Colonoscopy in the diagnosis of intestinal tuberculosis in asymptomatic patients.

BACKGROUND: Colonoscopy with terminal ileoscopy is crucial for the diagnosis of intestinal tuberculosis. This report describes characteristic endoscopic findings in patients with intestinal tuberculosis with few or no clinical symptoms. METHODS: Data for 11 consecutive patients in whom a diagnosis of intestinal tuberculosis was made during the last 15 years in one facility were reviewed. Clinical findings and the frequency of endoscopic findings were evaluated. Mucosal lesions were classified into 4 types: type 1, circumferential ulceration with nodules; type 2, round or irregularly shaped small ulcers, arranged circumferentially, without nodules; type 3, multiple erosions restricted to the large intestine; and type 4, small ulcers or erosions restricted to the ileum. The gross endoscopic appearance of healed lesions included patulous ileocecal valve, pseudodiverticular deformity, and atrophic mucosal areas with aggregated ulcer scars. RESULTS: Only one patient had remarkable clinical symptoms (anorexia and weight loss), whereas, the other 10 had few or no symptoms. The frequency of type 1, 2, 3, and 4 endoscopic findings was, respectively, 36%, 36%, 9%, and 18%. The frequencies for patulous ileocecal valve, pseudodiverticular deformity, and atrophic mucosal area were, respectively, 45%, 45%, and 91%. CONCLUSIONS: When colonoscopy is performed in asymptomatic patients, it is important to be aware of subtle endoscopic findings that are characteristic for intestinal tuberculosis. Recognition of such findings may lead to a correct diagnosis of early stage intestinal tuberculosis.

Diagnosis of ileocecal and colonic tuberculosis by colonoscopy.

The colonoscopic findings in 11 proven cases of ileocecal tuberculosis consisted of deformed ileocecal valve in all 11 and contracted cecal lumen in 10. This was associated with mucosal nodules predominantly around the ileocecal valve, pseudopolypoid folds, and mucosal protuberance. Two patients had an isolated cecal ulcer. In three of the 11 patients the examination enabled a histologic diagnosis to be made on the basis of typical granuloma. In the other four patients Mycobacterium tuberculosis was isolated from the tissue obtained through biopsies.

Endoscopic diagnosis of segmental colonic tuberculosis.

We report colonoscopic findings in 29 proven cases of segmental colonic tuberculosis. The colonoscopic appearances of tuberculosis included: mucosal nodules and ulcers, stricture with nodules and ulcerations, and mucosal nodules with or without pseudopolypoid folds. In 12 (41%) of 29 patients colonoscopy biopsies enabled a histologic diagnosis to be made on the basis of typical granulomas. Culture of biopsy tissue on Lowenstein Jensen media isolated Mycobacterium tuberculosis in six (40%) of 15 patients. Combined histologic and bacteriologic evaluation established the diagnosis in 60% of patients. We conclude that even though target biopsy is an effective method of diagnosis, anti-tuberculous chemotherapy may be started on the basis of the endoscopic appearance if there is a high clinical suspicion of tuberculosis.

Acute chylous peritonitis with associated intestinal tuberculosis.

Acute chylous peritonitis is a rare condition that may be a sign of occult disease. However, in the majority of cases an underlying cause has not been demonstrated. The following is a case report of a five-year-old boy with acute chylous peritonitis with associated intestinal tuberculosis.
