[The use of contact impulse-periodic YAG-ND laser in surgery of major duodenal papilla].
YAG-Nd impulse-periodic laser scalpel in elimination of major duodenal papilla stenosis was tested experimentally. The direct damaging influence of the laser was tested in acute experiments and the optimal power of irradiation (5 W) was chosen. The processes of regeneration of the wound inflicted by laser irradiation were tested in chronic experiments. It is shown, that regeneration was accompanied with minimal leucocyte infiltration and complete healing of the wound is achieved in 28 days.
