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 the common...
Giardiasis01:12

Giardiasis

Giardiasis is a globally prevalent intestinal infection caused by the protozoan parasite Giardia duodenalis (also known as G. lamblia or G. intestinalis). This flagellated protozoan is the most frequently identified intestinal parasite in the United States and worldwide. Transmission primarily occurs via the fecal-oral route, with infection arising from ingestion of water or food contaminated with cysts. Individuals in low-resource settings, international travelers, outdoor enthusiasts, daycare...
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...
Amebiasis01:28

Amebiasis

Entamoeba histolytica, a protozoan parasite, is responsible for intestinal and extraintestinal amebiasis. Though a significant proportion of infections remain asymptomatic, approximately 50 million individuals annually are estimated to present with clinical disease, resulting in up to 100,000 deaths globally. The disease burden is disproportionately high in regions with lower socioeconomic status, such as parts of India, Africa, Mexico, and Latin America.Etiology and TransmissionThe infective...
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 related to...
Ascites01:19

Ascites

DefinitionAscites is the buildup of fluid inside the peritoneal cavity. It occurs when fluid moves out of the vascular system faster than the peritoneal lymphatics can remove it. This fluid shift is most commonly seen in liver cirrhosis but can also appear in several other systemic disorders.EtiologyCirrhosis remains the leading cause of ascites. Other conditions that can contribute include:Heart failureConstrictive pericarditisAbdominal cancersNephrotic syndromeSevere protein–calorie...

Summary
This summary is machine-generated.

Gallbladder ascariasis, caused by Ascaris lumbricoides, can lead to acalculous cholecystitis. Ultrasound is a sensitive, noninvasive tool for diagnosing this rare condition and monitoring worm movement.

Area of Science:

  • Hepatobiliary surgery
  • Parasitology
  • Diagnostic imaging

Background:

  • Gallbladder ascariasis, caused by Ascaris lumbricoides, is a rare clinical entity.
  • The presence of Ascaris lumbricoides in the gallbladder can precipitate acalculous cholecystitis.

Purpose of the Study:

  • To investigate gallbladder ascariasis.
  • To analyze the clinical presentation, diagnosis, and management of gallbladder ascariasis.

Main Methods:

  • A retrospective case study of 28 patients diagnosed with gallbladder ascariasis between 2005 and 2010.
  • Abdominal sonography was utilized for diagnosis and monitoring.

Main Results:

  • Ultrasound revealed worms as linear echogenic shadows or exhibiting 'belly dance' movements.
  • Twenty-one patients presented with acute acalculous cholecystitis, and seven with biliary colic.
  • Spontaneous worm expulsion occurred in 22 patients; six underwent cholecystectomy, two emergently.

Conclusions:

  • Ultrasound is a highly sensitive and noninvasive diagnostic method for suspected gallbladder ascariasis.
  • Repeated ultrasound examinations are valuable for monitoring worm activity in the gallbladder and common bile ducts.
