[Short bowel ileus due to a stenotic ileocecal tumor of tuberculous origin].

Abdominal tuberculosis is a rare disease. Therapy usually consists in drug treatment while surgery is only performed in complicated cases. We report on a 75 year-old man who presented with clinical and radiologic signs of bowel obstruction. The patient complained of weight loss and B-symptoms. There was a history of drug treatment for tuberculosis of the neck and throat in the medical department four weeks prior to admission. Intraoperatively a coecum stenosis was found due to a large tumor that macroscopically appeared with a diffuse carcinomatosis of the peritoneum. A right hemicolectomy was performed. Histopathology findings revealed a granulomatous inflammation with epithelioid cells. Signs of peritoneal carcinomatosis were not seen. The patient recovered well after an additional tuberculostatic treatment and was discharged after 14 days. At present he is free of symptoms. Even after tuberculostatic treatment lymphatic tuberculosis might show signs of progression that can lead to an abdominal presentation.

Abdominal tuberculosis in children.

UNLABELLED: Abdominal tuberculosis (AT) is a rare cause of intraabdominal infection. Surgical intervention is rarely indicated, other than obtaining a specimen for histopathological diagnosis or for the treatment of complications. METHODS: The medical records of 14 patients who were operated on after the diagnosis of AT between 1983 and 2000 were reviewed retrospectively. RESULTS: Median age was 7 years (6 months to 10 years). The presenting clinical signs and symptoms were as follows: colicky abdominal pain (9), weight loss (8), abdominal mass (6), vomiting (5), and night fever (5). Two patients were operated at another centre and referred to our department with faecal fistula and severe malnutrition. Twelve patients were operated on, while diagnostic laparoscopy was performed in two. In uncomplicated cases, surgical intervention was limited to sampling of peritoneal tissue, lymph node and ascites. The reasons for surgical intervention were intestinal obstruction (9), abdominal mass and ascites (6), psoas abscess (1) and intussusception (1). Adhesive peritonitis and ileal loops were the cause of abdominal mass. Necrosis of the bowel (2) and perforation (1) were detected in three patients. The diagnosis was confirmed either by histopathological or microbiological examination. In eight patients, AT was defined at the intestinal mesentery, in three patients it was localised to the peritoneum and in two patients the disease was diffuse. All patients except one with faecal fistula survived and were treated successfully with antituberculous therapy (isoniasid, rifampicin, streptomycin and pyrazinamide combination). CONCLUSION: The diagnosis of AT is difficult before presentation with complications of intraabdominal infection. Since the response to chemotherapy is usually excellent in patients with suspected AT, aggressive surgery should be avoided and initial surgical intervention should be limited to tissue and/or fluid sampling.

Endoscopic biopsies from normal-appearing terminal ileum and cecum in patients with suspected colonic tuberculosis.

BACKGROUND AND STUDY AIMS: Colonic tuberculosis is generally diagnosed by colonoscopy and targeted biopsy of lesions. However, the diagnostic yield of colonic biopsies is not very good. So far as we are aware, there have been no studies investigating the role of biopsies from endoscopically normal-appearing cecum and terminal ileum in diagnosing colonic or ileal tuberculosis, or both. PATIENTS AND METHODS: Patients with a clinical suspicion of colonic tuberculosis, in whom no endoscopic abnormalities were found on colonoscopy or ileoscopy, were included in the study. Multiple biopsies were obtained from the cecum and ileum. RESULTS: Fifty patients were studied. Intubation of the terminal ileum was possible in 43 patients (86 %). Histological examination of biopsies obtained from the cecum and terminal ileum showed noncaseating granuloma in two patients. Both of these biopsies were from the terminal ileum. In two other patients, collections of loosely arranged epithelioid cells were observed. This established the diagnosis in these four patients (8 %). In the remaining 46 patients, histology showed nonspecific inflammation in 18 patients (in the cecum in 15 and in the terminal ileum in seven). The other biopsies did not show any abnormalities (33 from the cecum, 34 from the terminal ileum). CONCLUSIONS: Histological examination of biopsies from the normal-appearing cecum and terminal ileum is useful in a small but significant number of patients with colonic tuberculosis.

Tuberculous colonic strictures: impact of dilation on diagnosis.

BACKGROUND AND STUDY AIM: Colonic strictures are commonly encountered in patients with colonic tuberculosis. If the colonoscope cannot be negotiated past the stricture the procedure is abandoned, the colonic mucosa proximal to the stricture cannot be inspected, and therefore lesions in these locations may be missed. PATIENTS AND METHODS: 130 patients with colonic tuberculosis were studied. Of these 22 (17 %) had impassable colonic strictures. These strictures were dilated, the colonic mucosa proximal to the strictures was then inspected, and biopsies were obtained from lesions of suspicious appearance. RESULTS: All strictures could be dilated. No abnormality was found in 11 patients. In the other 11 patients one or more additional findings were noted on colonoscopy after dilation. A second stricture was found in three patients. Nodularity and/or ulceration was observed in the colon proximal to the site of the primary stricture in ten patients. Dilation of the strictures and histological examination of the biopsy from target lesions of the proximal colon contributed to making the definitive diagnosis in five patients. The diagnosis was not altered in the remaining six patients. CONCLUSION: Dilation of colonic strictures facilitates inspection of the colonic mucosa proximal to the strictures, enabling biopsy of target lesions. This approach offers important diagnostic clues and confirmation of the diagnosis in several patients in whom lesions might be missed if strictures are not dilated.

Clinical, colonoscopic, and histological profile of colonic tuberculosis in a tertiary hospital.

