Abstract

We confirmed in animal experiments that the Nd-YAG laser can be used to replace conventional surgical techniques for duodenal ulcer disease—lesser curve seromyotomy, as proposed by Taylor. The experiments suggest that the operative time may be halved using the laser. We confirmed that the ideal laser parameters for this technique were: wavelength 1319nm and power output 15 W, using a contact sapphire tip, with repeated pulses of 0.25 s. Histological studies were performed to show the effect of the laser on the stomach wall and on the vagus nerve. It was shown that the pH was elevated from 1.3 to 6.9 or even higher.

The first successful operation on man with this technique was performed in May 1989.
