[Possibilities of tissue perfusion assessment in abdominal surgery: integration into the intraoperative system of safety control points]. / Vozmozhnosti otsenki perfuzii tkanei v abdominal'noi khirurgii: integratsiya v sistemu intraoperatsionnykh kontrol'nykh tochek bezopasnosti.

OBJECTIVE: To evaluate the possibility of integrating tissue perfusion assessment techniques (ICG perfusion and imaging photoplethysmography - iPPG) into the system of intraoperative control points of laparoscopic interventions with a reconstructive component. MATERIALS AND METHODS: Quantitative assessment of ICG fluorescence and iPPG were used during 8 laparoscopically assisted interventions: gastrectomy for gastric cancer (total - 2 and distal - 1) and colorectal resections (left-sided colorectal resections - 4 and right hemicolectomy - 1). RESULTS: Four stages are presented for the assessment of tissue perfusion: initial assessment, before intestine transection, before anastomosis formation, and evaluation of anastomosis. From the point of view of the significance of clinical decision-making, the «before intestine transection¼ stage is of great importance, due to the ease of transferring the resection level to the optimal tissue perfusion zone. CONCLUSION: Integration of tissue perfusion assessment techniques into the system of intraoperative checkpoints is possible and promising.
