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.
