Pólipos diminutos. ¿Qué hacer con ellos?
Resumen
Introducción: La extirpación de pólipos diminutos con características endoscópicas no neoplásicas sin estudio histológico o la no resección de los mismos son alternativas planteadas para minimizar riesgos y costos.
Objetivo: Determinar la presencia de pólipos diminutos (5 mms. de diámetro o menos) y su naturaleza histológica para evaluar el impacto clínico de extirparlos o dejarlos in situ, o extirparlos y no enviarlos a estudio histológico.
Pacientes y métodos utilizados: Con éste fin se evaluaron 217 colonoscopias practicadas consecutivamente, con resección y estudio histológico de los pólipos evidenciados.
Resultados: 26/63 pólipos diminutos (41,26%) presentaron riesgo carcinogénico para el paciente de haberse dejado in situ, con información inapropiada para determinar tiempo de seguimiento en caso de haberse resecados y descartados sin estudio histológico (entre ellos 2 displasias de alto grado).
Conclusiones: 1. Un alto porcentaje de pólipos diminutos presenta potencial carcinogénico y su estructura microscópica debe ser evaluada con fines pronósticos, de seguimiento o para determinar conductas a seguir. 2. Nuevas tecnologías pueden contribuir a una mejor selección de pólipos que no requieran ser resecados o estudiados histológicamente, pero mientras no sean adecuadamente validadas es prudente continuar con la estrategia de resecar y estudiar histológicamente.
