The large and small intestines are to be examined in connection with regard both to their general condition, and especially to that of the serous coat. The size of the intestinal canal depends upon two conditions: the quantity of contents and degree of contraction of the muscular coat. Distention can occur due to fecal matter or gas (meteorism). The color of the exterior reflects distention, contents, and amount of blood present; pale grayish-white indicates high distention, while yellow or brown suggests bile presence. Hyperemia is distinguished by its diffuse, pale character compared to injected vessels seen in severe inflammation.
<Callout type="important" title="Critical Observation">The hypersemic vessels do not always lie near the surface only but are faintly seen in deeper portions (mucous and submucous coats), indicating local causes within the abdominal cavity.</Callout>
Changes in the peritoneal coat include dark coloration indicative of severe chronic inflammation, such as dysentery. Extensive adhesive inflammation can bind all coils of intestine into one large mass, necessitating incisions to trace separate ones.

The chapter also discusses changes due to strangulation, encapsulated peritonitic abscesses, tumors, and methods for opening intestines during examination. The contents of the intestine are examined for quantity, color, consistency, odor, and any abnormal admixture.
Key Takeaways
- Intestinal examination involves assessing size, distention, and serous coat condition.
- Hyperemia in the intestinal wall can indicate severe inflammation or stasis.
- Dark coloration of the outer wall suggests chronic conditions like dysentery.
Practical Tips
- Use a strong stream of water to ever turn intestines inside out for thorough examination.
- When examining contents, note quantity, color, consistency, and odor for diagnostic clues.
Warnings & Risks
- Hyperemic vessels may be faintly seen in deeper portions indicating local causes within the abdominal cavity.
- Necrosis of the serous coat can lead to perforation of the intestine.
Modern Application
While this chapter focuses on detailed pathological examination techniques from the late 19th century, its principles remain relevant today. Understanding color changes and structural alterations in intestines aids modern medical practitioners in diagnosing conditions like inflammatory bowel disease or infections. However, modern imaging technologies have largely replaced manual inspection for initial diagnosis.
Frequently Asked Questions
Q: What does a dark coloration of the intestinal wall indicate?
A dark coloration of the intestinal wall typically indicates severe chronic inflammation, such as dysentery.
Q: How can one distinguish hyperemia from injected vessels in the intestine?
Hyperemic vessels are distinguished by their diffuse and pale character compared to injected vessels which are more localized and easily recognized.
Q: What is a risk associated with deep intestinal ulcers?
Deep intestinal ulcers can lead to necrosis of the serous coat, potentially causing complete destruction and perforation of the intestine.
