Crohn’s disease is associated with following
**Core Concept**
Crohn's disease is a type of inflammatory bowel disease (IBD) characterized by chronic inflammation of the gastrointestinal tract, leading to symptoms such as abdominal pain, diarrhea, weight loss, and fatigue. The exact cause of Crohn's disease is unknown, but it is believed to result from a combination of genetic, environmental, and immune system factors.
**Why the Correct Answer is Right**
Crohn's disease is associated with an increased risk of developing colorectal cancer, particularly in patients with a long-standing history of the disease. This is thought to be due to the chronic inflammation and mucosal damage that occurs in Crohn's disease, which can lead to genetic mutations and dysplasia in the colon. The risk of colorectal cancer in Crohn's disease is estimated to be 2-8% after 10 years of disease, and 18-30% after 30 years.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because while Crohn's disease can cause malabsorption, it is not the primary association.
**Option B:** This option is incorrect because while Crohn's disease can cause fistulas, it is not the most significant association.
**Option C:** This option is incorrect because while Crohn's disease can cause arthritis, it is not the primary association.
**Clinical Pearl / High-Yield Fact**
It's essential to remember that patients with Crohn's disease are at an increased risk of developing colorectal cancer, and regular surveillance colonoscopies are recommended to detect dysplasia and cancer early.
**Correct Answer: D. Colorectal cancer.
