Hugo Uchima et al. Underwater cap-suction pseudopolyp formation for endoscopic mucosal resection: a simple technique for treating flat, appendiceal orifice or ileocecal valve colorectal lesions
Underwater endoscopic mucosal resection is an effective technique; however, snare capture may be more challenging for flat lesions, or those at the appendiceal orifice or ileocecal valve. This novel technique uses underwater cap suction to create a pseudopolyp prior to resection. The method was safe, with high technical success rates and low recurrence.
