Abstract

Insights

Bacterial colonization of gallstones and bile was identified in 16 patients, with enteral bacteria being most common. This highlights the risk of gallstones causing post-cholecystectomy complications.

Area of Science:

  • Gastroenterology
  • Microbiology
  • Surgical Pathology

Background:

  • Lost gallstones in the abdominal cavity can lead to severe complications like abscesses and gastrointestinal perforation.
  • These complications, including gallstones in unusual locations (hernias, respiratory tract), can manifest years after surgery and often require surgical intervention.

Purpose of the Study:

  • To investigate the microbiological profile of gallstones and bile samples post-cholecystectomy.
  • To identify the types of bacteria colonizing gallstones and their potential association with gallbladder inflammation.

Main Methods:

  • Collected 50 gallstones and bile samples from 50 patients undergoing cholecystectomy.
  • Performed microbiological examination on all collected samples.

Main Results:

  • Bacterial colonization was found in 16 cases (32%).
  • Enteral bacteria (e.g., E. coli, E. faecalis) were identified in 13 cases, while non-enteral bacteria were found in 3 cases.
  • Inflammatory signs (acute and chronic) were observed in the gallbladder of several patients with bacterial colonization.

Conclusions:

  • Gallstones harbor diverse bacterial species, increasing the risk of post-operative complications.
  • Microbiological analysis of gallstones is crucial for understanding and managing potential complications.

Cholecystitis01:20

Cholecystitis

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...

Gallbladder01:17

Gallbladder

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...

Microbiota of the Stomach and Small Intestine01:27

Microbiota of the Stomach and Small Intestine

The human gastrointestinal (GI) tract is characterized by distinct physicochemical conditions that shape its microbial communities. Among these, the stomach presents a particularly challenging environment for microbial colonization due to its highly acidic pH, ranging from 1 to 3. This extreme acidity effectively limits microbial density. However, certain acid-tolerant microorganisms are capable of surviving in this niche. Notably, Helicobacter pylori can colonize the gastric mucosa,...

What is Monogastric Digestion?01:50

What is Monogastric Digestion?

The human body contains a monogastric digestive system. In a monogastric digestive system, the stomach only contains one chamber in which it digests food. Several other animal species also have monogastric digestive systems, including pigs, horses, dogs, and birds. This chapter, however, focuses on the human digestive system.

Microbiota of the Urogenital Tract01:28

Microbiota of the Urogenital Tract

The human urogenital system, once thought to be sterile in healthy individuals, is now recognized as a complex microbial habitat. Advancements in molecular sequencing techniques have revealed that even in healthy adults, the kidneys and bladder harbor microbial populations similar to those found in the distal urethra, albeit in much lower abundance. These resident microorganisms, while generally innocuous, can become opportunistic pathogens under conditions that alter the urogenital...

Diseases of the Liver and Gallbladder01:26

Diseases 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...
