Use of a Laser to Stop a Bleeding Ulcer ------------------------------------------------------------------------------ QUESTION: When my husband recently was hospitalized with a bleeding ulcer, our fine doctor saved him by using a scope and a laser gun to stop the bleeding, and my husband was able to come home in just a day or two. However, my son is skeptical, as he says that lasers are used to cut tissue, not to stop bleeding. He thinks I didn't understand the doctor's explanation. Can you explain what happened so my son won't think his mother is losing her grip? ------------------------------------------------------------------------------ ANSWER: I certainly can describe a procedure that seems to be the one your doctor used. Of course, we don't call it a "laser gun," but lasers can be used to stop bleeding in the stomach as well as replacing the scalpel for cutting in some circumstances. There are two main types of laser equipment currently available; the argon laser, and the Nd-YAG laser, which uses a garnet to generate the light beam. Though both types can be used, some statistics indicate that perhaps the YAG laser is the more effective in cases like these, and probably stops the bleeding by causing the muscles in the wall of the bleeding artery to contract and close the vessel, as well as by clotting the proteins found in the blood and tissues. Since the physician can see the bleeding vessel through his scope (endoscope), he can apply the laser beam directly to the spot that is hemorrhaging, stopping the flow of blood. Another procedure, using an electrocautery system, where electrical current is used to coagulate blood and tissue, is also available in several forms. In some cases reported, injections of liquids to sclerose (harden and close) the bleeding vessels have met with some success as well. If your son still doubts the truth of your report, he might call your physician directly and prove that Mom is still on the ball. ---------------- The material contained here is "FOR INFORMATION ONLY" and should not replace the counsel and advice of your personal physician.
