Abdominal tuberculosis

  1. 1. Dr. Minhajuddin Khurram AL-AMEEN MEDICAL COLLEGE HOSPITAL, bIJAPUR
  2. 2.  A common disease in India and other developing countries  It the 6th most common type of extra-pulmonary tuberculosis  40% of Indians harbour tb bacilli  In 2010, Global Incidence – 9.4million In india – 2.3million Prevalence in India is 3.1 million 3,20,000 deaths… -WHO
  3. 3.  24th March 1882- World Tb day  TB declared as notifiable disease by INDIAN GOVERNMENT on may9th 2012
  4. 4. 1. Intestinal (Koenig’s syndrome) A. Iliocaecal region  Ulcerative -60%  Hyperplastic-10%  Mixed-30% B. Ileal region  Stricture type 2. Peritoneal tuberculosis A. Acute B. Chronic  Ascitic  Encysted  Plastic  Purulent
  5. 5. 3. Tuberculous mesenteric lymphadenitis A. Calcified lesion B. Acute Meseneteric lymphadenitis C. Pseudo-mesenteric cyst D. Tabes mesenterica E. Chronic Lymphadenitis 4. Ano-recto-sigmoidal 5. Involvement of solid organs as a part of milary tuberculosis 6. Involvement of omentum 7. Rare types A. Oesophageal (0.2% of abdominal) B. Gastroduodenal
  6. 6. 1. By ingestion ◦ Ingestion of food contaminated with tubercle bacilli causing Primary Intestinal Tuberculosis ◦ Ingestion of sputum containing tuberculous bacteria from primary pulmonary focus - Secondary Intestinal Tuberculosis 2. Hematogenous spread from lungs 3. Through lymphatics (neck) 4. Fallopian tubes (retrograde spread)
  7. 7.  Most common site of abdominal tuberculosis due to: ◦ Stasis ◦ Abundant payer’s patches ◦ Alkaline media ◦ Bacterial contact time is more ◦ Minimal digestive activity ◦ Maximum absorption in the area
  8. 8. A. Ulcerative type (60%): ◦ Secondary to pulmonary tuberculosis ◦ Virulent organism ◦ Poor body resistance ◦ Multiple circumferential transverse ulcers (Girdle ulcers) with skip leisons ◦ Commonly in ileum ◦ Rarely in caecum
  9. 9. ◦ Napkin ring strictures in longstanding ulcers (common in ileum) ◦ Intestinal nodes involvement with caseation and abscess ◦ May present with blood in stools, diarrhoea, loss of appetite and reduced weight ◦ Complications:  Acute: Ulcer perforation  Chronic: Stricture  Subacute obstruction
  10. 10. B. Hyperplastic Type -10% ◦ Primary GIT tuberculosis ◦ Less virulent organism ◦ Good body resistance ◦ Chronic granulomatous lesions in ileoceacal region ◦ Fibroblastic activity in submucosa and subserosa causes thickening of bowel wall with lymph node enlargement  Presenting as Mass in Right Iliac Fossa (Nodular fixed and firm mass) ◦ Caseation is very rare
  11. 11. B. Hyperplastic Type -10% ◦ No primary leision in the chest ◦ Complication: May cause sub-acute intestinal obstruction due to mass
  12. 12.  Others ◦ Abdominal pain (90%)  Colicky type in intestinal tuberculosis  Dull aching in mesenteric lymphadenitis ◦ Mass in right iliac fossa (35%)  Hard, nodular, fixed, nontender mass mimicing ca caecum ◦ Subacute intestinal obstruction (20%) ◦ Can be associated with adenocarcinoma of caecum
  13. 13. 1. Ca Caecum 2. Ameboma 3. Appendicular mass 4. Lymph node mass 5. Psoas abscess 6. Crohn’s disease
  14. 14.  Chest Xray – for primary focus  Blood investgations: Mantoux, ELISA, serum IgG  ESR- raised  Plain Xray abdomen ◦ Intestinal obstruction ◦ Calcified lymph nodes ◦ Hollow viscus perforation ◦ Calcified Granuloma in liver
  15. 15.  USG abdomen ◦ Thickened bowel wall ◦ Loculated ascitis ◦ Interloop ascitis ◦ Mesenteric thickening ◦ Lymph node enlargement ◦ Pulled up caecum (Pseudokidney sign)
  16. 16.  Barium study Xray (barium enema or barium follow through) ◦ Pulled up caecum ◦ Obtuse ileocaecal angle; straightening (Goose neck) ◦ Steirlin sign: Hurrying of barium due to rapid flow and lack of barium in inflamed site ◦ Fleischner sign (Inverted umbrella sign): Narrow ileum with thickened ileocaecal valve ◦ Napkin leisons ◦ Chicken intestine: Hypersegmentation ◦ Mega Ileum: Dilatation of proximal ileum
  17. 17.  Barium Study showing Mega Ileum
  18. 18.  Colonoscopy ◦ To rule out ca ◦ Shows mucosal nodules, ulcers, strictures, deformed ileocaecal valve, mucosal oedema and diffuse colitis ◦ Biopsy can be taken to eslablish the diagnosis
  19. 19.  CT Abdomen ◦ CT scan shows thickening of the cecum with pericecal inflammatory changes. Mesenteric lymph nodes are also evident (arrows).
