Background: Etiology of chronic diarrhea can be established through non-invasive examination such as stool examination and stool culture. Colonoscopy is an invasive
Method, which is occasionally needed to discover the etiology of chronic diarrhea. Objective: To recognize the characteristics of chronic diarrhea based on stool examination and colonoscopy results.
Descriptive study on patients with chronic diarrhea who came to Cipto Mangunkusumo hospital since 1 June to 31 August 2005. Laboratory tests were conducted in accordance with clinical indication. Data was presented in distribution tables.
There were 41 patients with chronic diarrhea. Stool examination were performed only in 38 patients with negative-gram infection (86.8%). Stool cultures were performed in 27 patients with positive results of non-pathogenic Escherichia coli (85.2%). Stool parasite examination and concentration tests were performed in 17 patients, with 47.0% positive results as follow: Microsporidia 29.4%, Blastocystis hominis 11.8% and Giardia lamblia 5.9%. Colonoscopy examinations were performed in 6 patients and all patients indicated ulcerative colitis appearance with 50% histopathological impression of infective colitis.
Stool examination in chronic diarrhea primarily indicates positive infection. Bacterial stool culture mostly includes non-pathogenic Escherichia coli, while parasite stool examination largely includes Microsporidia. Biopsy examination tends to reveal infective colitis.
