Comparison of heater probe and YAG laser in endoscopic treatment of major bleeding from peptic ulcers.

In our experience using the YAG laser and the heater probe in endoscopic treatment of major hemorrhage from peptic ulcers, ultimate hemostatic success was achieved in 19 of 20 (95%) ulcers treated with the heater probe, versus 24 of 35 (69%) YAG laser-treated ulcers (p less than 0.05). The heater probe was considerably faster, more convenient to use, and safer than YAG laser. We presently consider the heater probe to be the preferred endoscopic hemostatic device.
