Multiple strictures in intenstine are found in –
**Core Concept**
Multiple strictures in the intestine refer to the presence of multiple constrictions or narrowings in the intestinal lumen, which can be caused by various factors such as inflammation, scarring, or neoplastic processes. This condition can lead to obstructive symptoms, including abdominal pain, vomiting, and constipation.
**Why the Correct Answer is Right**
The presence of multiple strictures in the intestine is often associated with Crohn's disease, a type of inflammatory bowel disease (IBD) characterized by chronic inflammation of the gastrointestinal tract. Crohn's disease can cause transmural inflammation, leading to fibrosis and stricture formation. The exact mechanism involves the activation of immune cells, release of cytokines, and subsequent tissue damage. The intestinal wall becomes thickened, and the lumen narrows, resulting in multiple strictures.
**Why Each Wrong Option is Incorrect**
* **Option A:** This option is incorrect because while Crohn's disease is a common cause of multiple intestinal strictures, other conditions like scleroderma or radiation enteritis can also cause similar symptoms, but they are less likely to result in multiple strictures.
* **Option B:** This option is incorrect because while certain infections like typhoid fever can cause intestinal strictures, they are typically single or few in number and not multiple.
* **Option C:** This option is incorrect because while intestinal tumors can cause strictures, they are usually single and not multiple.
**Clinical Pearl / High-Yield Fact**
Crohn's disease is a classic cause of multiple intestinal strictures, and its diagnosis often requires a combination of clinical evaluation, endoscopic examination, and imaging studies like CT or MRI enterography.
**Correct Answer:** D. Crohn's disease.
