Case report highlights using endoscopic ultrasonography and ligation-assisted resection for diagnosis of cancer spread.
Endoscopic ultrasonography (EUS) plays a crucial role in characterizing subepithelial lesions (SELs) and enabling definitive pathological diagnosis through EUS-guided fine-needle aspiration/biopsy [1] [2] [3]. Some experts advocate surveillance with EUS for SELs originating from the muscularis propria that are less than 2 cm in diameter [4]. Here, we present a case of colonic metastasis from cervical carcinoma that was successfully diagnosed using ligation-assisted endoscopic full-thickness resection (EFTR) ([Video 1]).
