido bien establecidas. Si bien algunos pacientes con gastropatía asociada a la hipertensión portal pueden presentar un aspecto similar a la GAVE, la distinción resulta de interés a los fines de elegir una terapéutica apropiada. El objetivo de este estudio es analizar las características clínicas y el tratamiento de un grupo de pacientes con GAVE evaluados en nuestra institución. Asimismo, se realizóuna revisión de la bibliografía actual. Seis mujeres tres hombres con GAVE fueron admitidos en el Hospital Británico de Buenos Aires entre noviembre de 1998 y enero de 2004. Se realizó biopsia endoscópica en ocho pacientes, siendo consistente con GAVE en todos los casos. Cuatro pacientes con anemia crónica como única manifestación fueron exitosamente tratados con suplementos de hierro. Se realizó tratamiento endoscópico en cuatro pacientes, tres de ellos con electrocauterio bipolar y uno con coagulación con argón plasma. El paciente restante fue sometido a antrectomía. Se observó resolución del sangrado en todos los casos, más allá de la terapéutica instituída.


The gastric antral vascular ectasia (GAVE) or watermelon stomach is an increasingly recognized cause of persistent upper gastrointestinal bleeding, which has typical endoscopic and histological findings. This disease is most frecuent in elderly women, and several associated conditions have been well established. Some patients with severe portal hypertensive gastropathy may have a GAVE like appearence. Nevertheless, a correct diagnosis is relevant in order to choose an appropiate treatment. The objective of the current study is to analize the clinical features and treatment of a group of patients with GAVE evaluated at our Institution. A review of the current literature was also performed. Six women and three men with GAVE were admitted at the Buenos Aires British Hospital between November 1998 and January 2004. Endoscopic biopsy was performed in eight patients and was consistent with GAVE in all cases. Four patients with chronic anaemia as unique manifestation were succesfully treated with iron supplements. Endoscopic treatment was performed in 4 patients, 3 of them were treated with bipolar electrocautery and 1 with argon plasma coagulation. An antrectomy was carried out in the ninth patient. The resolution of the bleeding was observed in all cases with the different therapeutics options used.
