Table 1. Postoperative peritoneal adhesions (raw scores) assessed through a second-look laparoscopy performed 30 days after standardized bilateral tubal injury and excision of adjacent peritoneum of the pelvic sidewall to provoke adhesion formation.

PAI (Peritoneal Adhesion Index) is the sum of the raw scores in all regions (Adapted from Coccolini et al., 2013) [21]: 0 No adhesions; 1 Filmy adhesions, blunt dissection; 2 Strong adhesions, sharp dissection; 3 Very strong vascularized adhesions, sharp dissection, damage hardly preventable. Area scores (adhesion area / injured area ratio): 0 (no adhesion); 1 (≤25% of initial injured area); 2 (>25% and <50% of initial injured area); 3 (50% - 75% of initial injured area) or 4 (>75% of initial injured area) [13]. The excised area of the sidewall peritoneum adjacent to each uterine horn was considered as a reference injured area (about 8 x 10 cm). Sites with no adhesions in all ten animals (all scores = 0) were not included in this table. The animals were numbered in order according the time of the first surgery (injury).
