Estrategias para mejorar la tasa de detección de adenomas y pólipos serrados durante una colonoscopia

Gastroenterol. latinoam; 35 (2), 2024
Adenoma detection rate (ADR) is a key quality indicator in screening colonoscopy, closely linked to colorectal cancer (CRC) prevention. Currently, the minimum recommended ADR is > 30% with an aspirational goal of > 35%; and the sessile serrated lesion detection rate (SSLDR) minimum is > 7% with an aspira...
