¿Cómo puede ayudar la tecnología de Olympus a facilitar la inserción en el colon?

Durante mucho tiempo, el sistema ScopeGuide se consideró una herramienta de formación para endoscopistas principiantes. En un estudio clínico comparativo y aleatorio, los médicos residentes que usaron este sistema consiguieron una tasa de intubación cecal mucho mayor y necesitaron menos ayuda de los médicos expertos que aquellos médicos residentes que hicieron colonoscopias por radioscopia. (29)

Y el sistema ScopeGuide no solo ofrece ventajas para los médicos residentes: también aumenta la tasa de intubación cecal en el caso de los gastroenterólogos principiantes y expertos (30,31) y mejora los tiempos de intubación cecal y los índices de dolor de los pacientes. (31)

La última generación de colonoscopios EVIS EXERA III puede incluso potenciar estos efectos: los modelos CF-HQ190 y PCF-H190D con función ScopeGuide integrada también incorporan la tecnología de inserción responsiva, que reduce el tiempo de inserción cecal en aproximadamente un 20%. (32)

¿Por qué la inserción en el colon resulta complicada?

La tasa de intubación cecal es un indicador de calidad de la colonoscopia. Las referencias bibliográficas indican que un gastroenterólogo debería alcanzar el ciego en al menos el 90 % de las exploraciones para garantizar un servicio médico de gran calidad.

Para dominar la colonoscopia (p. ej., para conseguir una tasa de intubación cecal superior al 90 %) suele ser necesario hacer entre 200 y 250 exploraciones. (27) Pero, además de la experiencia, existen factores de riesgo como la edad del paciente, el sexo, la BMI, cirugías anteriores o calidad de preparación, que pueden afectar a la tasa de éxito de la incubación cecal. (27)

La intubación puede causar dolor en el colon sigma de los pacientes siendo ésta la zona con mayor tasa de dolor durante la colonoscopia (28)
