Core Tip	Rectal subepithelial lesions (SELs) often manifest as bumps with smooth surface in endoscopy. An efficient biopsy strategy is crucial to sampling for differentiation of pathological types. The transperineal core needle biopsy guided by endorectal ultrasound combined with contrast-enhanced ultrasound overcomes the limitations of previous guidances, such as sampling inadequacy, high risk of complications and exposure of radiation. In our case, unsuccessful transabdominal biopsy led to failure of pathological diagnosis. The patient underwent this new biopsy modality then, and the diagnosis was finally made. No complications occurred. We recommend this new strategy as a promising tool for rectal SELs biopsies.
