title: Grades of gallbladder diseases using gallbladder contraction index: a pilot study.
abstract: The aim of this study was to develop a pilot model for the assessment of the severity of gallbladder diseases based on gallbladder contraction index, clinical and sonographic appearances of the gallbladder. The gallbladder contraction index (GBCI) was obtained as the average of the first ten and the first 20 minutes contraction indices. A range of 5% to 77% previously obtained in normal subjects was adopted in this study. Gallbladder contraction index in combination with other variables: sonographic appearances and clinical presentations were used for the grading of gallbladder diseases in the present study. This pilot model may have a good diagnostic performance but a clinical prospective evaluation is needed to confirm its actual value.
