ABDOMINAL TUBERCULOSIS
TUBERCULOSIS
 Major health problem
 7-10 million new cases annually
 6% of deaths world wide
 Abdominal tuberculosis is a common extrapulmonary
manifestation of tuberculosis.
 Of non HIV patients 10 – 15 % have extrapulmonary manifestations of
tuberculosis .
 HIV infected patients > 50% have extra pulmonary manifestations of
tuberculosis
There is a resurgence of abdominal tuberculosis due to multidrug resistance and co
existence of HIV – AIDS.
 In India, around 3 – 20 % of all cases of bowel obstruction are due
to tuberculosis.
 Tuberculosis accounts for 5 – 9 % of all small intestinal perforations
in India, second commonest cause after typhoid fever.
 Abdominal tuberculosis is an important cause of Malabsorption
syndrome in India.

• Epidemiology:
– Both gender: equally affected
– Most common age: 35-45 years
• Riskfactors:
– Alcoholic liver disease
– HIV infection
• 9% of all new TB cases are related to HIV
– Advanced age
– Low socioeconomic status
Etiology
Mycobacterium tuberculosis
Pathogen for most cases of abdominal tuberculosis
Mycobacterium bovis
Cause in small percentage of cases, in developing countries.
Transmitted by unpasteurized diary products.
 Mycobacterium Avium complex
more likely in HIV infected patients
Agent
Mode of infection
Swallowing of
infected sputum
Hematogenous spread
from pulmonary focus
Ingestion of contaminated
milk products
Direct spread from
adjacent organs
Pathogenesis of abdominal TB
Potential fates..
The bacilli have 4 potential fates:
1. They may be killed by the immune system,
2. They may multiply and cause primary TB,
3. They may become dormant and remain
asymptomatic, or
4. They may proliferate after a latency period
(reactivation disease).

Differential Diagnosis
Diagnosis: intestinal TB or CD
• They can present exactly with same clinical
pictures (same age group, symptoms and
signs)
• Same radiological findings and same
endoscopic findings
• Mostly with same pathological findings
• So how can we make the diagnosis?
Blood tests
• No specific diagnostic blood tests available
• Common blood parameters:
– Elevated ESR
• Almost always raised but not exceed 60 mm/hr
– Mild anemia
• normochromic/ normocytic
– Mild leukocytosis
– Raised CRP
– Hypoproteinemia
– Hypoalbuminemia
Tuberculinskin test
A +ve tuberculin skin test has been reported in 55 to
100 % pts. with abdominal tuberculosis. However in
areas where TB is highly endemic , +ve tst neither
confirms the diagnosis of abdominal TB nor excludes
it
30
QUANTI-FERON TB TEST
 Whole blood cytokine assay
 Approved by U.S. food and drug administration as an aid
in the diagnosis of latent TB infection
 Recommended for screening for latent TB infection in
population at low risk of TB.
 The test‘s performance will probably be enhanced by
use of antigen such as ESAT-6 and CPF-10 that are
present in M. tuberculosis but absent in others.
31
Concomitant PTB
• Concomitant PTB
– Present in 15-25% only

COMPUTED TOMOGRAPHY
• Abdominal lymphadenopathy -commonest
manifestation
• Enlarged lymph nodes
– mesenteric,
– peri-portal,
– peri-pancreatic, and
– upper para-aortic groups of nodes.
CECT
• The CECT have been described as –
peripheral rim enhancement,
non-homogenous enhancement,
homogenous enhancement and
homogenous non-enhancement, in that order of
frequency.
• Different patterns are seen same nodal group,
possibly related to the different stages of the
pathological process.
CECT
• Conglomerate mass of
6cm.
• Enlarged nodes with
hypo enhancing areas
are seen.
CECT
• presence of nodal calcification in the absence
of a known primary tumour in patients from
endemic areas suggests a tubercular aetiology
.
• CECT imaging criteria differentiating
abdominal lymph node enlargement due to
tuberculosis or lymphoma suggested some
differences in the anatomic distribution and
the CT enhancement patterns
CECT
CECT FINDINGS Tuberculosis lymphoma
Lymph nodes lesser omental,
mesenteric, and upper
para-aortic
lower para-aortic lymph
nodes
Lymphadenopathy features peripheral rim
enhancement, frequently
with a multilocular
appearance
homogenous
attenuation.
CECT
• Ascites can be free or loculated.
• Characteristically, it is a high density ascites which
could be because of high protein and cellular contents
of the fluid.
• Mesenteric involvement and presence of
macronodules (> 5mm in diameter),
a thin omental line (fibrous wall covering the infiltrated
omentum),
peritoneal or extraperitoneal masses with low density
centres and calcification,
and splenomegaly or splenic calcification have been more
commonly seen with tuberculous peritonitis.
CECT
• High density ascitic fluid
• Peritonial and
mesenteric thickening
and enhancement are
seen.
CECT
• The diagnosis of tuberculosis is suggestive
when
loculated fluid collections are detected in the
presence of omental infiltration,
peritoneal enhancement,
transperitoneal reaction, and
mesenteric or bowel involvement.
mural thickening affecting the ileocaecal region.

Endoscopy
 Colonoscopy is of value to rule out malignancy.
 It is easiest and most direct method in establishing
the diagnosis.
 Shows mucosal nodules or ulcers , deformed ileo
caecal valve, mucosal oedema and pseudopolyps
and occasionally diffuse colitis. Biopsy can be taken
to confirm diagnosis.
 Capsule endoscopy is also useful to see small
intestine pathology in difficult cases .
56
Nodules
Variable sizes (2 to 6mm)
Non friable
Most common in caecum especially near IC valve.
Tubercular ulcers
Large (10 to 20mm) or small (3 to 5mm)
Located between the nodules
Single or multiple
Transversely oriented / circumferential contrast to Crohns
Healing of these ‘girdle ulcers’ strictures
Deformed and edematous ileocaecal valve

Microbiology and histology exam
Definitive diagnosis:
• Ziehl-Neelsen stain for
AFB
• Tissue culture for
mycobacteria
• Caseating granulomas on
histology
Tissue Biopsy
• Peritoneal tapping
• Endoscopic biopsy
• Laparoscopy
• Laparotomy
Histological
exam
Microbiological
Smear & culture
Molecular Methods
• Polymerase chain reaction (PCR)
– PCR analysis for Mycobacterium tuberculosis
complex in tissues
– Reported as 100% sensitivity in some series
Peritoneal tapping
• Ziehl-Neelsen stain: 3% positive
– At least 5000 bacteria/ ml is required
• Culture for AFB: 35% positive
– At least 10 bacteria is required
– 66-83% positive if 1L of ascitic fluid is cultured after centrifugation
Diagnostic laproscopy
Direct visualization
Collect acsitic fluid
Take biopsy from mass, omentum or peritoneum
is very useful method of investigation .
 Transabdominal peritoneoscopy is visualization of
the peritoneal cavity using endoscope through
small incision in the abdomen.
 It aids in visualization ,to collect ascitic fluid for
analysis and to biopsy.
