An 8-year-old boy was hospitalized with fresh bloody stool passage for 1 week. He underwent colonoscopy that revealed 1 large polyp in the rectosigmoid junction. The polyp was too large to be encircled by the snare. Laparoscopic-assisted colonoscopic polypectomy was performed successfully to remove this large polyp without the need for segmental resections. This patient treated using this technique were discharged 2 days after the procedure and returned to full activity within 3 to 4 days. There were no complications.
