It is possible for small bowel polyps to pass out of the body in the stool. However, this is not a common occurrence. According to a case report by Jamil Shah and Abl Shahidullah, the lipoma can self-detach and be expelled from the rectum in very rare circumstances.
Such expulsion was to their knowledge, the first published case of spontaneous expulsion of an adenomatous polyp during defecation. The exact mechanism of self-detachment of the colorectal polyp is not well understood. Similar to lipomas, in large pedunculated polyps, the pedicle can become twisted and strangled, leading to necrosis and self-amputation of the polyp.
The report concluded that the spontaneous expulsion per rectum of such polyps is exceedingly rare. Such a patient should undergo colonoscopy to search for additional polyps as well as other gastrointestinal pathology.
REMEMBER THAT:
Most bowel polyps are discovered during a colonoscopy or other diagnostic tests, rather than being passed out in the stool. If you are concerned about bowel polyps or are experiencing any unusual symptoms, it is important to speak with a medical professional. They can provide a proper evaluation and recommend appropriate treatment if necessary.
