Summary
Gallstones impair gallbladder motor function and bile flow dynamics, even in asymptomatic individuals. Quantitative scintigraphy revealed decreased gallbladder ejection fraction and prolonged emptying times in patients with gallstones.
Area of Science:
- Gastroenterology
- Hepatology
- Nuclear Medicine
Background:
- Gallstones are common, often asymptomatic.
- Gallbladder motor function and bile flow are crucial for digestive health.
Purpose of the Study:
- To assess the impact of asymptomatic gallstones on gallbladder motor function.
- To evaluate alterations in bile flow dynamics in patients with gallstones.
Main Methods:
- Quantitative hepatobiliary scintigraphy used in 24 asymptomatic gallstone patients and 20 healthy controls.
- Key parameters measured: gallbladder ejection fraction (GBEF), gallbladder visualization time (GBVT), gallbladder time to peak activity (GBT(max)), gallbladder half emptying time (GBT(1/2)), and transit time of bile to duodenum (TTBD).
Main Results:
- Significant differences in gallbladder function parameters (GBEF, GBVT, GBT(max), GBT(1/2)) between patients and controls.
- Patients showed decreased GBEF and prolonged GBVT, GBT(max), and GBT(1/2).
- No significant difference in transit time of bile to the duodenum (TTBD) was observed.
Conclusions:
- Asymptomatic gallstones can lead to impaired gallbladder filling and emptying.
- Motor dysfunction of the gallbladder may be an early indicator of gallstone disease, even without clinical symptoms.

01:17Gallbladder
The gallbladder is a small, pear-shaped organ that plays a crucial role in our digestive system. Measuring about 10 cm in length, it is comparable in size to a kiwi fruit and is located in a hollow area on the lower surface of the liver. The gallbladder's primary function is to store and concentrate bile, a fluid produced by the liver that aids in digestion.
The gallbladder's anatomy consists of three regions: the fundus, body, and neck. Extending from the neck, the cystic duct joins the common...

01:20Cholecystitis
Cholecystitis is inflammation of the gallbladder, most commonly caused by obstruction of the cystic duct. This blockage prevents bile from draining, leading to gallbladder distension, inflammation, and potentially serious complications. This condition may present acutely or chronically and can happen with or without gallstones.EtiologyAbout 95% of cholecystitis cases are calculous, caused by gallstones blocking the cystic duct, leading to bile accumulation and inflammation of the gallbladder...
01:19Bile
Bile is a crucial bodily fluid, characterized by its yellow-green color and alkaline nature. Produced in the liver, it is transported through the common hepatic duct into either the cystic duct, leading to the gallbladder, or directly into the common bile duct. The flow of bile is regulated by the sphincter of Oddi located at the entrance of the duodenum. When this sphincter is closed, bile is redirected to the gallbladder for storage and concentration.

01:26Diseases of the Liver and Gallbladder
Liver and gallbladder diseases are a significant health concern, with prominent conditions including cirrhosis, hepatitis, non-alcoholic fatty liver disease (NAFLD), and gallstones. Jaundice is a common manifestation of liver and biliary disease.
Cirrhosis is characterized by the scarring of hepatic lobules in the liver, which are replaced by fibrous tissue, affecting the liver's normal functioning. NAFLD, on the other hand, is caused by an excessive build-up of fat in the liver, not related to...

01:16Hepatic Drug Excretion: Influencing Factors
The biliary system of the liver, crucial for bile secretion and drug excretion, comprises intrahepatic bile ducts that merge to form the common hepatic duct. This duct, carrying hepatic bile, combines with the cystic duct, draining the gallbladder and forming the common bile duct, which empties into the duodenum. Bile, produced by hepatic cells lining the bile canaliculi, is composed primarily of water, bile salts, pigments, electrolytes, and lesser amounts of cholesterol and fatty acids. Bile...
01:17Chronic Bowel Disorders: Introduction
Chronic bowel diseases are a group of long-term conditions affecting the digestive tract, characterized by inflammation and damage to the gut lining. These conditions primarily include irritable bowel syndrome and inflammatory bowel disease.
Irritable Bowel Syndrome (IBS) is a common disorder affecting the gastrointestinal tract. The distinctive feature is recurrent abdominal pain associated with altered bowel movements, manifesting as constipation, diarrhea, or fluctuating between both. The...
