title: The problem of the open safety pin.
abstract: The open safety pin lodged in the stomach or esophagus presents a challenge to surgical judgment and technical skill. Most foreign bodies causing trouble lodge in the esophagus. Once in the stomach, uneventful passage can be expected in 80 to 90% of cases. Active intervention is reserved for those where intestinal performation is likely or where there is failure to progress. We have used the fiberesophagoscope to remove three open safety pins from the stomachs of two patients whose symptoms and threat of perforation required intervention. The microbiopsy forceps was used successfully to retrieve the open pins,  but a newly developed grasping forceps for use with the fiberesophagoscope now provides a more secure hold on such foreign bodies. Rigid instruments retain their value for selected cases, but the flexible equipment now provides an important advance in the management of the open safety pin in the stomach.
