Most objects that are swallowed will, if they have passed the pharynx, pass all the way through the gastrointestinal tract unaided. However, sometimes an object becomes arrested (usually in the terminal ileum or the rectum) or a sharp object penetrates the bowel wall. If the<unk> <unk>  causes problems like pain, vomiting or bleeding it must be removed. Swallowed batteries can be associated with additional damage, with mercury poisoning (from mercury batteries) and lead poisoning (from lead batteries) presenting important risks. While swallowed coins typically traverse the<unk>  tract without further incident, care must be taken to monitor patients, as reaction of the metals in the coin with gastric acid and other digestive juices may produce various toxic compounds if the coin remains within the<unk>  tract for a prolonged period of time. Endoscopic<unk> <unk>  retrieval is the first-line treatment for removal of a<unk> <unk>  from the<unk>  tract. Glucagon has been used to treat esophageal<unk>  bodies, with the intent that it relaxes the smooth muscle of the lower esophageal spincter to allow the<unk> <unk>  to pass into the stomach. However, evidence does not support a benefit of treatment with glucagon, and its use may result in side effects.
