Assessment of Gall Bladder Contraction Indices in Calabar Using Ultrasound (PDF)

Academic Paper from the year 2021 in the subject Medicine - Other, University of Calabar (University of Calabar, Nigeria), language: English, abstract: Gallbladder contraction index is an indication of gallbladder motor function which affected by some gallbladder disease. Ultrasound was used because of its high sensitivity in the detection of gallbladder dimension, real time character, speed and portability. It is non-ionizing and records the shape, nature and thickness of gallbladder contraction indices in health adults in Calabar using ultrasound, in order to help in the assessment of gallbladder disease. Measurement of the length, width and height of gallbladder were obtained from 70 normal subjects (40 males and 30 females) in Calabar who met the inclusion criteria using real time ultrasound between August and October, 2015. The gallbladder volume was calculated using ellipsoid formula. And the gallbladder contraction was physiologically stimulated by a fatty meal. The gallbladder contraction index (GBCI) was taken at 5th, 10th, 20th, 30th, 40th and 50th minute following the ingestion of a liquid milk. The gallbladder contraction index was obtained from the 70 subjects, and the mean of the two values was adopted as the actual GBCI. The results show that the mean GBCI (¿SD) in Calabar metropolis was 35.4¿7.33 in females and 32.5¿5.32 in males. There was no significant difference existing between gallbladder contraction in males and females (P<0.05). Age, height and weight show no effect on gallbladder volume (GBV) in all the subjects studied. But the gallbladder contractility in this study was increasing in females than in males. Therefore, the gallbladder contraction indices of subjects in Calabar metropolis has a mean of 35.4¿7.33 and 32.5¿5.32 respectively, as this will help in assessing prognosis in patients with gallbladder diseases.
