Methods: The data of 200 patients who underwent surgery for incarcerated hernia were retrospectively analysed. The patients were grouped into three groups; Group 1; only surgical reduction and hernia repair, Group 2; small bowel resection and Group 3; omentum resection. Age, gender, hernia type, the presence of radiological bowel obstruction and preoperative complete blood count data were obtained. Neutrophil-leukocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelet-lymphocyte ratio (PLR), haematological inflammatory index (HII) and systemic immune-inflammation index (SII) values were calculated. Results: The study was consisted of; Group 1: 119 patients (59.5%), Group 2: 46 patients (23%) and Group 3: 35 patients (17.5%). Advanced age (p = 0.001), female gender (p = 0.036), incisional hernias (p = < 0.001) and the presence of bowel obstruction (p = < 0.001) were found to be statistically significant in terms of strangulation. NLR, PLR and SII values were significantly higher in Group 2 compared to Group 1, and PLR values were significantly higher in Group 2 compared with Group 3 (p < 0.05). Conclusion: The preoperative elevated NLR, PLR and SII values may indicate strangulation and possible intestinal resection, in incarcerated abdominal wall hernias.
