Rectal foreign body

Case contributed by A.Prof Frank Gaillard

Presentation

"Oh no, I don't want you to take it out; I just need you to put in some batteries."

Patient Data

Age: Adult
Gender: Male

Abdominal x-ray

Modality: X-ray

X-ray of the abdomen demonstrates an electronic device in the distal sigmoid colon. There is some distension of the sigmoid proximal to it. No convincing evidence of free gas. The tip of the radiolucent covering reaches the top of L3 (note the sacralised L5 vertebra). 

Annotated

Modality: Annotated image

The top of the device (green) is located at the top of L3. The motor (blue) with off-set weight (red) are connected to the battery housing (yellow) - devoid of batteries - by two wires. The speed of the motor (and thus the frequency of the vibrations) are controlled by a switch (orange). 

Case Discussion

Although these are referred to as rectal foreign objects, they often migrate proximally into the distal colon.
