[State of microcirculation channel in the area of laser "welded" anastomosis of the small intestine]. / Sostoianie mikrotsirkuliatornogo rusla v oblasti lazernogo "svarnogo" tonkokishechnogo anastomoza.

ABSTRACT

Experiments were conducted with CO2 and AIG laser on neodymium to study the condition of microcirculation and the degree of its disturbance in the wall of the small intestine in formation of a laser "welded" entero-enteral and termino-terminal anastomosis. The microcirculatory disorders and their extent were found to be directly dependent on the degree of the thermal effect and the width of the coagulation zone in the region of the suture. The results of the experiment confirmed that the suggested powers of the laser effect on the intestinal wall were optimal.
