Thankfully uncommon a gossypiboma describes when a foreign object, usually of fabric/textile origin, in left within the body following a surgical procedure. The name is derived from the gossypium(Latin for cotton) and oma (Latin for a tumour or growth).
It is typically due to a swab or surgical pack being left behind - the latter in this case.
Frequently a collection develops around the foreign body. In addition in this case a small bowel obstruction occurred.
Theatre do 'swab count' at the end of procedures, but as this case demonstrates it is not always fullproof.
This case was proven at surgery.
