I have heard of staples being expelled through the vagina, but not the rectum. Staples are usually meant to stay where they are put during surgery unless they cause a problem. When you had the bowel pain, was it around the time you noticed the staples coming out? May I ask how many you have lost? It sounds really painful, and I am a bit surprised your doctor wants to wait until 6/18 for a scan, given he's never seen anything like that before. I would suggest the next time you have pain like that, go to the ER. Obviously something is up. When you are in pain like that, your body is telling you something isn't right. Best of luck to you. I hope you find some answers soon.
