foreign body. By mouth The other way for a foreign body to travel through the digestive system (after oral intake and passage through the entire intestines) happens very often, but is only rarely medically relevant. Other constrictions, such as the esophagus, cardia, pylorus or ileocecal valve tend to cause issues with other organs, provided a foreign body is large enough to be an issue. Some foreign bodies may still pass those narrows and may cause medically relevant issues, i.e. toothpicks and bones. Bones especially, i.e. from chickens, cause about two thirds of all intestinal perforations. Plant-based food, especially seeds like popcorn, watermelon, sunflower and pumpkin seed, may clump together inside the lower intestines to form bezoars. Those may grow too big for normal anal passage, thus becoming clinically relevant. This kind of rectal foreign body happens chiefly in children, especially in Northern Africa and the Middle East, where those seeds form an elemental part of the diet. In very rare cases, seeds inside a bezoar may germinate inside the lower intestines or the rectum, causing a blockade. Objects Type and size of the foreign rectal bodies are diverse and may exceed the anatomical-physiological imagination. Objects documented in literature include: Razor, screw, screwdriver, small rolled tool bag (15×12 cm, including tools 620 g), hairpin, milk can opener, drill bit Short staffs, such as a 27 cm long chair leg, a 19 cm long spade handle and a broken off broom handle, extension parts for a vacuum cleaner Containers, sometimes exceeding 0.5 L in volume, e.g. sparkling wine bottles, bottles of Coca-Cola, jam pots, small beer glasses, cups Spray can, light bulb, vacuum tube, candle WWII artillery shell requiring attention from a bomb squad Table tennis ball, Boccia ball Ammunition, firecracker Vibrator, rubber rod, dildo a toy car spectacles, a suitcase key, a tobacco pouch and a magazine at the same time plastic tooth brush case Not all objects are solid. In 1987, a case was documented of a patient who administered a cement enema. After it solidified and impacted, the resulting block had to be surgically extracted. Another extreme case occurred in November 1953. A depressed man inserted a 15 cm long cardboard tube into his rectum and tossed a lighted firecracker into the tube's opening, resulting in a large hole in his rectum. Diagnosis Many patients feel ashamed during the anamnesis and provide information only reluctantly. This may lead to
