Abstract

Although adenomas and serrated polyps are the preneoplastic lesions of colorectal cancer, only few of them will eventually progress to cancer. This review provides a comprehensive overview of the present and future of post-polypectomy colonoscopy surveillance. Post-polypectomy surveillance guidelines have recently been updated and all share the aim towards more selective and less frequent surveillance. We have examined these current guidelines and compared the recommendations of each of them. To improve the diagnostic yield of post-polypectomy surveillance it is important to find predictors of metachronous polyps that better identify high-risk individuals of developing advanced neoplasia. For this reason, we have also conducted a literature review of the molecular biomarkers of metachronous advanced colorectal polyps. Finally, we have discussed future directions of post-polypectomy surveillance and identified possible strategies to improve the use of endoscopic resources with the COVID-19 pandemic.

Resumen

Aunque los adenomas y los pólipos serrados son las lesiones preneoplásicas del cáncer colorrectal, solo algunas de ellas progresarán a cáncer. Esta revisión presenta una descripción del presente y el futuro de la vigilancia endoscópica tras la resección de pólipos. Las recomendaciones de vigilancia pospolipectomía se han actualizado recientemente y todas comparten el objetivo de una vigilancia más selectiva y menos frecuente. Hemos examinado estas directrices actuales y hemos comparado las recomendaciones de cada una de ellas. Para mejorar el rendimiento diagnóstico de la vigilancia posterior a la polipectomía es importante encontrar predictores de pólipos metacrónicos que identifiquen mejor a los individuos con alto riesgo de desarrollar neoplasias avanzadas. Por este motivo, también hemos realizado una revisión de la literatura de los biomarcadores moleculares de pólipos avanzados metacrónicos. Finalmente, hemos discutido las direcciones futuras de la vigilancia endoscópica tras la resección de pólipos e identificado posibles estrategias para mejorar el uso de recursos endoscópicos con la pandemia de COVID-19.
