Mean Platelet Volume/Platelet Count Ratio: A New Diagnostic Parameter for Necrosis in Adhesive Small Bowel Obstruction—A Retrospective Cohort Study

Abstract

Abdominal adhesions are still one of the most common causes of intestinal obstruction. A major challenge in adhesive small bowel obstruction (SBO) management is to detect ischemia as early as possible to avoid necrosis and resection. Elevated mean platelet volume and decreased platelet count have been associated with worse disease course for various ischemic diseases in many clinical studies. The objective of the current study was to evaluate the predictive value of the mean platelet volume/platelet count ratio for patients with small bowel obstruction. Data for patients with adhesive small bowel obstruction, admitted to the general surgery department of Dicle University Hospital between November 2010 and March 2014, were reviewed retrospectively. Mean platelet volume (MPV)/platelet count (PC) ratio values, demographic data, vital signs, and laboratory blood test results of the patients were analyzed. Mean platelet volume/platelet count ratio was higher in bowel necrosis group, while there were no differences between the groups in terms of mean platelet volume values. Mean platelet volume and mean platelet volume/platelet count ratio was higher in patients who underwent surgical treatment. The cutoff value with the highest sensitivity and specificity for MPV/PC ratio was 0.02855 (sensitivity 68%, specificity 65%) for predicting bowel necrosis in patients with adhesive SBO. Mean platelet volume/platelet count ratio is associated with the failure of the conservative management and the presence of bowel necrosis in patients with adhesive small bowel obstruction.
