Objective:
To determine whether there is a relationship between complete blood count parameters at adnexal torsion and to investigate the clinical utility of these parameters in preoperative diagnosis.
Methods:
The retrospective, case-control study was conducted at a tertiary care hospital in Turkey and comprised data of patients who underwent adnexal torsion surgery from 2007 to 2017. Medical records of healthy controls who underwent various gynaecological surgeries during the period were used as the control group. Demographic characteristics and preoperative complete blood count parameters were retrieved from the medical records, and factors influencing adnexal torsion diagnosis were evaluated. Data was analysed using SPSS 21.
Results:
Of the 296 subjects, 73(24.7%) were adnexal torsion cases and 223(75.3%) were controls. Demographic characteristics did not differ between the groups (p>0.05). Leukocytosis was present in 38(52%) cases. Mean white blood cell, neutrophil, and platelet counts and neutrophil-to-lymphocyte and platelet-to-lymphocyte ratios were significantly higher, and mean platelet volume was significantly lower in the cases compared to controls (p<0.05). Logistic regression analysis identified an independent association between a low mean platelet volume and adnexal torsion (p<0.05). The optimal cutoff value was 10.35fL, with 77.4% sensitivity and 74.2% specificity.
Conclusions:
There was found to be a significant relationship between adnexal torsion and certain parameters of the complete blood count. Low mean platelet volume could be considered a useful additional tool for the preoperative diagnosis.
