OBJECTIVE: Diverticulitis is a health problem that has increased in frequency recently. It has a wide spectrum from simple inflammation to fecal peritonitis, sepsis and even mortality. Thus, it is important to predict diverticulitis, especially recurrent diverticulitis, and take measures to prevent it. In this study, we investigated the predictive value of the PLT/MPV ratio, which is an inflammation marker in predicting the recurrence of diverticulitis disease.

PATIENTS AND METHODS: In this study, 132 patients diagnosed with diverticulitis were analyzed retrospectively. Patients’ gender, age, localization of diverticulitis, number of diverticula in computed tomography (CT), hospitalization status, length of hospitalization, control colonoscopies, polyps’ number and localizations in colonoscopies, presence of malignancy, need for surgery, and recurrences were not reported. White blood cell (WBC), Neutrophil (NE), Lymphocyte (LY), Hemoglobin (Hb), PLT, MPV, Albumin, Creatine Kinase (CK) and C-reactive protein (CRP) levels were examined. The patients were divided into two groups as those who did not relapse concerning diverticulitis and those who did, and statistical analysis was performed between the two groups about related parameters.

RESULTS: Among all patients, recurrence was seen in 11 (10.1%) patients. The patients were divided into two groups according to their recurrence status and statistical significance was sought between the data. The calculated PLT/MPV ratio of patients who did not relapse was 25.61±8.05 and 34.98±11.37 for those who had a relapse (p=0.006). The sensitivity for MPV was 81.8%, a specificity of 57.1% and a cut-off of 9.85. The cut-off value for PLT was 207.5 with 100% sensitivity and 33.7% specificity. A cut-off value of 25.11 was found for PLT/MPV with 100% sensitivity and 49% specificity.

CONCLUSIONS: PLT/MPV ratio was significantly higher in relapsed cases. Since it is easily accessible and inexpensive, it will guide physicians for diagnosis concerning early detection of relapse cases and initiation of appropriate treatment
