Predictive value of platelet-related hematological markers in indicating the outcomes after laparoscopic intraperitoneal onlay mesh repair (IPOM).

Abstract

<h4>Background</h4>The predictive value of hematological markers in the outcomes after laparoscopic intraperitoneal onlay mesh repair (IPOM) remains to be investigated. We aim to evaluate the role of platelet-related parameters after laparoscopic IPOM in patients with incisional hernias.<h4>Methods</h4>The data of 95 patients who underwent laparoscopic IPOM for appendicectomy-related incisional hernias were retrospectively analyzed. The complete blood count analyses were measured preoperatively, and the outcomes were obtained from hospital records and follow-up calls to patients. Platelet-multiple-lymphocyte index (PLM), neutrophil-leukocyte ratio (NLR), lymphocyte-monocyte ratio (LMR), platelet-lymphocyte ratio (PLR) and systemic immune-inflammation index (SII) values were calculated. The patients were grouped based on the recurrence and the postoperative complications after surgery.<h4>Results</h4>Using cutoff values acquired by the Youden Index, we found platelet levels < 212.0 × 1000/μl, NLR > 2.33, LMR < 3.17, and PLM < 365.5 were revealed to be statistically significant in the recurrence of hernias based on univariant or multivariant analysis (p =  < 0.05). We further divided the patients into two groups based on the cutoff value of PLM and found that a PLM value < 365.5 was significantly associated with the recurrence of incisional hernia (p = 0.018), the occurrence of postoperative seroma (p = 0.044), and there is a tendency that patients with PLM < 365.5 may suffer from other postoperative complications such as cardiopathy, respiratory infection, and hypoproteinemia (p = 0.089).<h4>Conclusion</h4>The preoperative hematological values, especially PLM, may indicate the outcomes in incisional hernias after laparoscopic IPOM.
