A Unique Case of Foreign Body Acquired by Stabbing and Retained for 7 Years in the Sigmoid Colon

The ingestion of foreign bodies is a common cause for presentation in the emergency department by pediatric, adult, or elderly psychiatric patients. Swallowed foreign bodies sometimes represent a great challenge for surgeons due to the obstruction or perforation of the digestive tube's upper or lower segments. Occasionally, the foreign bodies detected in the lower parts of the digestive tube (colon and rectum) could be introduced through the anal route with the risk of perforation of the rectum or sigmoid colon. In this report, we describe a unique case of a foreign body located in the sigmoid colon, where it arrived due to backstabbing and was retained for 7 years without acute symptoms. The 43-year-old male patient came to the emergency department with pain in the left iliac fossa. Before his presentation, a computerized tomography (CT) scan examination had suggested a foreign body. A surgical approach was decided. The surgery started as an exploratory laparoscopy and was converted to a xiphoid-pubic incision to extract the foreign body (a piece of glass about 8 cm long) through a sigmoid colotomy followed by a double-layer sigmoidorrhaphy. The postoperative evolution of the patient was uneventful. As far as we know, this is the first case of a patient with a foreign glass body positioned in the sigmoid colon that got there by stabbing and not by ingestion or introduced per anum. In conclusion, we suggest that aggressive behavior and abdominal wall penetration by different sharp objects should be considered when foreign bodies are detected in the abdomen.
