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 35.47.33 in females and 32.55.32 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 35.47.33 and 32.55.32 respectively, as this will help in assessing prognosis in patients with gallbladder diseases.

Research Objectives and Themes
The primary objective of this research is to evaluate and establish the gallbladder contraction indices in residents of Calabar using ultrasound, as there is a lack of localized documentation and prediction formulas. The study investigates the physiological motor function of the gallbladder and determines whether factors such as gender, age, height, or weight influence gallbladder volume and contractility.
- Evaluation of Gallbladder Contraction Indices (GBCI) in healthy adults.
- Assessment of the physiological impact of fatty meals on gallbladder emptying.
- Comparative analysis of gallbladder contractility between males and females.
- Analysis of the influence of demographic and anthropometric factors on gallbladder volume.
- Validation of ultrasound as a precise, non-invasive diagnostic tool for gallbladder motor function.
Excerpt from the Book
INTRODUCTION
The gallbladder is a pear-shaped distensible bag with a capacity of 30-50ml. It is located in the right upper quadrant of the abdomen in the gallbladder fossa along the visceral surface of the liver. It is measured about 8-10cm in length and 3-5cm in transverse diameter and helps in the digestion of fat (Keith et al, 2006).
The term “contracted gallbladder” refers to one that is smaller than normal. It occurs in two different situations. The first preceded by a meal or events that cause the muscles of gallbladder to contract, for example, ingestion of fat or injecting intravenously, a hormone that is responsible for causing the gallbladder to contract. In either case, the gallbladder empties, and becomes smaller, and is said to be contracted. The second situation is when the gallbladder is diseased, specifically, inflammation and becomes smaller than normal. The contraction of a gallbladder in such a situation is typically caused by scarring (due to presence of gallstones). Scarring cause the gallbladder no longer functions normally (Pallot et al., 2003).
Summary of Chapters
Introduction: Provides the anatomical background of the gallbladder and establishes the necessity of evaluating gallbladder contraction indices for clinical assessment of hepatobiliary health.
Materials and Methods: Details the prospective analytical study design, the participant selection criteria, and the equipment used for data collection, including the specific ultrasound system.
Results: Presents the findings of the sonographic scans and the statistical analysis regarding gallbladder contraction indices in relation to age, height, weight, and gender.
Discussion: Interprets the findings by comparing them with existing literature and explores the physiological reasons for variations in contraction indices between genders and age groups.
Conclusion: Summarizes the study's discovery that females in the study area exhibit higher gallbladder contraction indices than males, suggesting a potentially higher predisposition to gallstone formation.

Frequently Asked Questions
What is the core subject of this research?
The research focuses on the assessment of gallbladder contraction indices in healthy adults living in the Calabar metropolis using real-time ultrasound technology.
What are the primary thematic areas covered?
The study covers gallbladder anatomy, the physiology of bile digestion, the use of ultrasound in diagnostic imaging, and the analysis of factors influencing gallbladder motility.
What is the main research objective?
The objective is to establish baseline values for gallbladder contraction indices in the local population to assist clinicians in assessing gallbladder motor function and potential disease prognoses.
Which scientific method was employed?
The study used a prospective analytical design, employing real-time ultrasound imaging to measure gallbladder volume pre- and post-ingestion of a fatty meal stimulant (milk).
What is addressed in the main body of the work?
The main body covers the methodology of sonographic measurement, the collection of data from 70 participants, and the subsequent statistical analysis correlating gallbladder indices with sex, age, height, and weight.
Which keywords best characterize this study?
Key terms include gallbladder, ultrasound scan, contraction index, Calabar metropolis, gallbladder volume, hepatobiliary health, and motor function.
Why was dry peak milk used as a stimulant?
Dry milk served as a cost-effective and reliable physiological stimulant to induce gallbladder contraction, as it contains enough fat to trigger the release of bile without the need for expensive clinical agents.
How were the ultrasound measurements standardized?
The study utilized the ellipsoid formula to calculate gallbladder volume and conducted scans in a supine position to ensure participant comfort and consistent imaging results during deep inspiration.
