Sonographically determined clues to the symptomatic or silent cholelithiasis

Area of Science:

• Gastroenterology
• Radiology
• Medical Imaging

Background:

• Gallstones (cholelithiasis) can be symptomatic or asymptomatic.
• Gallbladder contractility plays a role in gallstone disease, but its association with symptoms requires further investigation.

Purpose of the Study:

• To investigate the association between sonographically determined gallbladder contractility and the symptomatic or silent nature of gallstones.
• To compare gallbladder contractility in patients with symptomatic gallstones, asymptomatic gallstones, and healthy controls.

Main Methods:

• A comparative, cross-sectional study involving adult gallstone patients and age/gender-matched controls.
• Ultrasound assessments of gallbladder wall thickness, volume, and ejection fraction before and after a standardized fatty meal.
• Analysis of demographic data, risk factors, and gallstone characteristics using statistical tests (Pearson Chi-square, One-way ANOVA).

Main Results:

• Gallbladder contractility, assessed by ejection fraction and volume changes, was significantly reduced in symptomatic gallstone patients compared to controls and asymptomatic groups (p < .001).
• Factors associated with symptomatic gallstones included multiparity, female gender, age < 50 years, impacted calculi, multiple calculi, and calculi size (≥5mm).

Conclusions:

• Sluggish gallbladder emptying is significantly associated with symptomatic cholelithiasis.
• Age, gender, stone impaction, number, and size are crucial factors in gallstone symptom development and influence management decisions.