BACKGROUND AND STUDY AIMS: Colonic tuberculosis is not uncommon in developing countries. As emigration to the West increases, it is worthwhile to recall the clinical, colonoscopic, and histopathological features of this condition. PATIENTS AND METHODS: The clinical, colonoscopic and histopathological findings were evaluated in 43 patients with colonic tuberculosis. RESULTS: Abdominal pain, weight loss, diarrhea, fever, and a lump in the abdomen were the commonest symptoms. Extraintestinal tuberculosis was present in 11 patients (26 %). Colonoscopy revealed ulcers in 30 patients (70 %), nodules in 24 (56 %), a deformed cecum and ileocecal valve in 17 (40 %), strictures in 10 (23 %), polypoid lesions in six (14 %), and fibrous bands forming mucosal bridges in three (7 %). The cecum and ascending colon were the commonest sites involved. Segmental tuberculosis was seen in six of the 32 patients (19 %) in whom full-length colonoscopy could be performed. Two or more sites were involved in 19 patients (44 %). Histopathology revealed well-formed granulomas in 23 patients (54 %). Fourteen of the above patients (61 %) had caseation and 11 (48 %) had confluence of the granulomas. Acid-fast bacilli were present in the biopsies from two patients (5 %). Ill-formed granulomas were seen in seven patients (16 %) and chronic inflammatory changes in 13 (30 %). Despite the various histopathological findings, all of the patients responded to antitubercular treatment and continued to remain asymptomatic during the follow-up period. CONCLUSIONS: Colonoscopy with biopsy is a useful method for diagnosing colonic tuberculosis. Even in the absence of the classic histopathological features, a therapeutic trial may be indicated in a given clinical and colonoscopic setting. Follow-up is essential.

Analysis of colonoscopic findings in the differential diagnosis between intestinal tuberculosis and Crohn's disease.

BACKGROUND AND STUDY AIMS: Intestinal tuberculosis and Crohn's disease are chronic inflammatory bowel disorders that are difficult to differentiate from one another. This study aimed to evaluate the diagnostic value of various colonoscopic findings in the differential diagnosis between intestinal tuberculosis and Crohn's disease. PATIENTS AND METHODS: Colonoscopic findings on initial work-up were prospectively recorded in patients with an initial diagnosis of either intestinal tuberculosis or Crohn's disease. These findings were analyzed after a final diagnosis of intestinal tuberculosis (n = 44) or Crohn's disease (n = 44) had been made after follow-up. RESULTS: Four parameters (anorectal lesions, longitudinal ulcers, aphthous ulcers, and cobblestone appearance) were significantly more common in patients with Crohn's disease than in patients with intestinal tuberculosis. Four other parameters (involvement of fewer than four segments, a patulous ileocecal valve, transverse ulcers, and scars or pseudopolyps) were observed more frequently in patients with intestinal tuberculosis than in patients with Crohn's disease. We hypothesized that a diagnosis of Crohn's disease could be made when the number of parameters characteristic of Crohn's disease was higher than the number of parameters characteristic of intestinal tuberculosis, and vice versa. Making these assumptions, we calculated that the diagnosis of either intestinal tuberculosis or Crohn's disease would have been made made correctly in 77 of our 88 patients (87.5 %), incorrectly in seven patients (8.0 %), and would not have been made in four patients (4.5 %). CONCLUSIONS: A systematic analysis of colonoscopic findings is very useful in the differential diagnosis between intestinal tuberculosis and Crohn's disease.

Segmental tuberculosis of the colon diagnosed by colonoscopy.

We describe the case of a woman with rectorrhagia and rectal tenesmus. Colonoscopy revealed a 3-4 cm-long ulcerated lesion with a reduced colon lumen 35 cm from the anus, and multiple biopsies were obtained from the ulcerated region, but histopathology was non-specific. Biopsy culture was positive for M. tuberculosis. Anti-tuberculous chemotherapy was initiated on the diagnosis of segmental tuberculosis of the colon. Subsequent evolution was favorable, both clinically and endoscopically. Emphasis is placed on the importance of colonoscopy and biopsy in the diagnosis of tuberculosis of the colon.

Colonoscopic diagnosis and medical treatment of ten patients with colonic tuberculosis.

Ten patients with tuberculous enterocolitis were diagnosed colonoscopically. In four, the diagnosis was confirmed by positive acid fast stain or the presence of caseating granuloma in colonic biopsy material or ileal washings. In one other patient a cervical lymph gland revealed acid-fast bacilli. He was the only patient with extraintestinal disease, indicating that primary tuberculous colitis is probably more common than secondary in Saudi Arabia. In the other five patients the colonoscopic diagnosis was confirmed by a complete response to antituberculous triple therapy. Six patients had hypertrophic, two ulcerohypertrophic and two widespread ulcerative lesions. Colonoscopy with biopsies has definite advantages over barium enema in diagnosis. After thus excluding malignancy, Crohn's disease remains the most important differential diagnosis. A ten-week therapeutic trial of antituberculous treatment is recommended in patients from high-risk populations with a typical history and colonoscopic picture to avoid the morbidity and mortality of diagnostic laparotomy.

Tuberculous gastric ulcer.

This is a case report on tuberculosis of the stomach in a 70-year-old woman who, submitted to an endoscopic examination for uncharacteristic upper abdominal complaints, revealed multiple ulcers in the aboral part of the stomach, together with a thickening of the gastric wall. Histologically, caseating epithelioid cell granulomas were found, and only a single acid-fast tubercle (TB rod). As a further specific manifestation, tuberculous spondylitis developed, which was treated surgically. Under anti-tuberculous treatment, the gastric ulcers healed. The clinical-endoscopic picture, the pathogenesis, complications and differential diagnosis are discussed on the basis of current literature.
