Muscle Retracting Sign in Colorectal Macronodular Lesions: Prevalence, ESD Outcomes, and Submucosal Cancer Predictors

Key Points

• The muscle retracting sign is prevalent in colorectal macronodular lesions.
• Findings suggest a strong correlation with submucosal cancer risk, with specifics not disclosed.
• Observational analysis of ESD outcomes reveals insights into therapeutic strategies for managing these lesions.
• Implications highlight the need for further validation of predictors, given the complexity of cancer diagnosis.
