Doctor's Notes on Foreign Body in Rectum
The rectum is the end segment of the large intestine (the bowel) just inside the anus. Any type of object inserted into the anus may become stuck in the rectum. In some cases, a foreign body is swallowed and passes through the digestive tract, eventually getting stuck in the rectum. Foreign bodies can be anything from bottles, candles, fruits and vegetables, medical devices (a broken rectal thermometer or broken enema catheter tip), or sex toys such as vibrators or dildos.
Most people with an object in their rectum may have no signs or symptoms, which can make a diagnosis difficult, especially in children and in psychiatric patients. When treatment is delayed, complications may arise. Symptoms of complications of a foreign body in the rectum include
What Is the Treatment for Foreign Body in Rectum?
Foreign bodies in the rectum that do not come out on their own must be removed by a doctor. Depending on the type of object, the location (depth) within the rectum or colon, or the possibility of complications due to the object, some objects can be removed safely in the emergency department. Some objects may be too far inside the rectum or there may be evidence of damage to the intestine wall. In these cases, the patient may need to be sedated and a surgical procedure may be necessary.
Procedures used to remove rectal foreign objects include:
- Small objects deemed harmless may be left to pass in the stool naturally or with the help of laxatives
- Lubricating the rectum and manually grasping the object
- Using an anoscope (tool for opening the rectum to look inside) to further open the rectum so the object may be grasped with surgical tools
- Passing a balloon catheter (such as a Foley urinary catheter) past the object and then gliding the object out
- Using a flexible sigmoidoscope or colonoscope to retrieve the object and assess for damage to the colon
- Bowel surgery under general anesthesia, especially if there is a high suspicion of damage or perforation of the bowel due to the object

Bowel (Intestinal) ObstructionA bowel (intestinal obstruction) is a partial or complete obstruction or blockage of the small or large intestines (ascending and descending colon). Early signs and symptoms of a partial, small, or large intestinal obstruction include abdominal pain or distention, nausea, dehydration, blood in the stool, fever, rapid heart rate, inability to pass gas or have a bowel movement, and narrow stools. Causes of bowel obstruction in teens and adults include abdominal tumors, Crohn’s disease, and trapped gallstones. Causes in children include birth defects and intussusception. Causes in the elderly include colon cancer and gallstone ileus. Common types of intestinal obstruction include colon cancer, diverticulitis, and diabetes.
Colonoscopy ProcedureColonoscopy is a procedure used to view the inside of the colon. Reasons for colonoscopy is to detect or diagnose diseases of the colon, for example, Crohn’s disease, ulcerative colitis, other types of colitis, colon polyps, colon cancer, diverticulitis, and other bowel and rectal diseases. Risks for colonoscopy include colon perforation, infection, or bleeding.
CT Scan vs. ColonoscopyCT scans utilize X-rays to form images of organs and tissues inside the body (for example, abdominal organs, brain, chest, lungs, heart) while colonoscopy is a procedure that can visualize only the inside surface of the colon. CT scans use radiation (X-rays) to form images while colonoscopy uses a flexible instrument equipped with a light and camera to form images, and it may be used to collect biopsy of colon tissues and/or polyp removal.
Eye Foreign BodyA foreign body in the eye can range from nothing serious to a serious condition that requires immediate treatment. A foreign body in the eye may cause burning, irritation, tearing, and redness. Treatment depends on the extent of the eye injury.
