**Core Concept:** Tuberculosis is a bacterial infection caused by Mycobacterium tuberculosis, primarily affecting the lungs (pulmonary tuberculosis), but can also involve other organs like the intestines (extrapulmonary tuberculosis). Extrapulmonary tuberculosis often presents with vague symptoms, making diagnosis and treatment challenging. Intestinal tuberculosis is an uncommon presentation, but when present, it can cause significant morbidity and mortality.

**Why the Correct Answer is Right:** The correct answer is "C. Obstructive symptoms" because intestinal tuberculosis most commonly presents with obstructive symptoms due to the formation of strictures, abscesses, or fistulae. These symptoms can include abdominal pain, distension, and constipation, often leading to intestinal obstruction.

**Why Each Wrong Option is Incorrect:**

A. "Anemia" (Option A): While anemia is a known complication of intestinal tuberculosis, it is not the most common indication for surgery. Obstructive symptoms are the primary reason for surgery in this situation.

B. "Diarrhea" (Option B): Diarrhea can be present in intestinal tuberculosis, but it is not the primary indication for surgery. Obstructive symptoms are the key factor driving surgical intervention.

D. "Persistent fever" (Option D): Persistent fever can be present in intestinal tuberculosis, but it is not the primary indication for surgery. Obstructive symptoms are the key factor driving surgical intervention.

**Clinical Pearl:** Tuberculosis is a global health concern, particularly in developing countries. Intestinal tuberculosis should be considered in the differential diagnosis for patients presenting with obstructive symptoms, even in the absence of typical radiological findings. Prompt diagnosis and treatment are essential to prevent complications like obstruction, perforation, and malabsorption.

**Core Concept:** Surgical intervention for intestinal tuberculosis is usually indicated when obstructive symptoms, such as abdominal pain, distension, and constipation, persist despite medical treatment.

**Why the Correct Answer is Right:** Intestinal tuberculosis can often be misdiagnosed due to its non-specific symptoms and radiological findings. Unlike pulmonary tuberculosis, intestinal tuberculosis often presents with non-specific symptoms and may mimic other diagnoses like malignancy or inflammatory bowel disease. In these cases, surgery is warranted to relieve life-threatening complications like obstruction, perforation, and malabsorption.

**Why Each Wrong Option is Incorrect:**

A. "Ulcerative colitis" (Option A): Ulcerative colitis is a type of inflammatory bowel disease (IBD) characterized by chronic inflammation of the large intestine. While surgery may be considered in severe cases, it is not the primary indication for surgery in intestinal tuberculosis.

B. "Gastrointestinal bleeding" (Option B): Gastrointestinal bleeding can occur in intestinal tuberculosis, but it is not the primary indication for surgery. Complications like obstruction and malabsorption are more likely to lead to surgical intervention.

C. "Obstructive jaundice" (Option C): Obstructive jaundice is a potential complication of intestinal tuberculosis, but it is not the primary indication for surgery. Life-threatening complications like obstruction, perforation, and malabsorption are
