The clinicopathologic features and the comparative analysis of diagnostic methods in 42 patients having intestinal tuberculosis were studied. In all the cases, clinical and colonoscopic diagnosis was confirmed by histological examination. Abdominal pain was the most common symptom (54%). Twenty nine patients had active pulmonary tuberculosis which was confirmed by a chest X-ray, or an AFB smear and a culture of sputum. A transverse ulcer with surrounding hypertrophic mucosa and multiple erosion was the usual colonoscopic findings. The granulomas were usually located in the just upper and lower portion of muscularis mucosa. The direct smear and culture of the fresh biopsy material showed AFB in 11 (32.4%) and 12 cases (36.4%) respectively. Ziehl-Neelsen staining in serially sectioned slides from formalin-fixed, paraffin- embedded tissue revealed AFB in 15 cases (35.7%). An immunohistochemical stain for Mycobacterium bovis was done in all cases and 13 cases were positive (31%). A polymerase chain reaction (PCR) was done and showed positivity in 4 out of 20 cases of fresh biospy material and 12 out of 40 cases in paraffin embedded tissue. For the conclusive diagnosis of intestinal tuberculosis, a Ziehl-Neelsen stain is the most sensitive, fast, and cost-effective method. The diagnostic accuracy will be increased when other diagnostic methods such as tissue culture and PCR are coupled with this simple staining method.
BACKGROUND The incidence of Crohn's disease in the upper digestive tract, and especially in the stomach, is recently increasing. Focal inflammatory reaction without Helicobacter pylori (H. pylori) infection is thought to be the characteristic pathologic findings suggesting Crohn's disease in the stomach. Yet gastric involvement of Crohn's disease has not been studied in Korea. We studied the endoscopic and pathologic findings of patients with Crohn's disease in the stomach by taking biopsies. METHODS Thirty patients with Crohn's disease who underwent gastroduodenoscopy followed by biopsies were included in the study. The pathology of the gastric biopsy specimens and the presence of H. pylori were evaluated. RESULTS Among 30 cases, 22 cases (73.3%) were H. pylori negative and 8 cases (26.7%) were H. pylori positive. For the H. pylori negative cases, all but one cases showed pit abscess and focal lymphocytic collections in the antrum.
Granulomas were found in 6 cases (20%) and they were exclusively located in the antrum. CONCLUSIONS In the stomach, pit abscess and focal lymphocytic collections that are not associated with H.
pylori infection are the characteristic pathologic findings found in Crohn's disease.
Anisakiasis refers to the accidental infection of humans by a marine nematode as a result of eating a raw flsh which contains larval stages of the nematode sub-family Anisakidae. This patient developed acute epigastric pain three days after eating a raw flsh, Astroconcer myriaster.
Gastrofiberscopy revealed Anisakis larva invading the stomach wall and the larva could be extracted using a biopsy forceps via gastrofiberscopy. The worm was identified as Terranova type A larva based on their morphologic features such as its length, width, intestinal cecum reaching to anterior one-third level of ventriculus and a mucron at posterior end.
