ABSTRACT

BACKGROUND:

Gastric antral vascular ectasia is a disorder whose pathogenetic mechanism is unknown. The endoscopic treatment with argon plasma coagulation has been considered one of the best endoscopic therapeutic options.

AIM:

To analyze the endoscopic and clinical features of gastric antral vascular ectasia and its response to the argon plasma coagulation treatment. PATIENTS AND

METHODS:

Eighteen patients were studied and classified into two groups group 1 - whose endoscopic aspect was striped (watermelon) or of the diffuse confluent type; group 2 - diffuse spotty nonconfluent endoscopic aspect.

RESULTS:

Group 1 with eight patients, all having autoimmune antibodies, but one, whose antibodies were not searched for. Three were cirrhotic and three had hypothyroidism. All had gastric mucosa atrophy. In group 2, with 10 patients, all had non-immune liver disease, with platelet levels below 90.000. Ten patients were submitted to argon plasma coagulation treatment, with 2 to 36 months of follow-up. Lesions recurred in all patients who remained in the follow-up program and one did not respond to treatment for acute bleeding control.

CONCLUSION:

There seem to be two distinct groups of patients with gastric antral vascular ectasia one related to immunologic disorders and other to non-immune chronic liver disease and low platelets. The endoscopic treatment using argon plasma coagulation had a high recurrence in the long-term evaluation.
RESUMO
RACIONAL "Watermelon stomach" ou ectasia vascular do antro gástrico é uma doença de etiopatogenia desconhecida. O tratamento endoscópico através da coagulação com plasma de argônio é considerado uma das melhores opções terapêuticas.

OBJETIVO:

Analisar os aspectos clínicos e endoscópicos da ectasia vascular do antro gástrico e a resposta ao tratamento com coagulação com plasma de argônio. PACIENTES E

MÉTODOS:

Dezoito pacientes foram estudados e classificados em dois grupos grupo I - oito pacientes que exibiam ectasia vascular do antro gástrico de aspecto difuso confluente ou estriado. Grupo II - 10 pacientes que apresentavam aspecto difuso pontilhado não-confluente.

RESULTADOS:

Todos os pacientes do grupo I apresentavam auto-anticorpos, exceto um paciente no qual não foi pesquisado. Três eram cirróticos, três tinham hipotireoidismo e todos apresentavam gastrite atrófica. No grupo II, todos tinham doença hepática não-autoimune, com plaquetas menores que 90.000. Dez pacientes foram submetidos a tratamento com coagulação com plasma de argônio, com 2 a 36 meses de seguimento. A ectasia vascular do antro gástrico recorreu em todos os pacientes que continuaram em acompanhamento e um paciente não respondeu ao tratamento para controle de sangramento agudo.

CONCLUSÃO:

Observou-se a existência de dois grupos distintos de pacientes com ectasia vascular do antro gástrico um grupo associado a distúrbios imunológicos e outro com doença hepática não auto-imune e plaquetopenia. O tratamento com coagulação com plasma de argônio apresentou alta recurrência das ectasias vasculares.
