The use of lasers in colorectal cancer.
The potential addition of lasers to the armamentarium of physicians treating advanced colorectal cancer is welcome because of the morbidity associated with the disease and because of the limitations of standard treatments for some of the problems related to this common disease. However, laser treatment cannot be regarded yet as a standard modality. Questions still remain regarding the efficacy of these treatments in relieving the most troublesome symptoms of tenesmus and urgency, although bleeding and mucous discharge appear to be well controlled. Additional questions remain regarding expense and the relative benefits of lasers versus electrocoagulation (much cheaper) for rectal cancers. Other concerns relate to the learning curve involved with lasers, particularly for decompression of colonic obstructions, and efficacy compared to pneumatic dilatation.
