Abstract

The aim of the research is to evaluate the condition of blood flow in the area of digestive anastomosis in the early and delayed postoperative period in an experiment. The experiment included 30 sexually mature laboratory rabbits-males of the breed Soviet Chinchilla. The animals were done laparotomy, enterotomy, followed by the imposition of a digestive single-row nodular anastomosis "edge to edge", then the evaluation of local blood flow condition in the zone of digestive anastomosis was performed in the early (3 days) and delayed (7, 14 days) postoperative period using the method of Laser Doppler Flowmetry (LDF). The data received demonstrated a decrease of local blood flow in the early postoperative period in the area of digestive anastomosis, that forms the most vulnerable period for the development of its insufficiency. In the delayed postoperative period, there is an improvement in the indicators of local blood flow in the anastomosis zone, with an approximation of their values to the condition of the intact intestinal tract.
