ABSTRACT
ABSTRACT Gastrointestinal stromal tumors (GIST) are relatively rare lesions of mesenchymal origin, being more frequent in the stomach and small intestine. These are clinically asymptomatic lesions, and in advanced stages may present with nausea, vomiting, bleeding, abdominal pain, a palpable mass, and even intestinal obstruction. The only effective treatment consists of a complete tumor resection. We report two cases of GIST located in the distal rectum and evaluated with three-dimensional anorectal ultrasonography, a procedure of great value in identifying the size of the lesion, its involvement toward nearby structures and lymph node invasion.
RESUMO
RESUMO Os tumores estromais do trato gastrointestinal (GIST) são lesões relativamente raras de origem mesenquimal, sendo mais frequentes no estômago e intestino delgado. Clinicamente, são lesões assintomáticas e em estados avançados podem cursar com náusea, vômito, sangramento, dor abdominal, massa palpável e até obstrução intestinal. O único tratamento efetivo é a ressecção completa do tumor. Relatamos dois casos de GIST localizados no reto distal e avaliados com ultra-sonografia anorretal tridimensional, que se apresenta de grande valia na identificação do tamanho da lesão, acometimento de estruturas vizinhas e invasão linfonodal.
