Laser: gastrointestinal applications.
Although still considered an investigational medical device, and therefore restricted to use in clinical trials, the Nd:YAG laser has become increasingly available in the United States. The laser has been successfully used in the treatment of acute and chronic gastrointestinal bleeding, and for the palliation or ablation of intestinal tract neoplasms. Ongoing trials are needed to determine the cost-effectiveness and side-effect liability as compared to more conventional medical and surgical therapy.
