Grey-scale ultrasonography in cholestatic jaundice
Gut
|January 1, 1979
Summary
Grey-scale ultrasonography accurately identified medical jaundice causes in 14 patients and distinguished obstructive causes in 41. This safe, cost-effective imaging is recommended as the initial diagnostic step for jaundiced patients.
Area of Science:
- Medical Imaging
- Gastroenterology
- Diagnostic Radiology
Background:
- Jaundice necessitates accurate etiological diagnosis for effective patient management.
- Distinguishing between medical (intrahepatic) and obstructive (extrahepatic) causes of jaundice is critical.
Purpose of the Study:
- To evaluate the diagnostic accuracy of grey-scale ultrasonography in differentiating medical and obstructive causes of jaundice.
- To assess the utility of ultrasonography as a primary imaging modality for jaundiced patients.
Main Methods:
- Prospective study involving 55 jaundiced patients.
- Grey-scale ultrasonography performed without detailed clinical information.
- Analysis of ultrasound findings against confirmed diagnoses.
Main Results:
- Satisfactory ultrasound images obtained in 54 patients; bile duct calibre correctly reported in 96%.
- All 14 medical jaundice cases correctly identified; 23 of 41 obstructive cases correctly diagnosed.
- Specific diagnoses included pancreatic cancer (12/14), gallstones (5/15), bile duct compression (5/5), and metastases (1/1).
Conclusions:
- Grey-scale ultrasonography demonstrates high accuracy in identifying medical jaundice and differentiating obstructive causes.
- Ultrasonography is a safe, inexpensive, and well-tolerated initial investigation for jaundiced patients.
- The modality provides crucial diagnostic information guiding subsequent patient management.

01:17Ultrasonography
Ultrasonography is an imaging technique that uses high-frequency sound waves to visualize the body's internal structures. It is a non-invasive and safe procedure that does not involve the use of ionizing radiation, making it widely used in various medical fields. Ultrasonography is used to study heart function, blood flow in the neck or extremities, certain conditions such as gallbladder disease, and fetal growth and development.

01:27Liver Histology
The microscopic anatomy of the liver is a complex and intricate system that comprises numerous structural units known as liver lobules, each of which is comparable in size to a sesame seed. These hexagonal structures consist of plates of liver cells or hepatocytes, which are characterized by their versatility and abundance of cellular apparatus like rough and smooth ER, Golgi apparatus, peroxisomes, and mitochondria.

Introduction:
Abdominal ultrasonography, commonly known as abdominal ultrasound, is a vital, non-invasive medical imaging technique widely used in healthcare.
Procedure:
This diagnostic tool allows the clinician to visually inspect internal structures within the abdomen, including vital organs such as the liver, gallbladder, pancreas, kidneys, and spleen.
The abdominal ultrasound process begins with applying a special gel to the patient's skin over the abdomen. This gel enhances the...

01:25Jaundice
Jaundice, or icterus, is the yellow discoloration of the skin, sclerae, and mucous membranes. It happens when plasma bilirubin levels rise above 2.5-3 mg/dL, leading to bilirubin deposition in tissue.Bilirubin is a byproduct of hemoglobin degradation. In macrophages, hemoglobin breaks down into globin and heme. Globin is converted into amino acids, while heme is turned into biliverdin by heme oxygenase, which is then reduced to unconjugated bilirubin by biliverdin reductase.Unconjugated...
