Percutaneous retrieval of a surgical laparotomy sponge from the peritoneal cavity.

Percutaneous retrieval of an extravascular foreign body is an uncommon procedure. This report describes the successful retrieval of a 46 x 46-cm laparotomy sponge from the peritoneal cavity using a Nitinol Gooseneck Snare system. This technique can eliminate the need for exploratory surgery and may be particularly useful in poor operative candidates.
