Rectal foreign bodies: case reports and a comprehensive review of the world's literature.

The surgical management of two patients presenting with incarcerated, apparently self-inserted foreign bodies is reported. The large volume of prior literature on this subject is reviewed, with tabulation of 182 previous cases by type and number of objects recovered and with a discussion of patients' age distribution, history, complications, and prognosis. Management problems addressed include history, differential diagnosis of reported pruritus ani, and handling of suspected assault. The variety of surgical techniques used to remove rectal foreign bodies transanally or after celiotomy is discussed. Vaginal foreign bodies and large bowel injuries due to fist fornication, colorectal instrumentation, pneumatic rupture, foreign body ingestion, impalement, and abdominal trauma are also discussed.
