In intestinal obstruction, investigations needed are ?
**Core Concept**
Intestinal obstruction is a condition where there is a blockage in the intestine that prevents normal flow of intestinal contents. The diagnosis of intestinal obstruction involves a combination of clinical evaluation and diagnostic tests. **Imaging studies** and **laboratory tests** play a crucial role in confirming the diagnosis.
**Why the Correct Answer is Right**
The correct answer involves a range of investigations including abdominal X-rays, CT scans, and blood tests to assess for signs of obstruction, ischemia, or infection. These tests help identify the location and cause of the obstruction, guiding further management. **Abdominal X-rays** can show dilated bowel loops and air-fluid levels, while **CT scans** provide more detailed information about the obstruction site and potential causes.
**Why Each Wrong Option is Incorrect**
**Option A:** Incomplete options do not provide sufficient information for diagnosis.
**Option B:** Insufficient investigations may lead to delayed diagnosis.
**Option D:** Incorrect investigations may mislead the diagnosis.
**Clinical Pearl / High-Yield Fact**
A key point to remember is that in cases of suspected intestinal obstruction, **abdominal X-rays** are often the first-line imaging study due to their availability and ability to quickly identify signs of obstruction.
**Correct Answer:** D. Abdominal X-ray, CT scan, blood tests for diagnosis of intestinal obstruction.
