Abdominal Tuberculosis

Q: Does abdominal TB always need surgery?

No. The majority of patients with abdominal tuberculosis are successfully managed with anti-tuberculous therapy alone. Surgery is reserved for complications that do not respond to medical treatment — intestinal obstruction, perforation, abscess formation, or fistula. Early diagnosis and prompt initiation of ATT significantly reduce the need for surgical intervention.

Q: How long is anti-tuberculous treatment required after bowel surgery?

ATT is typically continued for 6‒9 months total, depending on drug sensitivity and extent of disease. Surgery does not replace ATT — the full course must be completed to eliminate residual mycobacterial infection and prevent relapse.

Q: Can abdominal TB cause permanent bowel damage?

Abdominal TB can cause long-term complications including intestinal strictures, adhesions, short bowel syndrome from extensive resection, and malabsorption. Prompt diagnosis and early treatment with ATT minimise these risks. Nutritional support and regular follow-up are important components of long-term management.

Tuberculous infection affecting the intestines, peritoneum, and lymph nodes — requiring anti-tuberculous therapy as primary treatment, with surgery for complications such as obstruction, perforation, or abscess.

ABOUT THIS CONDITION

What is Abdominal Tuberculosis?

Abdominal tuberculosis (TB) is caused by Mycobacterium tuberculosis involving the gastrointestinal tract, peritoneum, mesentery, and lymph nodes. It is particularly prevalent in South Asia. It may present as intestinal obstruction from strictures, acute abdomen from perforation, ascites from peritoneal involvement, or as a chronic wasting illness with abdominal pain and altered bowel habit. Diagnosis is confirmed by tissue biopsy, AFB culture, or GeneXpert PCR. Dr. Tagore Mohan Grandhi manages surgical complications of abdominal tuberculosis at Lux Hospitals, Hyderabad. Anti-tuberculous therapy (ATT) is the cornerstone of treatment. Surgery is reserved for complications not amenable to medical therapy — bowel obstruction, perforation, abscess, or fistula. Short bowel-conserving resections with temporary stoma formation are performed to manage complications safely.

SIGNS TO WATCH

Common Symptoms

⚠️

Symptoms that need attention

Chronic abdominal pain, distension, and altered bowel habit Constitutional symptoms — fever, night sweats, and weight loss Ascites causing progressive abdominal distension Acute bowel obstruction from ileocaecal stricture Acute peritonitis from intestinal perforation Palpable abdominal mass from mesenteric lymphadenopathy

WHY IT HAPPENS

Causes & Risk Factors

Mycobacterium tuberculosis infection via ingested organisms or haematogenous spread from pulmonary TB
Ileocaecal region most commonly affected due to high lymphoid tissue density
Immunosuppression from HIV, diabetes, malnutrition, or corticosteroid use
Endemic exposure in regions of high TB prevalence
Inadequately treated or drug-resistant pulmonary tuberculosis
Consumption of unpasteurised milk with M. bovis in rural settings

HOW WE TREAT IT

Treatment Approach

✦

Anti-Tuberculous Therapy First

Anti-tuberculous therapy is the definitive treatment for abdominal tuberculosis. Surgery is performed only for complications that do not respond to medical therapy. Dr. Grandhi works closely with infectious disease physicians to ensure appropriate ATT is started promptly, minimising the need for surgical intervention and optimising surgical outcomes when surgery is required.

Available at Lux Hospitals, Hitech City, Hyderabad

1

Diagnosis & Infectious Disease Review

CT abdomen, colonoscopy with biopsy, ascitic fluid analysis, and GeneXpert PCR confirm the diagnosis. HIV testing and sputum culture exclude pulmonary TB. Infectious disease team initiates ATT.
2

Anti-Tuberculous Therapy

Standard first-line ATT (rifampicin, isoniazid, pyrazinamide, ethambutol) is commenced for 2 months, followed by a continuation phase. Most patients improve significantly without surgery.
3

Surgery for Complications

Bowel obstruction from ileocaecal stricture not resolving on ATT requires laparoscopic or open resection. Perforation requires emergency resection and peritoneal washout with temporary stoma formation.
4

Post-operative ATT & Nutritional Support

ATT is continued for the full treatment duration of 6‒9 months post-operatively. Nutritional rehabilitation, iron supplementation, and close follow-up monitor for disease recurrence.

AVAILABLE TREATMENTS

TreatmentOptions

Primary Bowel Resection

Resection of the diseased ileocaecal or intestinal segment with primary anastomosis for obstruction or stricture not responding to medical therapy.

Bowel Resection with Colostomy

Resection with stoma formation for perforated bowel or severely contaminated abdomen where primary anastomosis is unsafe.

Ileostomy

Formation of a defunctioning ileostomy to protect a distal anastomosis or manage complex fistulas in the context of active tuberculosis.
