A 70-year-old man presents with severe crampy abdominal pain which is worse after eating. Patient also complained of frequent nausea, bloating, watery diarrhoea and weight loss. His other medical problems include coronary aery disease, hypeension and hypercholesterolemia. He has a 30-pack-year smoking history. Barium enema is as shown: Which of the following statement is true?
**Core Concept**
The patient's symptoms and barium enema findings are suggestive of a gastrointestinal condition characterized by chronic inflammation, fibrosis, and narrowing of the intestinal lumen. This is a classic manifestation of **chronic mesenteric ischemia**, a condition that typically affects older adults with significant atherosclerotic risk factors.
**Why the Correct Answer is Right**
The patient's symptoms are consistent with chronic mesenteric ischemia, which is characterized by severe abdominal pain, nausea, bloating, watery diarrhea, and weight loss. The barium enema findings likely demonstrate **intestinal narrowing and irregularities**, which are hallmarks of chronic mesenteric ischemia. This condition is often caused by **atherosclerotic occlusion of the mesenteric arteries**, which reduces blood flow to the intestines and exacerbates symptoms after eating.
**Why Each Wrong Option is Incorrect**
**Option A:** This option is incorrect because it does not accurately describe the patient's symptoms or the barium enema findings. Chronic mesenteric ischemia is characterized by severe abdominal pain, not just mild discomfort.
**Option B:** This option is incorrect because it does not address the patient's significant atherosclerotic risk factors, which are a key contributor to chronic mesenteric ischemia. The patient's smoking history, hypertension, and hypercholesterolemia all increase his risk for atherosclerotic disease.
**Option C:** This option is incorrect because it does not accurately describe the patient's symptoms or the barium enema findings. While the patient does experience abdominal pain, his symptoms are more consistent with chronic mesenteric ischemia than with irritable bowel syndrome.
**Option D:** This option is incorrect because it does not accurately describe the patient's symptoms or the barium enema findings. While the patient does experience weight loss, his symptoms are more consistent with chronic mesenteric ischemia than with malignancy.
**Clinical Pearl / High-Yield Fact**
A key clinical pearl for diagnosing chronic mesenteric ischemia is to look for **severe abdominal pain that worsens after eating**, which is a classic symptom of this condition. This symptom is due to the increased demand for blood flow to the intestines after eating, which is compromised in patients with chronic mesenteric ischemia.
**Correct Answer:** C.
