Introduction . Postoperative peritoneal adhesion remains a common complication. The lack of uniform, pathogenetically justified scoring scales that consider the timing of the experiment hinders the comparability of results. Aim . To develop a universal scoring scale for the adhesive process based on an analysis of existing scales.Materials and methods. Eight scales (Mazuji, Leach, Atta, adhe/ADHE, Moreno, Binda, Shurygina et al., Akentyeva et al.) were analyzed. Criteria included vascularization, ability to separate, macroscopic structure, area, number, length, bowel deformation, and adhesion type. Results (proposed scale) . A scale for the early period (days 3–5) includes fibrin deposits, peritoneal layer involvement, and affected area (%). For the late period (≥14 days), criteria include structure (membranous/loose/dense), separation ability (traction/blunt/sharp), area, and histological type (membranous/stringy). Conclusion . The proposed scoring scale standardizes adhesion assessment in experiments, accounts for pathogenesis and timing, and is applicable to any laboratory animal.
