493 ENDOSCOPIC FULL-THICKNESS RESECTION IS FEASIBLE FOR T1 COLORECTAL CANCERS - A DUTCH NATIONWIDE PROSPECTIVE REGISTRY COHORT STUDY

For T1 colorectal cancer (CRC) endoscopic resection is an attractive alternative to surgical resection due to lower morbidity and mortality. However, conventional polypectomy often leads to suboptimal histologic risk assessment. Exact risk stratification with certainty about resection margin status and presence of histological risk factors for lymph node metastasis (LNM) is crucial for further decision making. endoscopic full-thickness resection (eFTR) could serve as a valid diagnostic and therapeutic treatment option for T1 CRC.
