[Possibilities of tissue perfusion assessment in abdominal surgery: integration into the intraoperative system of safety control points].

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 transection» 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.
