Diseases of the Liver and Gallbladder01:26

Diseases of the Liver and Gallbladder

882
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...

Bile01:19

Bile

1.4K
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.
Bile is released when dietary fats enter...

Gallbladder01:17

Gallbladder

790
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...

Chronic Bowel Disorders: Introduction01:17

Chronic Bowel Disorders: Introduction

525
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...

Hepatic Drug Excretion: Influencing Factors01:16

Hepatic Drug Excretion: Influencing Factors

189
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...

    Area of Science:

    • Oncology
    • Gastroenterology
    • Surgical Oncology

    Background:

    • Biliary tract malignancies are aggressive gastrointestinal cancers.
    • Late diagnosis often precludes radical surgical treatment.
    • Surgical resection is the only curative option for these tumors.

    Purpose of the Study:

    • To present the experience of our department in the diagnosis and treatment of biliary tract tumors.
    • To evaluate treatment outcomes for biliary tract malignancies.

    Main Methods:

    • Retrospective review of patients diagnosed and treated between 2005 and 2021.
    • Analysis of treatment modalities including radical resection, symptomatic management, biliary stenting, and external-internal drainage.
    • Assessment of adjuvant oncological treatment in operated and non-operated patients.

    Main Results:

    • Radical (R0) resection was performed in 28.4% of patients.
    • Biliary stenting and drainage were definitive procedures in 43.2% of patients.
    • Median overall survival and progression-free survival in operated patients were 19.9 and 15.7 months, respectively, with significantly better overall survival (p<0.05).

    Conclusions:

    • Surgical resection, when feasible, significantly improves survival outcomes for biliary tract cancer patients.
    • Multidisciplinary management including palliative procedures and adjuvant therapy is crucial for non-resectable cases.
    • Further research is needed to optimize treatment strategies for these challenging malignancies.
