- Abstract
Aim: Acute appendicitis (AA) is the most common cause of acute abdominal pain and emergency surgery worldwide. This study aimed to evaluate the effect of the preoperative platelet-to-lymphocyte ratio (PLR) on the conversion from laparoscopic to open appendectomy. Method: This study retrospectively evaluated patients with AA who were hospitalized in the general surgery clinic between September 2015 and September 2020. The study included patients who underwent laparoscopic appendectomy under the same surgical team and those who required conversion to open surgery. Results: During the study period, a total of 389 patients were followed and treated for AA in our clinic. Laparoscopy was initiated in 117 patients. While laparoscopic exploration alone was performed in four patients, conversion was done in 13 patients (11%), and laparoscopy was successfully completed in 100 patients (89%). Although increased preoperative white blood cell count was not a predictive factor for the conversion (p= 0.605), sex, age, elevated C-reactive protein levels, increased preoperative appendix diameter, higher body mass index, complicated AA, and increased preoperative PLR and neutrophil-to-lymphocyte ratio values were predictive factors affecting the conversion to open appendectomy (p values were 0.042, <0.001, 0.02, 0.014, 0.008, 0.011, <0.001, and 0.001, respectively). The sensitivity and specificity of PLR values for determining the conversion in the preoperative period were 76.9% and 84%, respectively, with a cutoff value of =190.56 (area under the curve: 0.853; confidence interval: 0.728-0.928). Conclusion: Results showed that the preoperative PLR values, when evaluated together with other predictive parameters, are predictive factors for patients who will undergo laparoscopic appendectomy.
