Resumen:

Gastric neuroendocrine tumors constitute 6.9% of all gastrointestinal neuroendocrine tumors and approximately 1% of all gastric neoplasms. They comprise a wide group of tumors that may or may not be secreting, and with very different biological behavior. Although most of them are benign, a small percentage have an aggressive behavior, with metastatic capacity and a poor survival. Given its relatively indolent course, sometimes the diagnosis results from a fortuitous finding, or less commonly when a complication (hemorrhage or obstruction) arises. Upper endoscopy with immunohistochemical analysis of the biopsy is essential for diagnosis. Tomography is the choice for staging. Lymph node dissemination is rare, and lymphatic emptying is not indicated except in cases of undifferentiated tumors or with visible lymphadenopathy intraoperatively, so the laparoscopic approach is especially attractive. The objective of this communication is to present three cases of laparoscopic resolution of gastric neuroendocrine tumors in our department.


Los tumores neuroendócrinos gástricos constituyen el 6,9% de todos los tumores neuroendócrinos del tubo digestivo, y el 1% de todas las neoplasias gástricas aproximadamente. Comprenden un amplio grupo de tumores que pueden ser secretantes o no, y con muy distinto comportamiento biológico. Si bien la mayoría de ellos son benignos, un pequeño porcentaje tiene un comportamiento agresivo, con capacidad metastásica y una pobre sobrevida. Dado su curso relativamente indolente, en ocasiones el diagnóstico resulta de un hallazgo fortuito, o menos comúnmente cuando surge alguna complicación (hemorragia u obstrucción). Para el diagnóstico es imprescindible la endoscopía alta con el análisis inmunohistoquímico de la biopsia. La tomografía es de elección para la estadificación. La diseminación ganglionar es infrecuente, y no está indicado un vaciamiento linfático a no ser en casos de tumores indiferenciados o con adenopatías visibles en el intraoperatorio, por lo que el abordaje laparoscópico resulta especialmente atractivo. El objetivo de esta comunicación es presentar tres casos de tumores neuroendócrinos de localización gástrica de resolución laparoscópica en nuestro servicio.
