Abstract: Gastrointestinal tract divide into mouth, pharynx, esophagus, stomach, and intestines. The intestine is divided into the small intestine and the large intestine. The small intestine extends from the pylorus to the ileocecal junction. The large intestine is about 1.5 m long and extends from the cecum in the right iliac fossa to the anus in the perineum. The frequent locations of impaction of sharp foreign body are duodenal loop, duodenojejunal flexure (Angle of Treitz), appendix vermi- form and terminal ileum. Esophagus is a muscular and mucosal tubular organ with 4 physiological narrowing’s that are preferred sites for the retention of foreign bodies accidentally or deliberately ingested. The latter form is frequent in people with mental disorders and prisoners. The aim of this case report is to draw the attention of the medical profession (ENT, Surgeon, Gastroenterologist, physician, etc.) that not all foreign bodies in adults have suicidal intent or are linked to people with mental disorders or prisoners. This case describes an incident in which a young man deliberately swallowed a key to hide evidence of theft. This is a unique case in the literature of deliberate inges- tion in mentally healthy people and not part of the prison population. In the presence of intention- ally and/or accidental foreign bodies ingested in adults, it is necessary to discard mental disorders or emotional or social factors. Due to the characteristics of the object and the presence of few symp- toms, except hiccups, it was not necessary to subject the patient to any surgical intervention. Re- member that some foreign bodies may be passing spontaneously in the family environment and without hospital intervention.

Esophagus it is the tubular part of the digestive tract that joins the pharynx to the stomach, crossing three regions in its path: neck, chest, and abdomen, passing through the diaphragm muscle through a hole, the esophageal hiatus. The stomach is the widest and most distensible part of the digestive tract, located between the esophagus and duodenum [1]. The intestine is divided into the small intestine and the large intestine. The small intestine extends from the pylorus to the ileocecal junc- tion. The large intestine extends from the cecum in the right iliac fossa to the anus in the perineum and divided into four parts: Cecum and appendix vermiform, Colon, Rectum and Anal canal [1].
