TY - CHAP M1 - Book, Section TI - Chapter 72. Rectal Foreign Body Extraction A1 - Reichman, Eric F. PY - 2013 T2 - Emergency Medicine Procedures, 2e AB - Foreign bodies within the rectum are the result of an ingestion from above or are placed into the anus from below.1 Fortunately, the majority of items ingested from above that pass the pylorus and ileocecal valve also pass the anal sphincter. The most frequent types of items found in the anus from above are undigested fish or chicken bones. Foreign bodies that are placed into the rectum from the anus are placed iatrogenically (e.g., enema tips and thermometers), inserted by the patient in an attempt to remove impacted stool, inserted by the patient or their partner as a form of anorectal auto-eroticism, forcibly placed in the anus during a rape, or placed in the rectum to smuggle objects across a border illegally.
