Laser-assisted removal of a foreign body from the colon.

An 81-year-old woman underwent a colonoscopy because of a sigmoiditis poorly responding to conservative therapy. A rod-shaped foreign body found in the sigma proved impossible to remove conventionally. Irradiation with a low laser energy caused the foreign body to break apart, after which its extraction was straightforward. The further clinical course was uncomplicated. In this case a partial sigmoidectomy would have been indicated had the laser-supported extraction not been successful. The authors suggest that a similar procedure could be helpful in the management of foreign bodies in the esophagus.
