A man in his 60s presented with a positive fecal occult blood test during a health checkup. He underwent lower gastrointestinal endoscopy, revealing multiple polyps distributed throughout his entire large intestine. This led to the decision for endoscopic treatment. During the procedure, two pedunculated polyps were found entangled in the ascending colon. Both polyps displayed signs of ischemia, appearing dark purple, and the pedicles were under tension. Considering the potential risk of perforation, the procedure was ceased after observation-only, and surgical resection was deemed necessary. Subsequently, while conducting preoperative marking with an endoscope, both lesions had spontaneously detached, resulting in ulcers on the pedicles. No abdominal symptoms were observed throughout the disease course, and no melena or tumor excretion was confirmed. This case represents a rare and valuable instance of the simultaneous dislodgement of two colonic polyps observed over time with an endoscope.
