Abstract:
A 78-year-old male on warfarin for deep venous thrombosis is referred to us for resection of a sessile polyp in the cecum. A high-definition Fujifilm BL-7000 processor, virtual chromoendoscopy, and EC-760ZP-V/L magnifying endoscope were used. Diathermy source, ERBE VIO 3. Auto cut mode, Effect 5, 80 watts, and Soft coagulation mode, Effect 5, 60 watts. Underwater polypectomy ensued with resection in two fragments. The resection bed was invaginated into the appendiceal orifice, hence no other measures were considered to prevent delayed bleeding. No complications were reported. The histopathological study found a tubulovillous adenoma with lesion-free borders.
