BackgroundThis study aimed to evaluate the diagnostic value of gray-scale and power Doppler sonography for acute cholecystitis and show a correlation between sonographic and intraoperative findings, quantitively.MethodsForty chronic and forty acute cholecystitis patients were examined. Early laparoscopic cholecystectomy was performed for acute cholecystitis. Demographic characteristics, sonographic findings, and adhesion scores were analyzed. Data were collected prospectively (clinicaltrials.gov: NCT02156947).ResultsWall thickness (≥3 mm) and vascularity increased in acute cholecystitis (p<0.01 and <0.01). Vascularity was found to be moderately correlated with adhesion (p<0.01, r=0.59) but it did not affect the difficulty of the operation by means of perforation, conversion rate, and operation time. In addition, wall thickness did not correlate with adhesion formation (p=0.36). Sensitivity and specifity of wall thickness and vascularity were found to be 96.9%, 72.7%, and 68%, 87.2%, respectively. When both diagnostic measurements were taken into account, sensitivity was calculated 69.7% and specificity reached up to 97.6%.ConclusionVascularity correlated with adhesion but failed to predict operation difficulty. Specificity of gray-scale sonography could be improved with power Doppler examination; however, desired diagnostic accuracy could not be obtained with only quantitive measurements of sonography.
