Summary
Biliary Ascariasis, caused by Ascaris lumbricoides worms in the bile ducts, can lead to serious complications. This case highlights diagnosis via imaging and ERCP in a patient with abdominal pain.
Area of Science:
- Hepatology and Gastroenterology
- Infectious Diseases
- Parasitology
Background:
- Biliary Ascariasis is a parasitic infection where Ascaris lumbricoides infest the biliary tract.
- This condition can precipitate severe biliary complications, including obstruction, cholangitis, cholecystitis, and acute pancreatitis.
Observation:
- A 37-year-old female presented with persistent upper abdominal pain, nausea, vomiting, and unintentional weight loss.
- Initial ultrasound revealed a dilated common bile duct containing a linear, echogenic structure, suggestive of a parasitic presence.
Findings:
- Endoscopic Retrograde Cholangiopancreatography (ERCP) definitively diagnosed Biliary Ascariasis by visualizing large adult Ascaris lumbricoides within the biliary system.
- The diagnostic imaging successfully identified the parasitic etiology of the patient's gastrointestinal and biliary symptoms.
Implications:
- This case underscores the importance of considering parasitic infections in the differential diagnosis of biliary diseases, particularly in endemic areas.
- Accurate and timely diagnosis through imaging modalities like ultrasound and ERCP is crucial for effective management and prevention of complications associated with Biliary Ascariasis.

721
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...

01:26Diseases of the Liver and Gallbladder
867
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...

01:30Acute Pancreatitis II: Clinical Manifestations and Management
165
Acute pancreatitis presents a complex medical emergency characterized by rapid onset inflammation of the pancreas, demanding timely diagnosis and management to prevent complications. The condition primarily manifests through severe upper abdominal pain that often radiates to the back. This pain intensifies following the consumption of fatty foods. Accompanying symptoms such as nausea, vomiting, abdominal distention, fever, dyspnea, cyanosis, and jaundice can vary in intensity but significantly...

01:26Endoscopic Procedures V: ERCP
671
Endoscopic Retrograde Cholangiopancreatography (ERCP) is a diagnostic procedure that combines endoscopy and fluoroscopy to diagnose and treat conditions related to the bile ducts, pancreatic ducts, and gallbladder. This procedure is beneficial for identifying and addressing blockages, gallstones, strictures, and tumors within the biliary or pancreatic systems. ERCP is both diagnostic and therapeutic, offering the ability to visualize and treat identified problems in one session.

01:17Chronic Bowel Disorders: Introduction
516
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...
