[Basic data in the application of a new intensity distribution in laser treatment of the upper digestive tract].
A new pattern of intensity distribution of laser beam, in the shape of a "topfkuchen" was found to be satisfactory in avoiding perforation when applied to the gastrointestinal tract. Basic data of the optical and thermophysical properties of the different layers in the stomach of pigs were obtained. Using our distribution pattern of intensity we could see a uniform, superficial zone of coagulation. There were no perforations even after the intact mucosa of the stomach was irradiated by 175 Watts for 2 seconds.
