The bile is discharged directly into the intestine or externally through a fistula in the abdominal walls, as the skin usually becomes perforated in these cases. In order to be able to determine accurately the above con- ditions, the liver is, of course, not to be previously removed ; if it is taken out the affected parts must also be removed in connection with it.
- Internal Examination. (a.) The Contents. After the examination of the exterior is completed, the gall-bladder is to be opened by a longitudinal incision, in order to examine the contents., which normally vary consider- ably in quantity, color, and composition. The color is either light or dark yellow, reddish-yellow, greenish-yellow, or sometimes almost black. The bile is sometimes thick, again quite fluid, and always stringy. A large quantity of fluid, which is but slightly, or not at all tinged with bile, consti- tutes the so-called dropsy of the gall-bladder (from closure of the outlet). The most common pathological conditions met with are concretions (cholelithiasis), which appear either in the form of small particles, rendering the contents gruel-like, or as large compact calculi, which may even attain the size of the gall-bladder in extreme cases, so that one stone completely fills the cavity. The number of stones is often very large. When such is the case their size is generally correspondingly small. When several are present they are angular, pos- sess sharp edges and smooth facets, in consequence of which they are enabled to lie in close contact with each other. These surfaces are not the result of attrition, as the angu- lar shape is due to the fact that the addition of new concre- tion can only take place at those points where contiguous stones do not lie in contact with each other.

Most calculi are composed of two constituents, pig- ment-lime and Cholesterine, which occur either alone or vari- ously combined.
The gall-stones do not always lie free in the cavity of the bladder, but sometimes in small pockets (diverticula) con- nected with the wall ; the communication between the diver- ticulum and bladder may become closed by inflammation, so that the stone appears to lie entirely outside of the blad- der. Closure of the cystic duct (which must always be slit open when not perfectly free) is usually due to gall-stones which 20 306 DIAGNOSIS IN PATHOLOGICAL ANATOMY.
The Walls. The examination begins with the surface, which is remark- able for its peculiar folds., presenting a honey-combed ap- pearance, which disappears when the bladder is distended in hydrops. These folds disappear also in chronic fibrous in- flammation, such as often appears in cases of cholelithiasis of long standing, in carcinoma, etc.
The liver examination follows with attention to its dimensions and color changes indicative of various diseases. <Callout type="warning" title="Dangerous Condition">Intense icterus can be produced by the mere pressure of the portal glands upon the bile-ducts.</Callout> The liver's size, shape, and consistency are critical indicators of health conditions such as fatty infiltration, amyloid degeneration, cancerous affections, and cirrhosis.

Key Takeaways
- Accurate diagnosis of gallbladder conditions requires careful examination of bile contents, including color and composition.
- Liver size, shape, and consistency are crucial indicators for diagnosing various liver diseases.
- Internal examinations must include the assessment of blood vessel condition within the liver.
Practical Tips
- Always ensure the gall-bladder is thoroughly examined for signs of cholelithiasis to prevent complications.
- Recognize color changes in the liver surface as they indicate specific health conditions such as fatty infiltration or cirrhosis.
- Understand that certain diseases, like chronic fibrous inflammation, can cause significant alterations in the liver's appearance.
Warnings & Risks
- Failure to properly examine and identify gallstones can lead to severe complications including bile duct obstruction.
- Intense icterus may occur due to portal gland pressure on bile-ducts, indicating a serious health issue requiring immediate attention.
Modern Application
While the diagnostic methods described here are outdated by modern medical standards, understanding these historical techniques provides valuable insight into the progression of pathological anatomy. The principles of examining liver and gallbladder conditions remain relevant today, emphasizing the importance of thorough internal examinations to accurately diagnose diseases.
Frequently Asked Questions
Q: What is the significance of bile color in diagnosing gallbladder issues?
The color of bile can indicate various pathological conditions such as cholelithiasis or dropsy of the gall-bladder. Light yellow, dark yellow, reddish-yellow, greenish-yellow, and even black colors are observed depending on the condition.
Q: How does chronic fibrous inflammation affect the liver's appearance?
Chronic fibrous inflammation causes the liver surface to lose its honey-combed appearance due to folds disappearing. The mucous membrane turns white and firm in consistency, indicating significant changes in the organ's structure.
Q: What are some common signs of liver disease based on size and shape?
Liver diseases such as fatty infiltration, amyloid degeneration, cancerous affections, and cirrhosis can cause enlargement or atrophy. The liver may also exhibit irregularities in shape due to conditions like syphilitic affection or spinal curvature.