  20. 20.  Diagnostic laproscopy ◦ Direct visualization ◦ Collect acsitic fluid ◦ Take biopsy from mass, omentum or peritoneum
  21. 21.  PCR of tissue  Acsitic tap fluid analysis ◦ Exudate fluid (protein >2.5gm%) ◦ Lymphocyte predominant cells >250 cu mm (upto 4000 cu mm) ◦ Glucose <30mg% ◦ Specefic gravity >1.016 ◦ ADA (Adenosine deaminase activity) 95% specificity and 98% sensitivity ◦ LDH > 90 units/litre
  22. 22. 1. Obstruction 20% 2. Malabsoprption, blind loop syndrome 3. Dissemination of tuberculosis 4. Cold abscess formation 5. Hemorrhage 6. Perforation 7. Fecal fistula
  23. 23.  Mediacal management: ◦ First line drugs:  INH  Rifampicin  Pyrazinamide  Ethambutol ◦ Second line drugs:  Amikacin, kanamycin, PAS, Ciprofloxacin,  Clarithrymycin, Azythromycin, Rifabutin  Drug: RNTCP 2H3R3Z3 E3 + 4H3R3 ◦ Treatment to be continued for 6-9 months ◦ Supportive nutrition
  24. 24.  Surgical Management: ◦ Indications:  Intestinal obstruction  Severe hemorrhage  Acute abdomen (perforation)  Intra-abdominal abscesses/ fistula formation  Uncertain diagnosis
  25. 25.  Surgical Management: 1. Ileocaecal resection with 5 cm margin 2. Stricturoplasty- single stricture 3. Single strictutre with friable bowel : Resection 4. Multiple Strictures: Resection and anastomosis 5. Multiple strictures with long segment gaps: Multiple stricturiplasty
  26. 26.  Surgical Management: 6. Early perforation: resection and anastomosis (due to friable bowels) 7. Perforation with severe contamination: resection with colostomy 8. Adhesiolysis by laproscopy (Very difficult procedure) 9. Drainage of abscesses and treatment for fistula in ano
  27. 27.  It is usually stricture type  May be multiple  Presents with intestinal obstruction  Bowel adhesions, localization, fibrosis, secondary infection are common  Perforation (5%)  Plain Xray – Multiple air fluid levels  Resection and anastomosis with Anti- tubercular drugs
  28. 28.  It is post primary  Becoming more common  Activation of long standing latent foci  Blood spread  Can develop from diseased mesenteric lymph nodes, intestines or fallpian tubes
  29. 29.  Basic pathology ◦ Enormous thickening of the parietal peritoneum ◦ Multiple tiny yellowish tubercles ◦ Dense adhesions in peritoneum and omentum with small intestines ◦ May precipitate obstruction ◦ Thickening of bowel wall
  30. 30.  Abdominal Cocoon Syndrome ◦ Dense adhesions in peritoneum and omentum with contents inside as small bowel causing intestinal obstruction
  31. 31. A.
